생화학적/생리학적 작용

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.

기타 정보

A concentrated solution of lactic acid is typically a mixture of lactic acid lactate and lactic acid. The concentration of this solution is approximately 90% (w/w).
