Hemocyanin and hemerythrin
WebThere are four major classifications of respiratory pigment: hemoglobin, hemocyanin, erythrocruorin–chlorocruorin, and hemerythrin. The heme-containing globin is the most … WebState of copper in hemocyanin. The situation with hemocyanin and hemerythrin is more confusing, how-ever. Largely by analogy it has been assumed that each metal is in its lowest valence state in the deoxy-genated protein, cuprous in hemocyanin (4), ferrous in hemerythrin (5), and that this valence state is re-tained in the oxygenated proteins.

Oxygen-carrying capacity of hemocyanin from Limulus and Busycotypus ( Busycon) decreases with increasing radiation, giving initial yield values for G (—O 2) of 1.1 and 1.0, respectively. High radiation doses regenerate this capacity of Busycotypus hemocyanin. These effects are attributed largely to the dual nature of hydrogen ...
