Difference in Sucrose and Fructose

Overview
Sucrose and fructose are two common sugars that can occur naturally in foods or that you can add to foods to increase their sweetness. Rift Gold While the two sugars have different chemical structures, they're very similar in many ways, including the ways that your cells use them for energy.

Fructose
The fructose molecule is a monosaccharide, meaning it's made up of a single sugar ring. Like many other monosaccharides, including the much more common sugar glucose, fructose has the chemical formula C6H12O6. RIFT Platinum It's commonly called "fruit sugar" because fruit is one of the common natural sources of fructose. Like all carbohydrates, both sugars and starch, fructose contains 4 calories per gram consumed. However, it's much sweeter than other sugars, meaning it takes less fructose to sweeten a food than it would take glucose or table sugar.

Sucrose
Sucrose is table sugar. While it's not the most common sugar in nature -- glucose is more ubiquitous -- it's probably the most familiar of the sugars to humans. rift gold It's a disaccharide, meaning it consists of two separate monosaccharide units, chemically bonded together. Specifically, sucrose contains fructose bonded to glucose. Because of this, sucrose has a sweetness between that of glucose and the much sweeter fructose. It's chemical formula is C12H22O11.

Differences in Digestion and Absorption
Sweetness and structure aside, the major difference between sucrose and fructose has to do with how your body takes the sugars up into the bloodstream and cells. RIFT Platinum When you consume fructose, you absorb it immediately; you don't need to digest it. Sucrose, on the other hand, requires digestion. You use the enzyme sucrase to break sucrose into glucose and fructose, which you then absorb separately.

Cellular Use
Your cells take up glucose and fructose from the bloodstream. Fructose, TERA Gold regardless of the source, doesn't require any special chemical signal for cellular uptake. Glucose requires insulin, a pancreatic hormone, for cellular uptake. Once in the cells, however, fructose and glucose share common fates. You can burn them for immediate energy or store them for later energy use, either as glycogen or as fat. Glycogen is a carbohydrate stored in the liver and muscles, while fat is stored in adipose tissue.
