Lactose and Fructose

Detailed explanation-1: -Maltose and isomaltose are the disaccharides (glucose-glucose) produced as end products of starch digestion. The diet also may contain lactose (galactose-glucose) and sucrose (fructose-glucose).
Detailed explanation-2: -Maltose, another common disaccharide, is condensed from two glucose molecules.
Detailed explanation-3: -Maltose is made of two molecules of glucose while sucrose is made up of one molecule of glucose and one molecule of fructose. Thus, option (C) Glucose and fructose is an incorrect answer. As monosaccharide of maltose is glucose, not fructose so option (D) Fructose only is incorrect.
Detailed explanation-4: -Mechanism of Maltase The mechanism of all Family GH13 enzymes is the hydrolysis of alpha-glucosidase linkage. Maltase is a disaccharide having a-(1->4) link connecting two glucose units that are used to dissolve maltose.
