What Wikipedia says

Polylactic acid, also known as poly(lactic acid) or polylactide (PLA), is a plastic material. As a thermoplastic polyester (or polyhydroxyalkanoate) it has the backbone formula (C3H4O2)n or [–C(CH3)HC(=O)O–]n. PLA is formally obtained by condensation of lactic acid C(CH3)(OH)HCOOH with loss of water (hence its name).
