Lactic acid (IUPAC systematic name: 2-hydroxypropanoic acid), also known as milk acid, is a chemical compound that plays a role in several biochemical processes. Lactic acid is chiral and has two optical isomers. One is known as L-(+)-lactic acid or (S)-lactic acid and the other, its mirror image, is D-(−)-lactic acid or (R)-lactic acid. L-(+)-Lactic acid is the biologically important isomer. Application: can be used to produce serial products or widely used in food, vintage, beverage, drugs, polymerization, textile, leather, tobacco, feed, plastic chemicals, pesticide, polymer solution and other industry.
