What is sucrose made of?

Sucrose is a disaccharide composed of one glucose molecule and one fructose molecule joined together by a glycosidic bond. This specific arrangement and combination of monosaccharides give sucrose its unique characteristics and metabolic functions.

Both glucose and fructose are simple sugars, or monosaccharides, that serve as essential energy sources and participate in various metabolic pathways in living organisms. When sucrose is consumed, it is broken down into these two monosaccharides by the enzyme sucrase, allowing glucose and fructose to be absorbed into the bloodstream.

The other options do not accurately represent the composition of sucrose: two glucose molecules refer to maltose, one glucose and one galactose represent lactose, and glucose only would refer to the monosaccharide form without any other component. Understanding the structure of sucrose is fundamental in biochemistry, especially in relation to carbohydrate metabolism and energy production in living organisms.
