Webbicarbonate. CO 2 (aq) + OH-= HCO 3 - (1) In biological systems the hydration of carbon dioxide is catalyzed by carbonic anhydrase a Zn-containing enzyme. Only a small portion of the aqueous carbon dioxide exists as carbonic acid. However, in most H 2 CO 3 * (as defined below) is used to represent solution carbonates. * H 2C O 3 =H 2 C 3 + CO 2 ... WebThe Henderson–Hasselbalch equation was developed independently by the American biological chemist L. J. Henderson and the Swedish physiologist K. A. Hasselbalch, for relating the pH to the bicarbonate buffer system of the blood (see below). In its general form, the Henderson–Hasselbalch equation is a useful expression for buffer calculations.
