Is chitin a carbohygen

Chitin is not classified as a carbohydrate; rather, it is a polysaccharide made up of N-acetylglucosamine units. It serves primarily as a structural component in the exoskeletons of arthropods and the cell walls of fungi. While it shares some similarities with carbohydrates, such as being a polymer of sugar molecules, its nitrogen-containing groups set it apart. Therefore, it is more accurately described as a nitrogenous polysaccharide.
