English
[edit]
Etymology
[edit]From chloro- + cruor + -in (see also cruorin). Named by British zoologist Ray Lankester in 1868.
Noun
[edit]chlorocruorin (uncountable)
- (biochemistry, organic chemistry) A green respiratory pigment found in many annelids.
- 1966, David Keilin, edited by Joan Keilin, 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, 1933 a).
- 2003, Ashok Kumar, Animal Physiology, Discovery Publishing House, page 192:
- The affinity of chlorocruorin for oxygen is equivalent to the haemoglobin. It is interesting that within the same family of worms like [S]abellidae, [S]erpulidae and [A]mphotritidae same[sic] species have chlorocruorin while others have haemoglobin.
- 1992, N. B. Terwilliger, Chapter 8: Molecular Structure of the Extracellular Heme Proteins, Ch. P. Mangum (editor), Advances in Comparative & Environmental Physiology 13: Blood and Tissue Oxygen Carriers, Springer-Verlag, 1992 softcover reprint, page 203,
- It was earlier thought that chlorocruorin was very different from hemoglobin based on a subunit structure with a mass of 34-35 kDa (Antonini et al. 1962; Guerratore and Zito 1977). […] Some writers have questioned the value of drawing a distinction between the chlorocruorins and hemoglobins, especially from an evolutionary point of view (Mangum 1985; see also Toulson, Chap. 9, this Vol.). The visual phenomenon of green blood has perhaps led to a stronger distinction between chlorocruorin and hemoglobin than warranted.
