What Is the Difference Between Sucrose, Glucose & Fructose? | Healthy Eating | SF Gate
Not all sugars are created equal, which matters when it comes to your health. Here's the difference between sucrose, glucose and fructose. Three common sugars—glucose, galactose, and fructose, share the same in milk, as part of a disaccharide made by glycosidic linkage to a glucose molecule. Your tongue can't quite distinguish between glucose, fructose and sucrose, but your body can tell the difference. They all provide the same.Aldose and Ketose - Glucose, Fructose, & Galactose Structures
However, it is very different from other sugars because it has a different metabolic pathway and is not the preferred energy source for muscles or the brain. Fructose is only metabolized in the liver and relies on fructokinase to initiate metabolism.
It is also more lipogenic, or fat-producing, than glucose. Unlike glucose, too, it does not cause insulin to be released or stimulate production of leptin, a key hormone for regulating energy intake and expenditure. These factors raise concerns about chronically high intakes of dietary fructose, because it appears to behave more like fat in the body than like other carbohydrates.
What is the relationship between D-glucose and D-fructose?
Sucrose Sucrose is commonly known as table sugar, and is obtained from sugar cane or sugar beets. Fruits and vegetables also naturally contain sucrose. When sucrose is consumed, the enzyme beta-fructosidase separates sucrose into its individual sugar units of glucose and fructose. The lactose disaccharide from milk is a major energy source for almost all animals, including human. Although not very water-soluble, and less sweet than glucose, it forms part of glycolipids and glycoproteins, which is found in many tissues.

The body can change glucose to galactose in order to enable the mammary glands to produce lactose. Galactose is natural and is a basic component of many things, being found in milk, tomatoes and many fruits and vegetables.
There is only one product range in the world that uses galactose as a basic food and drink ingredient, and that is a brand new range of energy drinks. Galactose has uniquely different properties compared to other sugars. These properties make it easier to lose and maintain weight; they are useful in warding off adult-onset diabetes; they give much steadier energy through time, and they provide the basis for products for athletes which allow them to perform better and longer. Galactose is a remarkable undiscovered sugar for the new Millennium.
Fructose Fructose's chemical name is levulose. Fructose is also called the fruit sugar. In foods, glucose is most commonly bound to another simple sugar to form either polysaccharide starches or disaccharides, such as sucrose and lactose 1.
Glucose is less sweet than fructose and sucrose 2. Fructose is sourced from sugar cane, sugar beets and corn. High-fructose corn syrup is made from cornstarch and contains more fructose than glucose, compared to regular corn syrup 3. Of the three sugars, fructose has the sweetest taste but least impact on your blood sugar 2. Summary Sucrose is made up of the simple sugars glucose and fructose. Sucrose, glucose and fructose are found naturally in many foods but also added to processed products.
On the other hand, disaccharides like sucrose must be broken down into simple sugars before they can be absorbed. Glucose Absorption and Use Glucose is absorbed directly across the lining of the small intestine into your bloodstream, which delivers it to your cells 45. It raises blood sugar more quickly than other sugars, which stimulates the release of insulin 6.
Monosaccharides Glucose Fructose Galactose
Insulin is needed for glucose to enter your cells 7. Once inside your cells, glucose is either used immediately to create energy or turned into glycogen to be stored in your muscles or liver for future use 89.

Your body tightly controls your blood sugar levels. When they get too low, glycogen is broken down into glucose and released into your blood to be used for energy 9. If glucose is unavailable, your liver can make this type of sugar from other fuel sources 9. Fructose Absorption and Use Like glucose, fructose is absorbed directly into your bloodstream from the small intestine 45.
It raises blood sugar levels more gradually than glucose and does not appear to immediately impact insulin levels 6 Your liver has to convert fructose into glucose before your body can use it for energy.
If you eat more fructose than your liver can handle, the excess is turned into cholesterol and triglycerides This may have negative health effects such as obesity, fatty liver disease and high cholesterol.
Sucrose Absorption and Use Since sucrose is a disaccharide, it must be broken down before your body can use it.
