Q. Starch is converted to maltose in the digestive system by the enzyme

A
Maltose
B
Amylose
C
Lipase
D
Peptidase
Solution:
  • Maltose, also known as maltobiose or malt sugar, is a disaccharide formed from two units of glucose joined with an a bond. In the isomer isomaltose, the two glucose molecules are joined with an a bond.
  • Amylose is a polysaccharide made of a-D-glucose units, bonded to each other through a(1?4) glycosidic bonds. It is one of the two components of starch, making up approximately 20-30%. Amylose is more soluble in water than the other component amylopectin.

  • A lipase is any enzyme that catalyzes the hydrolysis of fats. Lipases are a subclass of the esterases. Lipases perform essential roles in digestion, transport and processing of dietary lipids in most, if not all, living organisms.

  • A protease is an enzyme that performs proteolysis: protein catabolism by hydrolysis of peptide bonds.
