2] in the mixture was measured at 550 nm by estimating the oxidation product of ferrocytochrome
Hoppel, "Decreased activities of ubiquinol: ferricytochrome c oxidoreductase (complex III) and ferrocytochrome
c:oxygen oxidoreductase (complex IV) in liver mitochondria from rats with hydroxycobalamin[c-lactam]-induced methylmalonic aciduria," The Journal of Biological Chemistry, vol.
This colorimetric assay is based on an observation of the decrease in absorbance at 550 nm of ferrocytochrome
c caused by its oxidation to ferricytochrome c by cytochrome c oxidase.
There are three kinds of reductases that reduce trivalent iron of methemoglobin, NADH is the coenzyme of the first one, NADPH--the second one, and the third one acts with participation of ferrocytochrome [b.
The reduction of methemoglobin by ferrocytochrome [b.

We determined total superoxide dismutase (SOD) activity from the rate of inhibition of the oxidation of 20 [micro]M ferrocytochrome
c at 550 nm in a reaction mixture consisting of 50 [micro]M phosphate buffer (pH 7.

Andrew McCammon and his colleagues at the University of Houston and Peter Wolynes at the University of Illinois in Urbana-Champaign simulated the molecular motions of atomic groups in the molecule ferrocytochrome
C using quantum dynamic principles and found "significant differences" in how the stretching of chemical bonds and the oscillation of chemical groups was modeled.
depending on the electron flux level through the respiratory chain, that is, on the concentration of mitochondrial ferrocytochrome
c, and particularly under low [O.
