Figs. 2 and 4 were obtained … Webboth microsomal cytochrome P-450 content and in micro-somal spectral binding of hexobarbital or aniline produced by the 0.84 mg/ kg cadmium dose were not elicited in the rats pretreated with the low cadmium dose. The 0.21 mg/kg cadmium dose produced an increase (370%) in the cadmium-binding capacity as well as an increase (395%) in total

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 the cytochromes, or “cellular pigments”. He classified these heme proteins on the basis of the position of … 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 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 … See more • Scripps Database of Metalloproteins • Cytochromes at the U.S. National Library of Medicine Medical Subject Headings (MeSH) See more WebMay 1, 1976 · Tin cytochrome c shows visible absorption maxima at 536 and 574 nm and Soret absorption at 410 nm. Unlike iron cytochrome c in which the emission spectrum of the porphyrin is almost completely quenched by the central metal, the zinc and tin derivatives of cytochrome c are both fluorescent and phosphorescent.
