Webcytochrome, any of a group of hemoprotein cell components that, by readily undergoing reduction and oxidation (gain and loss of electrons) with the aid of enzymes, serve a vital function in the transfer of energy within cells. Hemoproteins are proteins linked to a nonprotein, iron-bearing component. It is the iron (heme) group attached to the protein … Cytochrome c has been used to detect peroxide production in biological systems. As superoxide is produced, the number of oxidised cytochrome c increases, and reduced cytochrome c decreases. However, superoxide is often produced with nitric oxide. In the presence of nitric oxide, the reduction of cytochrome c is inhibited. This leads to the oxidisation of cytochrome c to cyto… marshalls athol mass

WebSep 5, 2024 · A cytochrome is a protein involved in electron transfer that contains a heme group. The heme groups alternate between ferrous (Fe2+) and ferric (Fe3+) states during the electron transfer. Cytochromes are redox-active proteins containing a heme, with a central iron (Fe) atom at its core, as a cofactor. They are involved in electron transport chain and redox catalysis. They are classified according to the type of heme and its mode of binding. Four varieties are recognized by the International Union of … See more Cytochromes were initially described in 1884 by Charles Alexander MacMunn as respiratory pigments (myohematin or histohematin). In the 1920s, Keilin rediscovered these respiratory pigments and named them … See more The heme group is a highly conjugated ring system (which allows its electrons to be very mobile) surrounding an iron ion. The iron in cytochromes usually exists in a ferrous (Fe ) and a ferric (Fe ) state with a ferroxo (Fe ) state found in catalytic intermediates. … See more • Scripps Database of Metalloproteins • Cytochromes at the U.S. National Library of Medicine Medical Subject Headings (MeSH) See more
