DEFINITION:
- lactic acid
-
A metabolic intermediate involved in many biochemical processes; it is the end product of glycolysis, which provides energy anaerobically in skeletal muscle during heavy exercise, and it can be oxidized aerobically in the heart for energy production or can be converted back to glucose (gluconeogenesis) in the liver. Moderate elevations of blood lactate occur during heavy exercise; severe elevations (lactic acidosis) can occur in diabetes mellitus and in genetic deficiencies of enzymes involved in gluconeogenesis. Lactate is also the end product of fermentation in several bacterial species.
