Answer: D. Other functions performed include O 2 storage, CO 2 transport, and transportation of substances other than respiratory gases. chlorocruorin (uncountable) (biochemistry, organic chemistry) A green respiratory pigment found in many annelids. It is a metalloprotein with the metal being iron (Fe ++); the metalloporphyrin is similar to heme of haemoglobin except that one vinyl (CH = CH 2) group is replaced by formyl (0=CH) group in chlorocruorin (Fig. Hemoglobins predominate in young individuals of the genus Serpula, while chlorocruorins predominate in the adults. Respiratory pigments Explanation. 1966, David Keilin, Joan Keilin (editor), The History of Cell Respiration and Cytochrome, University of Cambridge, page 174, Later it was shown that the α-bands of the pyridine haemochromogens of both cytochrome a and chlorocruorin resemble each other closely (Keilin, … It is also found in oxy­genated and reduced forms. Chlorocruorin is an oxygen binding hemeprotein present in the blood plasma of many annelids, particularly certain marine polychaetes. rin …   English syllables, chlorocruorin — ˌ ̷ ̷ ̷ ̷ˈkrüərə̇n noun ( s) Etymology: chlor + cruorin (old name for hemoglobin), from Latin cruor blood) + English in more at raw : a green iron containing respiratory pigment related chemically to hemoglobin and found in the blood of certain… …   Useful english dictionary, annelid — /an l id/, n. 1. any segmented worm of the phylum Annelida, including the earthworms, leeches, and various marine forms.

Blood containing chlorocruorins is red when discharged from the blood vessels and green when diluted. Most molluscs and arthropods contain hemocyanin, such as … There are four major classifications of respiratory pigment: hemoglobin, hemocyanin, chlorocruorin, and hemerythrin. Its affinity for oxygen is weaker than that of most hemoglobins.

It is chemically similar to haemo­globin, and is only found dissolved in the blood of certain marine annelid worms. In the blood plasma the chlorocruorins are in a dissolved state and, like erythrocruorins, have a high molecular weight (2,800,000). Hemoglobin, the most common pigment, is present in most free-moving and some sedentary polychaetes and in most oligochaetes and leeches. Continuing to use this site, you agree with this. [1][2] They contain heme, in which the vinyl group (CH=CH) of protoporphyrin in position 2 is replaced by the formyl group (CHO). a green respiratory pigment that replaces hemoglobin in some polychaetes, specifically, the worms of the families Sabellidae, Serpulidae, Chlorhaemidae, and Ampharetidae.
