Sucrose is a compound made up of one molecule of glucose joined to one molecule of fructose through a glycosidic bond. Unlike most complex sugars, also known as polysaccharides, the glycosidic bond in sucrose is formed at the non-reducing ends of both the glucose and fructose molecules.
This means sucrose, also known as table sugar, is considered a non-reducing sugar, as it does not a contain a free carbon atom. This prevents sucrose from further bonding to any other saccharide compounds.
Sucrose is generally a colorless white powder, and it has a chemical formula of C12H22O11. Sucrose is naturally formed by plants through the condensation of fructose and glucose.
