'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

Pure sucrose is most often prepared as a fine, white, odorless crystalline powder with a pleasing, sweet taste. Large crystals are sometimes precipitated from water solutions of sucrose onto a string (or other nucleation surface) to form rock candy, a confection.
Like other carbohydrates, sucrose has a hydrogen to oxygen ratio of 2:1. It consists of two
