respiratory pigment

Any pigment such as hemoglobin, myoglobin, or cytochrome that has a part in the metabolism of oxygen within the body.See also: pigment

respiratory pigment

a substance present in blood, usually in the corpuscles or the plasma, that combines reversibly with oxygen and acts as a store for it. Oxygen is taken up in a respiratory organ such as the lung, and blood gives up oxygen where it comes into contact with oxygen-deficient tissues. Examples of such pigments include HAEMOGLOBIN, HAEMOCYANIN, CHLOROCRUORIN, HAEMERYTHRIN. See also OXYGEN DISSOCIATION CURVE.
