We can now calculate the energy yield derived from the oxidation of a fatty acid. Triacylglycerols Are Hydrolyzed by Cyclic AMP-Regulated Lipases The initial event in the utilization of fat as an energy source is the hydrolysis of triacylglycerols by lipases, an event referred to as lipolysis.

Carnitine Carries Long-Chain Activated Fatty Acids into the Mitochondrial Matrix Fatty acids are activated on the outer mitochondrial membrane, whereas they are oxidized in the mitochondrial matrix.

The synthesis of acetyl CoA by the pyruvate dehydrogenase complex is a key irreversible step in the metabolism of glucose.

The increased level of cyclic AMP then stimulates protein kinase Awhich activates the lipases by phosphorylating them. The medium-chain acyl CoA dehydrogenase oxidizes fatty acyl chains having from 14 to 4 carbons, whereas the short-chain acyl CoA dehydrogenase acts only on 4- and 6- carbon acyl chains. The focus of his research has been on steroid receptors, ribonucleoprotein particles, and proteolytic processing enzymes.

The acyl group is transferred back to CoA on the matrix side of the membrane. Semmelhack and was awarded the Everett S. The oxidative decarboxylation of pyruvate to acetyl CoA commits the carbon atoms of glucose to two principal fates: In fact, the equilibrium constant for the sum of these reactions is close to 1.

Another motif recurs in this activation reaction. Create lists, bibliographies and reviews: The first reaction in each round of degradation is the oxidation of acyl CoA by an acyl CoA dehydrogenase to give an enoyl CoA with a trans double bond between C -2 and C Thus, pyruvate dehydrogenase is switched off when the energy charge is high and biosynthetic intermediates are abundant.

This oxidation is catalyzed by l hydroxyacyl CoA dehydrogenasewhich is specific for the l isomer of the hydroxyacyl substrate. The seventh edition has been updated throughout, including many new advances on genetic regulation, and revamped coverage of the integration of metabolism in the context of diet and obesity.

One high-transfer-potential compound is cleaved between PP i and AMP and one high-transfer-potential compound is formed the thioester acyl CoA.

Shanoff Young Investigator Research Award. Please verify that you are not a robot. National Center for Biotechnology InformationU. In turn, glucose is funneled into pyruvate.

By agreement with the publisher, this book is accessible by the search feature, but cannot be browsed. Two-carbon units are sequentially removed from the carboxyl end of the fatty acid.
