Carbonic anhydrase enzyme found in red blood cells. It place important role in the respiration by transporting co2 transport in the blood
Water and carbon dioxide from the interestial fluid diffuse in to epithelial cells with in these cells carbonic anhydrase convert in bicarbonate and hydrogen ion.

Cobalt(II) can substitute for Zn(II) in carbonic anhydrase and other proteins in which the metal ion acts as a Lewis Acid. The coordination chemistry of Co2+ is very similar to that of Zn2+, and the two ions have almost identical radii. Cobalt ion is an excellent structural and functional model for studies of a protein’s zinc binding sites. The advantage of Co(II)–substituted proteins is that they exhibit d → d transitions in the visible region of the electromagnetic spectrum, as...
