Chitin sounds like a type of insect, but it's actually a substance that helps form what part of an insect's body?

Not to get all "sciency," but chitin is "a fibrous substance consisting of polysaccharides and forming the major constituent in the exoskeleton of arthropods and the cell walls of fungi." So chitin basically makes up the hard shell on some insects.
