A distinct family of cytochromes is the cytochrome P450 family, so named for the characteristic Soret peak formed by absorbance of light at wavelengths near 450 nm when the heme iron is reduced (with sodium dithionite) and complexed to carbon monoxide. These enzymes are primarily involved in … See more 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 … See more Cytochromes were initially described in 1884 by Charles Alexander MacMunn as respiratory pigments (myohematin or histohematin). In … See more • Scripps Database of Metalloproteins • Cytochromes at the U.S. National Library of Medicine Medical Subject Headings (MeSH) 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 WebMay 7, 2024 · To measure the visible absorbance spectra for hemoglobin (Sigma H-7379), myoglobin (Sigma M-0630), and cytochrome c (Sigma C-3131), solutions of each were prepared in water at a concentration of …

WebUV-spectra of cytochrome c-typical spectra of cytochrome c with three absorbance peaks of its reduced form (Fe 2+ ) at 550 nm, 521 and 414 nm (solid line) and two peaks of its oxidized form (Fe... Webabsorption spectrum of cytochrome c changes with its oxidation/reduction state. Upon reduction a sharp absorption peak is observed at 550 nm. The reduction of cytochrome c is monitored by the increase of cytochrome c absorbance at 550nm. Note that the monitored wavelength is critical, and the deviation must be 2 nm or less.
