The mollusk oxygen-transport pigment is what
WebDec 11, 2015 · Mollusk gills are called ctenidia, and they are made up of a series of thin filaments of tissue that resemble the teeth of a comb. These filaments absorb oxygen … WebAbstract. Among the mollusca, hemocyanins are known to serve as oxygen transport pigments in the gastropods, cephalopods, and amphineura. No bivalve has been shown to have hemocyanin; instead, a number use hemoglobin for oxygen transport. All known molluscan hemocyanins share some common features of molecular architecture.

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 frequency … See more 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. Hemocyanins are found in the Mollusca See more Hemocyanin is homologous to the phenol oxidases (e.g. tyrosinase) since both proteins have histidine residues, called "type 3" copper-binding coordination centers, as do the … See more Spectroscopy of oxyhemocyanin shows several salient features: 1.
