Definitions for hemocyaninˌhi məˈsaɪ ə nɪn
This page provides all possible meanings and translations of the word hemocyanin
a blue copper-containing respiratory pigment (a metalloprotein) found in most molluscs, and some arthropods
Hemocyanins 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. They are second only to hemoglobin in frequency of use as an oxygen transport molecule. Unlike the hemoglobin in red blood cells found in vertebrates, hemocyanins are not bound to blood cells but are instead suspended directly in the hemolymph. Oxygenation causes a color change between the colorless Cu deoxygenated form and the blue Cu oxygenated form.
