Chitin



This polysaccharide, chitin, has nitrogen that specifically makes up the cell wall of fungi and the exoskeleton of organisms such as beetles. This picture exhibits a ladybug. The outer shell, the exoskeleton, of the ladybug has chitin. Otherwise, the ladybug would not have its tough shell. Interestingly, chitin is a carbohydrate.
