The methoxatin semiquinone: a pulse radiolysis study. 1986

M Faraggi, and R Chandrasekar, and R B McWhirter, and M H Klapper

Methoxatin is a novel o-quinone found in bacterial dehydrogenases and mammalian plasma amine oxidase. This is the first report of the redox potential and spectrum of the 1-electron reduced methoxatin semiquinone obtained by the method of pulse radiolysis in aqueous solution.

D007700 Kinetics The rate dynamics in chemical or physical systems.
D008433 Mathematics The deductive study of shape, quantity, and dependence. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed) Mathematic
D010084 Oxidation-Reduction A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471). Redox,Oxidation Reduction
