Glucose (C6H12O6, also known as D-glucose, dextrose, or grape sugar) is a simple aldosic monosaccharide found in plants. It is a monosaccharide that is absorbed directly into the bloodstream during digestion. It is an important carbohydrate in biology, which is indicated by the fact that cells use it as a secondary source of energy and a metabolic intermediate. Glucose is one of the main products of photosynthesis and fuels for cellular respiration.
Glucose exists in several different molecular structures, but all of these structures can be divided into two families of mirror-images (stereoisomers). Only one set of these isomers exists in nature- those derived from the particular chiral form of glucose that is denoted D-glucose, or D-glucose.
The chemical D-glucose is sometimes referred to as dextrose, a historical name that derives from dextrorotatory glucose because a solution of D-glucose in water rotates the plane of polarized light to the right (dextro). However, the D- in D-glucose refers to a chiral chemical similarity property in sugars, not the property of rotating light (for example, D-fructose rotates light to the left). For this reason, the D- and L- designations in sugars do not perfectly predict optical rotation, and do not refer to this property.
