it is a structural carbohydrate which forms their exoskeleton. exoskeleton is the external skeleton that supports and protects an animal's body.
Chitin is a crucial structural carbohydrate found in arthropods, forming their protective exoskeleton and enabling growth through molting. It consists of nitrogen-containing polysaccharide units, specifically N-acetyl-β-D-glucosamine. Additionally, chitin also plays a significant role in the cell walls of fungi, indicating its broad biological importance.
