Sucrose is common sugar. It is a disaccharide, and a molecule made up of two monosaccharides: glucose and fructose. Sucrose normally happens in plants, from which table sugar is refined. It has the molecular formula C12H22O11.


Sucrose intolerance

Sucrose narrow-mindedness or hereditary sucrase-isomaltase inadequacy (GSID) is the condition where sucrase-isomaltase, a catalyst essential for the legitimate digestion of sucrose (sugar) and starch (for instance, grains), isn’t delivered or the chemical created is halfway utilitarian. And non-utilitarian in the small digestive tract.

Symptoms of sucrose intolerance

Many people with sucrose intolerance, clinically known as a congenital sucrase-isomaltase deficiency (CSID), lack sucrase, the enzyme necessary for the digestion of sucrose. An individual with sucrose bigotry can’t process table sugar and, subsequently, creates gastrointestinal manifestations in the wake of eating nourishments that contain sucrose.

Many of those affected with CSID also have varying amounts of isomaltase and maltase-glucoamylase, the enzymes necessary for the digestion of starch. These people can also experience gastrointestinal symptoms from starch consumption.

Patients with sucrose prejudice can encounter gentle to serious gastrointestinal uneasiness when they devour nourishments containing sucrose as they travel undigested through the small digestive system and enter the internal body. Resident bacteria in the large intestine (colon) feed on the undigested sugar through a process called “fermentation.”

This fermentation leads to increased gas production. When undigested substances are not absorbed in the large intestine, an osmotic draw of water into the large intestine causes watery diarrhea. The gastrointestinal symptoms can vary in infants, children, and adults affected by this enzyme deficiency.

Infants and children

The indications of sucrose bigotry don’t show up in newborn children until they ingest sucrose and dull nourishments, for example, natural product juices, strong nourishments, normal infant nourishments, milk equations, and meds improved with sucrose. Breastfed infants may not show symptoms until a milk-based formula is added to their diet or they start eating solid foods.

  • Constant stomach torment, watery runs, and inability to flourish (poor actual development) are common indications of sucrose bigotry.

  • Stomach expansion (gas), gassiness, persistent colic, touchiness, abraded (scraped spots and bothering) rear end, retching, and diaper rash can be indications of pediatric sucrose bigotry.

  • Hospitalization may be required if symptoms result in dehydration, malnutrition, muscle wasting, and infant weakness.

  • Sucrose intolerance is often diagnosed in infants as chronic, non-specific diarrhea known as “infant diarrhea.”

  • Older children are often mistakenly diagnosed with irritable bowel syndrome (IBS) because cramping, abdominal pain, gas, and intermittent diarrhea are symptoms common in IBS and sucrose intolerance.

Unfortunately, older children can learn to live with their symptoms and are never properly diagnosed. Other incorrect diagnoses include milk protein intolerance, food allergies, and chronic, non-specific diarrhea. It’s important to note that sucrose intolerance is a genetic disease that infants and children cannot outgrow.

For Adults

Adults, too, can learn to live with their gastrointestinal symptoms and accept that their problems are normal. Adults have symptoms comparable to babies and youngsters. However, because the gastrointestinal tract is longer in adults, their symptoms may not be as severe or as common.

Symptoms in adults may be limited to an increased incidence of loose stools, abdominal disorders, and gas.

  • Episodic watery diarrhea can occur when ingesting foods high in sucrose.

  • Diarrhoea can also alternate with constipation, leading to a misdiagnosis of IBS. In infants, children, and adults, failure to ingest sucrose and starch from food can impair the absorption of other nutrients and disrupt the normal hormonal regulation of gastrointestinal functions.

  • Improperly absorbed carbohydrates slow the rate at which consumed food motions from the tummy to the small intestine while also increasing the rate at which consumed food reaches the large intestine in the small intestine.

  • These progressions in gastrointestinal travel time add to the malabsorption of starch, fat, and monosaccharides.

  • The intensity of symptoms can be altered by sucrose and starch consumption, bacterial activity in the large intestine, absorption capacity, and stomach and low intestine transit speeds.

Repeating manifestations, for example, persistent runs, unexplained stomach torment, gas, weight reduction, successive solid discharges, gassiness, gas, and spewing, ought not to be disregarded. Constant gastrointestinal side effects ought to be examined by a gastroenterologist.

Facts On Sucrose Intolerance

Sucrose is generally known as table sugar, the white stuff. This sugar is found in many regular nourishments like apples and handled food sources like frozen yogurt. Sucrose is a disaccharide sugar particle, a mix of two monosaccharides sugar atoms, glucose and fructose. It is thought that 1 in 5,000 persons of European descent has a genetic sucrase-isomaltase deficiency, which means they can’t eat sugar (GSID).

Glucose Sucrose
Glucose is the most significant monosaccharide since it is the body’s primary energy source. Sucrose is derived from sugar cane or sugar beets and is frequently referred to as table sugar.
Glucose is also known as blood sugar because it circulates in the blood, and the enzymes glucokinase or hexokinase initiates its metabolism. Fruits and vegetables contain sugar naturally.
Most carbohydrates you consume are converted into glucose, either utilized immediately for energy or stored in muscle cells or the liver as glycogen for later use. The enzyme beta-glucosidase splits sucrose into its component sugar units, glucose, and fructose, upon consumption.
Insulin is largely released due to rising blood glucose levels, and insulin promotes glucose uptake into cells. The body normally responds to the glucose content of the meal, but fructose absorption also happens simultaneously.

Sucrose narrow-mindedness is now and again mistaken for other sugar bigotries, for example, fructose or lactose, and gastrointestinal issues, including crabby entrail condition. You should be aware of some facts concerning sucrose and sucrose intolerance.

  1. Common sucrose intolerance (GSID) symptoms are excess gas, diarrhea, stomach cramps, nausea, or vomiting.

  2. Symptoms of sucrose intolerance (GSID) in infants and children include chronic abdominal pain, watery diarrhea, failure to thrive (poor physical growth), abdominal swelling, gassiness, colic, irritability, vomiting, and diaper rash.

  3. An itemized rundown of nourishments high in sucrose. Some offenders are apple juice, flavored coffee creamer, and prepackaged pasta sauce.

  4. As per the American Heart Association (AHA), the greatest measure of added sugars you ought to eat in a day is 150 calories each day for men (37.5 grams or nine teaspoons) and 100 calories every day for ladies (Aug. Grams or 6) teaspoons).

  5. Each person with sucrose intolerance (GSID) is different, so no one diet helps everyone. Patients with GSID need to work with their doctor and a registered dietitian (RD) to develop a personalized diet that meets their needs. As a rule, the dietary treatment for GSID centers around sugar (sucrose) and starch (isomalt and maltose) limitations. The degree of restriction depends on the patient.

  6. After completing an initial two-week sucrose elimination diet, foods containing sucrose are gradually added to the diet to determine how much sucrose can be tolerated. It is suggested that just a single new food be once again introduced into the eating regimen each three to five days before adding the following new food.

  7. This list of fruits and vegetables is generally well-tolerated and not tolerated by people with sucrose intolerance (GSID).

  8. The effectiveness of the diet depends on working with a licensed dietitian who is knowledgeable in glucose-sucrose interaction disorder (GSID). The registered dietitian will instruct you on how to keep a food diary and gradually include new foods into your diet.

Sucrose formula

Sucrose is a non-reducing disaccharide of glucose and fructose linked through their anomeric carbons. It is industrially from sugar sticks, sugar beet (Beta Vulgaris), and different plants. It is utilized widely as food and sugar. Sucrose is obtained by crushing and extracting sugar cane (Saccharum officinarum) with water or by extracting the sugar beet (Beta vulgaris) with water, evaporating and cleaning it with lime, carbon, and various liquids.

Sucrose is also available from sorghum. Sucrose is found in small amounts in honey and maple syrup. Sucrose is used as a sweetener in food and soft drinks, in the production of syrups, inverted sugar, confectionery, canned goods and jams, demulsifiers, pharmaceutical products, and caramel. Sucrose is a synthetic moderate for cleansers, emulsifiers, and other sucrose subsidiaries.

Sucrose is broad in seeds, leaves, natural products, blossoms, and underlying foundations of plants, where it goes about as an energy store for digestion and a carbon hotspot for biosynthesis. The yearly creation of sucrose is over 90 million tons, chiefly from the juice of sugar stick (20%) and sugar beet (17%). Notwithstanding its utilization as sugar, sucrose is utilized in nourishments as an additive, cell reinforcement, dampness control specialist, stabilizer, and thickener.

The molecular formula of sucrose is: C12H22O11

Sucrose molar mass

Element Weight
Mass of carbon 12 g.
Mass of hydrogen 1 g.
Mass of oxygen 16 g.

The chemical formula of sucrose is C₁₂H₂₂o₁₁.

  • Molar mass = 12 × 12 + 1 × 22 + 16 × 11

  • = 144 + 22 + 176

  • = 320 + 22

  • = 342 g / mole.

Therefore the molar mass of sucrose corresponds to 342 g / mol.

Sucrose structure

Sucrose is shaped when a monomer from glucose and a monomer from fructose is connected to frame a glycosidic bond in a drying-out response. Typically, a monosaccharide’s carbon atoms are counted backward from the carbonyl group’s terminal carbon.

Iron sucrose

Sugared iron is often referred to as “mineral iron.” Among its numerous uses, iron helps carry oxygen throughout the body via the blood.

  • Iron sucrose is utilized to treat iron inadequacy weakness in individuals with kidney illness.

  • Iron sucrose is unsuitable for treating other conditions of anemia not compelled by iron depletion.

  • The following are not all possible uses for injectable iron sucrose.

  • Follow all bearings on your medication mark and bundling. Your medical conditions, allergies, and prescription drugs should be disclosed to your healthcare providers.

Iron sucrose side effects

Get quick medical help if you experience any of the following allergic reaction symptoms: itching, hives, wheezing, problem in breathing, or swelling of the tongue, face, lips, or neck.

Tell your doctors right away if you have the following:

  • Chest pain;

  • A feeling of dizziness, like you might pass out; or

  • Increased blood pressure (severe headache, pounding in the neck or ears, anxiety, confusion).

Common side effects can include:

  • Headache, dizziness;

  • Pain in an arm or leg;

  • Nausea, vomiting;

  • Diarrhea;

  • Muscle or joint pain, back pain;


Iron sucrose is used to treat iron inadequacy weakness in individuals with kidney illness. It is not suitable for treating other forms of anemia that are not caused by iron deficiency. Side effects of iron sucrose include hives, itching, trouble breathing, and expanding the face, lips, tongue, or throat.

Frequently Asked Questions - FAQs

People asked many questions about “sucrose.” We discussed a few of them below:

1. Is sucrose a monosaccharide?

No, sucrose is not a monosaccharide but a disaccharide, a molecule made up of two monosaccharides: glucose and fructose. Sucrose is naturally made in plants that are used to refine table sugar. It has the molecular formula C12H22O11.

2. Is sucrose a reducing sugar?

Sucrose is a non-lessening sugar because the two monosaccharide units are held together by a glycosidic connection between C1 of α-glucose and C2 of β-fructose. Since the lessening gatherings of glucose and fructose are engaged with developing glycosidic bonds, sucrose is a non-decreasing sugar.

3. What is sucrose made of?

Sucrose is made from glucose and fructose.

4. Is sucrose a carbohydrate?

Carbohydrates (also called saccharides) are molecular compounds of only three elements: carbon, hydrogen, and oxygen. Smaller molecules are monosaccharides (such as glucose) and disaccharides (such as sucrose). They’re commonly referred to as “sugar” in everyday speech.

5. How are sugar and sucrose different?

Sucrose is another name for sugar, often known as table sugar. In addition to sucrose, there are numerous more forms of sugar, including glucose, galactose, fructose, and lactose.

6. What is the name of fruit sugar?

Due to its natural occurrence in most fruits, fructose is usually referred to as “fruit sugar.” It also occurs naturally in honey, sugar beets, sugar cane, and vegetables, among other plant-based meals. Fructose is the sweetest naturally occurring sugar and is 1.2 to 1.8 times sweeter than sucrose (table sugar).

7. What is the name of milk sugar?

Lactose is a carbohydrate composed of one molecule of glucose and one molecule of galactose. Lactose, which comprises between 2 and 8 percent of the milk of all animals, is commonly referred to as milk sugar.

8. Is sucrose bad for you?

Many fruits and vegetables naturally contain sucrose, which is also processed to create granulated home sugar. Eating enough plant-based foods for natural sucrose to be a health problem is virtually impossible. Still, it’s fairly easy to consume too much-refined sucrose through baked goods, sweets, and desserts.

9. Is sucrose an enzyme?

Sucrose is digested in the small intestine by the -glucosidase sucrase into fructose and glucose. The Upper GI brush edge converts 10-25% of fructose to glucose. Monosaccharides are absorbed and produced in the liver through the portal vein.

10. How can I measure molar mass?

Multiply the element’s atomic mass by the compound’s atom count. It tells you how much each ingredient contributes. For HCl, hydrogen’s molar mass is 1.007 g/mol, and chlorine’s is 35.453 g/mol.


The scientific word for table sugar is sucrose. Sucrose is a disaccharide composed of the monosaccharides glucose and fructose. People often call it “table sugar,” but it can also be discovered in fruits, vegetables, and nuts. However, refined sugar may also be manufactured economically from sugar cane and sugar beets.

Sucrose intolerance is a rare disease, but it can cause quite a few digestive disorders if the diet is not adjusted correctly. Know what foods you should avoid.

What is sucrose intolerance?

The sucrose is table sugar, white sugar, or table sugar. Due to the short length of its molecule, this rapidly absorbed sugar results from the combination of two monosaccharides, the smallest components within the group of carbohydrates, and a glucose molecule and a fructose molecule. By containing two molecules of saccharides or sugars, sucrose is a disaccharide.

In many cases, sucrose intolerance is associated with a deficit of other digestive enzymes that digest other sugars, such as lactose, milk sugar or fructose, and fruit sugar. In these cases, the alteration affects sugars that cannot be digested normally due to enzyme deficiency.

Causes and symptoms of sucrose intolerance

The cause of sucrose intolerance is the deficiency of the enzyme that assists in the digestion of sugar: sucrase, sucrase, or invertase. This deficiency has a genetic origin and is present from birth. On some occasions, and when there is already a certain predisposition, this lack of sucrase can be unnoticed until ages when sucrose consumption is higher. In the case of babies, it is usually at the time when fruits or infant formulas with sugar addiction are introduced that symptoms are caused, and the intolerance is discovered.

Alleles for sugar intolerance genes must be passed down from both parents for a kid to be affected (so-called primary sucrose intolerance). Irritable bowel syndrome, becoming older, and diseases of the small intestine can also lead to glucose intolerance (secondary sucrose intolerance).

Sulfite intolerance can be diagnosed with the help of clinical testing. Biopsy of the small intestine is the gold standard for determining enzyme activity. GSID can be diagnosed using this test. The sucrose breath test and a genetic test for the lack of particular genes thought to be involved in GSID can also aid in the diagnosis, although neither is definitive.

Dietary supplements or drugs can be used to replace the missing enzyme or to introduce healthy bacteria into the immune system.

Also, some children can tolerate higher amounts of sucrose over the years. What begins as a serious digestion problem can lead to minor alterations.

Signs and Symptoms

  1. Abdominal cramps and bloating

  2. Diarrhea and constipation

  3. Vomit

  4. Hypoglycemia and headaches

  5. Poor weight gain and growth

  6. Upper respiratory tract and viral diseases

  7. Anxiety and palpitations

  8. Excessive gas production

Symptoms and complications of sucrose intolerance

The symptoms of intolerance to sucrose are mainly gastric or intestinal-type with abdominal pain, gastric distension, discomfort, or diarrhea. Suppose the problem is not treated and the symptoms continue more or less chronically. In that case, the loss of micronutrients due to diarrhea can affect the nutritional status.

Similarly, dehydration could also be triggered if fluid losses are not compensated for. All this process could lead to a delay in the growth and development of children, as well as generalized fatigue with the presence of anemia or various nutritional deficits in adults.

The first basic step in treatment should be early diagnosis. Thus, the sooner you know if you have an intolerance, the sooner you can start treatment and minimize the consequences of this problem.

Diet change

The degree to which a person with CSID can digest sucrose or starch sugars varies on a numeral of variables, including the following:

  • The degree of individual function of the digestive enzyme sucrase-isomaltase
  • The efficiency of the gastrointestinal tract’s other activities
  • The amount of sucrose and starch carbohydrates taken
  • The presence of various health conditions that might impact digestion

For these reasons, a restricted diet must be specific for each patient with CSID. Before a patient changes to diet, a patient needs to speak with a health care provider, especially if the patient is underweight or does not gain weight as expected. It is also recommended that the patient works with a registered dietitian or nutritionist who can help identify the foods that can and cannot be tolerated.

The treatment of sucrose intolerance is based on diet control, avoiding foods containing sucrose to prevent its accumulation undigested in the intestine. This control should be more exhaustive the lower the sucrose tolerance threshold that the person has. It is important to work since sucrose is not only found in table sugar as such. Sucrose in food is highly diversified since it is used in many products, so it requires constant vigilance.

Sucrose foods to avoid

Food groups are some of the ones with the highest sucrose content.

  • Some fruits contain not inconsiderable amounts of sucrose, such as mango, pineapple, peach, apricot, nectarine, and fig. Also, some dried fruits like dates.

  • Among vegetables, carrots, beets, cabbage, and tomatoes are some of the richest in this disaccharide.

  • Legumes: peas contain quite a bit of sucrose.

  • Sugary drinks: commercial carbonated and sugary soft drinks, fruit juices with added sugar.

  • Sugary dairy: condensed milk, sweetened yogurt, and other sweet dairy desserts.

  • Pastries, pastries, cakes, cookies.

  • Chocolate with added sugar, jam, ice cream, and caramel.

  • Candy, sweets, various sweets.

  • Sweet corn, sugary cereals.

After the diagnosis of sucrose intolerance, the affected person should test their tolerance to this disaccharide in the following weeks. Initially, take minimal amounts of sucrose in food and gradually and gently increase the intake if symptoms do not appear. If digestive symptoms appear, reduce sucrose in the diet again until the situation normalizes.

Likewise, it is convenient to test the tolerance again from time to time since it can be modified over time.


Since the primary form of sucrose intolerance is caused by an inherited gene mutation, this metabolic disorder cannot be prevented. Anyone suffering from chronic inflammatory bowel disease and, therefore, secondary to sucrose intolerance will always need comprehensive nutritional advice and consistent medical attention.
