    Title: L-Lactic Acid
    CAS Registry Number: 79-33-4
    CAS Name: (2S)-2-Hydroxypropanoic acid
    Synonyms: L(+)-lactic acid; dextrorotatory lactic acid; d-lactic acid; sarcolactic acid; paralactic acid; Fleishmilchs?ure; L-Milchs?ure
    Molecular Formula: C3H6O3
    Molecular Weight: 90.08
    Percent Composition: C 40.00%, H 6.71%, O 53.28%
    Literature References: Occurs in small quantities in the blood and muscle fluid of man and animals. The lactic acid concn increases in muscle and blood after vigorous activity. L(+)-Lactic acid is also present in liver, kidney, thymus gland, human amniotic fluid, and other organs and body fluids. Obtained by resolution of DL-lactic acid: Purdie, Walker, J. Chem.
