Carbonic Acid Dissociation (Blood Buffer)

H2CO3 ⇌ HCO3− + H+

개요

The carbonic acid/bicarbonate buffer system is the primary blood buffer maintaining pH between 7.35 and 7.45. Carbon dioxide dissolves in blood to form carbonic acid, which dissociates to bicarbonate and hydrogen ions. The enzyme carbonic anhydrase catalyzes the CO₂ hydration. Disruption causes acidosis or alkalosis.
