DL-Lactic acid Usage And Synthesis

Uses

DL-Lactic Acid 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.

Definition

ChEBI: 2-hydroxypropanoic acid is a 2-hydroxy monocarboxylic acid that is propanoic acid in which one of the alpha-hydrogens is replaced by a hydroxy group. It has a role as a Daphnia magna metabolite and an algal metabolite. It is functionally related to a propionic acid. It is a conjugate acid of a lactate.
