L(+)-Lactic acid Usage And Synthesis |
Chemical Properties | Crystalline Solid |
Uses | Occurs in small quantities in the blood and muscle fluid of man and animals. The lactic acid concentration increases in muscle and blood after vigorous activity. L-(+)-Lactic acid is also present in liver, kidney, thymus gland, human amniotic fluid, and o |
Definition | ChEBI: An optically active form of lactic acid having (S)-configuration. |
Purification Methods | Purify lactic acid by fractional distillation at 0.1mm pressure, followed by fractional crystallisation from diethyether/isopropyl ether (1:1, dried with sodium). [Borsook et al. J Biol Chem 102 449 1933.] The solvent mixture, *benzene/diethylher (1:1) containing 5% pet ether (b 60-80o) has also been used. [Brin Biochemical Preparations 3 61 1953, Beilstein 3 IV 633.] |
