In shorthand, an Ala.-Ala nylon is a (two carbons from the amino acid backbone), but the name is misleading. Because the monomer is derived from a chiral, biological molecule, the resulting polymer behaves less like a traditional engineering plastic and more like a semi-crystalline, biodegradable protein mimic.
