Chemistry Question on Biomolecules
Among the following, which one is a disaccharide?
A
Glucose
B
Glycogen
C
Maltose
D
Starch
Answer
Maltose
Explanation
Solution
Maltose is a disaccharide composed of two glucose molecules linked together by a glycosidic bond. It is commonly found in germinating seeds and is produced during the breakdown of starch by the enzyme amylase.
Glucose is a monosaccharide , which means it consists of a single sugar molecule.
Glycogen is a polysaccharide , which is a complex carbohydrate composed of multiple glucose units linked together.
Starch is also a polysaccharide composed of glucose units and serves as a storage form of energy in plants.
Therefore, the correct option is (C): Maltose.
