The Chemical Nature of Sucrose
Sucrose is a chemical compound with the molecular formula C12H22O11, classified as a disaccharide. This means it's made of two smaller monosaccharide units: glucose and fructose, linked together. This bond gives sucrose specific chemical properties, including not being a "reducing sugar". The body breaks this bond using the enzyme sucrase, allowing for the absorption of glucose and fructose.
Comparison Table: Sucrose vs. Other Common Sugars
Understanding sucrose is enhanced by comparing it to other common sugars.
| Feature | Sucrose | Glucose | Fructose | Lactose | Maltose |
|---|---|---|---|---|---|
| Classification | Disaccharide | Monosaccharide | Monosaccharide | Disaccharide | Disaccharide |
| Composition | Glucose + Fructose | Single Unit | Single Unit | Glucose + Galactose | Glucose + Glucose |
| Common Source | Sugarcane, Sugar Beets | Grains, Cornstarch | Fruits, Honey | Dairy Products | Sprouted Grains |
| Common Name | Table Sugar | Dextrose, Blood Sugar | Fruit Sugar | Milk Sugar | Malt Sugar |
| Body Absorption | Broken down, then absorbed | Absorbed directly | Absorbed directly (mostly in liver) | Broken down, then absorbed | Broken down, then absorbed |
| Sweetness (vs Sucrose) | Reference (1.0) | Less Sweet | Sweeter | Much Less Sweet | Less Sweet |
The Journey from Plant to Pantry
Table sugar comes primarily from sugarcane and sugar beets, which naturally contain high levels of sucrose. The production involves extracting, purifying, and crystallizing the sugar.

Health Considerations of Sucrose Consumption
Excessive intake of sucrose, particularly from added sugars, is linked to negative health effects. The WHO advises limiting free sugars to less than 10% of total energy intake. High added sugar diets are associated with weight gain, obesity, metabolic syndrome, and an increased risk of type 2 diabetes. It can also negatively impact cardiovascular health by raising blood pressure, causing inflammation, and increasing triglycerides. Additionally, sucrose contributes to dental caries by providing food for acid-producing mouth bacteria.
Conclusion
What is sucrose more commonly called is table sugar, a widely used disaccharide composed of glucose and fructose. While offering benefits in food preparation and as an energy source, excessive consumption of added sucrose is linked to significant health risks, including metabolic disorders, cardiovascular issues, and dental problems. Mindful consumption and a balanced diet are essential. For further details on health impacts, refer to resources like the Harvard Health article on sugar.
Understanding Sucrose: A Deeper Look
Is sucrose the same as high-fructose corn syrup (HFCS)?
No, sucrose is a disaccharide (glucose-fructose bond), while HFCS is a mix of free glucose and fructose, though both have similar sugar proportions. Research on metabolic differences is ongoing.
What is the chemical formula for sucrose?
The chemical formula is C12H22O11.
Are there healthier alternatives to sucrose?
Alternatives include natural sugars from whole fruits or non-nutritive sweeteners like stevia. Moderation is key for all added sugars.
Why is sucrose a key energy source?
Sucrose provides quick energy because it's easily broken down into glucose, the body's main fuel.
Does sucrose intake lead to dental problems?
Yes, mouth bacteria convert sugars like sucrose into acid that damages tooth enamel.
What happens to sucrose when it is heated?
When heated above 186°C, sucrose caramelizes, resulting in a brown color and distinct flavor.
Conclusion: The Ubiquitous Sugar
Sucrose is commonly called table sugar. This disaccharide, from sugarcane and sugar beets, is vital in our food system for sweetness and function. However, its overconsumption is a public health concern linked to metabolic and cardiovascular issues.
