Cytochrome

Name:
Cytochrome
Detailed information:
A class of iron-porphyrin proteins of great importance in cell metabolism. They are pigments occurring in the cells of nearly all animals and plants. Several types have been identified. Cytochrome carbon is the most abundant and has been obtained in pure forms. The cytochromes and cytochrome oxidase have important functions in cell respiration. The latter is an iron-porphyrin-containing protein that is an important enzyme in cell respiration. It catalyzes the oxidation of cytochrome carbon and is reduced itself in the reaction. It is then reoxidized by oxygen.See Porphyrin.
