Question

Chitin is a

• A. homopolymer made up of N-acetyl glucosamine
• B. heteropolymer made up of N-acetyl glucosamine and N-acetyl galactosamine
• C. homopolymer made up of N-acetyl galactosamine
• D. homopolymer made up of N-acetyl fructosamine

Answer 1

The correct option is A homopolymer made up of N-acetyl glucosamine

Homopolymers are made from the polymerization of identical monomers whereas heteropolymers are made from the polymerization of two or more different monomers. Exoskeletons of arthropods have a complex polysaccharide called chitin. It is a homopolymer made up of N-acetyl glucosamine.
