Lactic Acid and Sodium Hydroxide

CH3CHOHCOOH + NaOH → CH3CHOHCOONa + H2O

概要

Lactic acid, produced during anaerobic metabolism in muscles, reacts with sodium hydroxide to form sodium lactate and water. Lactic acid has a pKa of 3.86 and exists in L and D enantiomeric forms. L-lactic acid accumulation causes the burning sensation during intense exercise.
