Uses
D-(+)-Propionate is a cyclic diester of lactic acid, a by-product that is produced by muscle cells and red blood cells when the body breaks down carbohydrates for energy at low oxygen levels. A suitable catalyst can be used to polymerise the propylene cross ester into polylactic acid, resulting in a material with useful properties.
