Chitin is a robust, linear polysaccharide composed of N-acetylglucosamine units, serving primarily as a major structural biopolymer in nature. Structurally, it provides rigid support, forming the foundational material for the exoskeletons of various invertebrates and constituting a key component of fungal cell walls. Beyond its biological roles, chitin is highly valued in materials science due to its strength, lightweight nature, and inherent biocompatibility. This has led to its application in the creation of biodegradable materials, composite structures, and sophisticated scaffolds used in various technological fields.
