Detailed explanation-1: -Glycosidic bonds are cleaved by enzymes known as glycosidases. The three major disaccharides are sucrose, lactose, and maltose. Sucrose, which is formed following photosynthesis in green plants, consists of one molecule of glucose and one of fructose bonded via an -, -linkage.
Detailed explanation-2: -Maltose is composed of two molecules of glucose joined by an -1, 4-glycosidic linkage. It is a reducing sugar that is found in sprouting grain. Lactose is composed of a molecule of galactose joined to a molecule of glucose by a -1, 4-glycosidic linkage. It is a reducing sugar that is found in milk.
Detailed explanation-3: -Maltose is typically derived from starch and we can break down maltose disaccharides at the brush border of the small intestine by using an enzyme called maltase. Lactose is a disaccharide found in milk and it consists of a beta-D-galactose that is attached to an alpha-D-glucose.
