Carbon dioxide form carbamate by reaction of carbonic acid with N-terminal in Bohr Effect?
In the tissues, CO2 reacts with water to form carbonic acid in the presence of the enzyme carbonic anhydrase. This carbonic acid can form a salt with Hg by reacting with its N terminal forming what is called carbamates. Also, carbonic acid dissociates spontaneously in the tissues into carbonates and protons (H+ ions). The protons can be carried on some amino acids. (Review question # 11).
