Sucrose (common name: table sugar, also called saccharose) is a disaccharide (glucose + fructose) with the molecular formula C12H22O11. Its systematic name is α-D-glucopyranosyl-(1→2)-β-D-fructofuranose. It is best known for its role in human nutrition and is formed by plants but not by higher organisms.
Physical and chemical properties
changePure sucrose is most often prepared as a fine, white, odorless crystalline powder with a pleasing, sweet taste.
