Question
The chitinous exoskeleton of arthropods is formed by the polymerisation of
-
Keratin sulphate and chondraitin sulphate
-
D-glucosamine
-
N-acetyl glucosamine
-
lipoglycans
Solution
C.
N-acetyl glucosamine
The chitinous exoskeleton of arthropods is formed by the polymerisation of N-acetyl glucosamine, which is a derivative of glucose. It is also a characteristic component of the cell wall of fungi, the radulae of molluscs and the beaks and internal shells of cephalopods including squid and octopuses.
