LACTIC ACID

Lactic acid is a carboxylic compound (carboxylic acid) containing a hydroxyl group, with the chemical formula C3H6O3, which plays a role in a variety of physiological processes. Its industrial product is a colourless to light yellow liquid, and its pure product is a colourless and odourless liquid, which is hygroscopic and miscible with water, ethanol and glycerol. Lactic acid belongs to α-hydroxy acid (AHA) in aqueous solution, its carboxyl group releases a proton and produces lactate ion CH3CH(OH)COO-, the aqueous solution is acidic, pKa = 3.85. Recent studies have found that lactic acid regulates immune, angiogenic and even brain functions (e.g. 'exercise euphoria' may be relevant). Lactic acid is not the main cause of muscle soreness (delayed soreness is due to micro-injury), but its accumulation may inhibit enzyme activity by lowering pH, which may cause transient fatigue.

Lactic acid production during exercise
Anaerobic metabolism: when exercise intensity exceeds the aerobic threshold (e.g., sprinting, weight lifting), muscle cells produce energy rapidly through glycolysis, at which time pyruvate is converted to lactate under the action of **lactate dehydrogenase (LDH)**, while NAD⁺ is regenerated to maintain energy supply. 'Lactate threshold": the intensity of exercise when blood lactate concentration reaches 4 mmol/L, an important indicator of endurance training. The shift in perception of lactic acid from 'metabolic waste' to 'multifunctional molecule' reflects advances in exercise science. Proper use of its properties can optimise training and health management.
