blood pigments

blood pigments

the complex protein molecules found in blood and other tissues, which contain metal atoms in their structure. Such pigments have a high affinity for oxygen, functioning in oxygen transport, e.g. HAEMOGLOBIN in vertebrates (containing iron) and HAEMOCYANIN in molluscs and arthropods (with copper), and in oxygen storage within tissues, e.g. MYOGLOBIN (iron) found in muscle cells. See OXYGEN DISSOCIATION CURVE.

At the same time metabolic rate is reduced at lower temperatures, with the consequence that in some species blood pigments may be less important (for hemocyanin, see Mauro and Mangum, 1982b; Burnett et al.
However, the capacity of their blood pigment, hemocyanin, for carrying oxygen is constrained by the low concentration of an extracellular pigment.
Low-molecular-weight organic substances that contribute to blood pigment function in vertebrates or crustaceans are not found in this group.
Comparison of hemocyanin oxygen binding in cephalopods of different metabolic rates and from various latitudes should show how hemocyanin oxygen transport has adapted to different temperature regimes at various levels of metabolic activity and how blood pigment function contributes to the oxygen limitation of thermal tolerance.
