Application

Lactic acid is used as a reagent in organic synthesis (in the manufacture of adhesives). It is used in the leather, textile, and tanning industries. It may be used as a plasticizer, a catalyst, or an acidifying agent. Lactic acid has even been used as a flavoring agent in the manufacture of tobacco products.

Biochem/physiol Actions

In animals, lactic acid is a metabolic compound produced by proliferating cells and during anaerobic conditions such as strenuous exercise. Lactic acid can be oxidized back to pyruvate or converted to glucose via gluconeogenesis. Lactic acid is preferentially metabolized by neurons in several mammal species and during early brain development. D-lactate was utilized four times more slowly than L-lactate, but both isomers are absorbed at the same rate from the intestine.

d-Lactic and l-lactic acids were simultaneously determined by means of a column-switching high-performance liquid chromatography (HPLC) with fluorescence detection. As a fluorescence reagent, 4-nitro-7-piperazino-2,1,3-benzoxadiazole (NBD-PZ) was employed for the fluorescence derivatization of lactic acid. The proposed HPLC system adopted both
