beta-Oxidation of the coenzyme A esters of vaccenic, elaidic, and petroselaidic acids by rat heart mitochondria. 1979

L D Lawson, and F A Kummerow

Rates of beta-oxidation of the coenzyme A esters of vaccenic, elaidic, and petroselaidic acids as well as their respective cis isomers by rat heart mitochondria were measured and compared. At all concentrations studied, vaccenoyl-CoA was oxidized more rapidly than elaidoyl-CoA, but more slowly than oleoyl-CoA except at high substrate concentrations. All trans octadecenoyl-CoA esters were oxidized at a slower rate than their respective cis or saturated isomers. Oxidation rates decreased as the double bond approached the carboxyl-end.

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
