-Synthesis:
+At the molecular level, PLA is an '''aliphatic polyester''' composed of repeating '''ester linkages''' derived from lactic acid (2-hydroxypropanoic acid). The basic repeating unit has the structure:
-* Condensation of Lactic Acid (hence the name) with the loss of water.
+[-O–CH(CH₃)–CO–]ₙ
-[[File:PLA Reaction.jpg|thumb|The reaction formula for PLA through condensation of Lactic Acid or ring-opening polymerization of lactide.]]
+Lactic acid exists in two mirror-image forms, '''L-lactic acid''' and '''D-lactic acid'''. As a result, PLA can be synthesized as poly(L-lactic acid) (PLLA), poly(D-lactic acid) (PDLA), or a mixture of both. The combination of these enantiomers can form '''stereocomplexes''', which have higher melting points and better thermal stability than pure PLLA or PDLA.
