The nature of lactic acid

Lactate (Lactic Acid) scientific name 2-hydroxy-propionic acid (2-Hydro ~ Pmp ~ eic Acid) The molecular formula C3H603, structural formula CH3CHOHCOOH, relative molecular mass of 9O. O8. Because of its molecule containing an asymmetric carbon atom, and therefore has optical activity, L-lactic acid Right-handed, when L-lactic acid and D-lactic acid when mixed in equal proportions, which has become a milk racemic DL Acids. L-lactic acid is fully compatible with water, but does not crystallize. Lactic acid concentration above 60% with Strong buffered lactic acid  Pure anhydrous acid is a white crystal, mp 16.8 ℃, boiling Point of 122 ℃ (2kPa), the relative density of 1.24. L-lactic acid molecule containing a hydroxyl group and carboxyl Group, it is the ability automatic magnessium lactate  dehydration can aggregate into poly-L-lactic acid. L a general industrial use Lactic acid content of 50% to 80%, food and pharmaceutical industries with L-lactic acid content of 8O%-9O%.
