Chitin is another structural carbohydrate. They all serve the same purpose of protecting and maintaining structure, but they are very different molecules.
What are cell walls of plants and fungi made of? Plant cell walls are composed of cellulose fibres that are connected by hemicellulose fibres and embedded in a matrix of pectin.
