Scientists have postulated that a highly-deacetylated form of it could increase crop yields, and approximately 10 gigatons of it are produced each year naturally.

Consisting of repeated N-acetyl-glucosamine residues linked together by beta-1-4 glycosidic bonds, its amide bonds make it stronger and more stable than cellulose, the only molecule which is more abundant than it on Earth.  From the Greek word for "tunic," FTP, name this strong polysaccharide found in the exoskeletons of all insects and crustaceans as well as in the cell wall of fungi.
