Lactic Acid and Sodium Hydroxide

CH3CHOHCOOH + NaOH → CH3CHOHCOONa + H2O

Descripción general

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.

Ejemplo cotidiano

The muscle burn during intense exercise is caused by lactic acid accumulation. Sodium lactate is used in IV fluids (Ringer's lactate) for rehydration.

Importancia industrial

El lactato de sodio se usa en la conservación de alimentos, en la solución de Ringer intravenosa, en cosméticos como humectante y como precursor del ácido poliláctico (PLA) biodegradable.
