WebHemocyanin, or haemocyanin, is any of a group of copper -containing respiratory proteins that serve an oxygen -carrying function in the blood of some arthropods and most mollusks, similar to the role of hemoglobin found in the blood of vertebrates. Hemocyanins (also spelled haemocyanins and abbreviated Hc) are proteins that transport oxygen throughout the bodies of some invertebrate animals. These metalloproteins contain two copper atoms that reversibly bind a single oxygen molecule (O2). They are second only to hemoglobin in … Meer weergeven Hemocyanin was first discovered in Octopus vulgaris by Leon Fredericq in 1878. The presence of copper in molluscs was detected even earlier by Bartolomeo Bizio in 1833.
