Detailed explanation-1: -The bond formed between glucose and galactose monosaccharides to produce the disaccharide lactose is a -1, 4-glycosidic bond. This bond is formed between C1 of galactose and C4 of glucose, and it happens as a reduction process.
Detailed explanation-2: -Lactose is a disaccharide formed by the formation of a glycosidic bond between glucose and galactose.
Detailed explanation-3: -As a disaccharide consisting of glucose and galactose, lactose acts as an energy-carrier in milk.
Detailed explanation-4: -Lactose is a disaccharide derived from the condensation of galactose and glucose, which form a -1→4 glycosidic linkage.
Detailed explanation-5: -Lactose is composed of a molecule of galactose joined to a molecule of glucose by a -1, 4-glycosidic linkage.
