2.1: About Carbonic Anhydrase - Chemistry LibreTexts

WebBicarbonate (HCO 3−) has a pK a of 10.3 with carbonate (CO 32− ), far further from physiologic pH (7.35–7.45), and so it is more likely to accept a proton than to donate one, but it is also far less likely for it to do either, thus bicarbonate will be the major species at physiological pH.
