Question

what is chitin what is its function​

Answer 1

Chitin ₙ is a long-chain polymer of N-acetylglucosamine, an amide derivative of glucose. The second most abundant polysaccharide in nature, it is a primary component of cell walls in fungi, the exoskeletons of arthropods such as crustaceans and insects, and the radulae, cephalopod beaks and gladii of molluscs.

In mathematics, a function is a binary relation between two sets that associates each element of the first set to exactly one element of the second set. Typical examples are functions from integers to integers, or from the real numbers to real numbers.

Explanation:

Chitin is the main ingredient in the exoskeletons of arthropods and crustaceans and is also in the cell walls of fungi. That means everything from beetles, spiders, and butterflies to lobsters, crabs, and shrimp have some chitin in their protective armors.
