　　maltose, organic compound composed of two glucose molecules linked together. The compound (C12H22O11) is a disaccharide formed during the breakdown of starch. It occurs naturally in sprouted grains, such as barley, corn (maize), and wheat, and is found in malted foods and beverages, particularly beer, in which it is fermented by yeast to produce alcohol. The glucose units of maltose are linked by a glycosidic bond, the nature of which leaves one of the glucose molecules in maltose with a free aldehyde that readily gives up electrons to other molecules. As a result, maltose is easily broken down, rendering it ...(100 of 363 words)
