Glucose can adopt several different 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 "right-handed form" of glucose, denoted D-glucose. D-glucose is often referred to as dextrose, especially in the food industry. The term dextrose is derived from dextrorotatory glucose. Solutions of dextrose rotate polarized light to the right (in Latin: dexter = "right").
