CYTOCHROME


Meaning of CYTOCHROME in English

n.

Any of a group of cell protein s (hemoproteins) that serve a vital function in the transfer of energy within cells.

Hemoproteins are linked to a nonprotein, iron-bearing component (a heme group), which can undergo the reversible oxidation-reduction reaction s that yield energy for the cell. Cytochromes are subdivided into three classes depending on what wavelengths of light they absorb. At least 30 different cytochromes have been identified.
