Which of the following glycosidic linkage found in maltose?
A
Glucose (
B
Glucose (
C
Galactose (
D
Glucose (
Explanation: 

Detailed explanation-1: -Maltose (“malt sugar”) arises from the reaction of two glucose molecules by a -1, 4-glycosidic 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 a disaccharide which is formed by two units of glucose molecules linked by a glycosidic bond. The bond is formed between the C1 of one glucose with the C4 of other glucose molecule.

Detailed explanation-4: -Amylose is an unbranched version of starch that only contains alpha-1, 4-glycosidic bonds.
