젖산과 수산화나트륨
CH3CHOHCOOH + NaOH → CH3CHOHCOONa + H2O
개요
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.
참여 물질
일상 속 예시
The muscle burn during intense exercise is caused by lactic acid accumulation. Sodium lactate is used in IV fluids (Ringer's lactate) for rehydration.
