By agreement with the publisher, this book is accessible by tymocczko search feature, but cannot be browsed. 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 hydration of enoyl CoA bdrg a prelude to the second oxidation reaction, which converts the hydroxyl group at C -3 into a keto group and generates NADH.
The increased level of cyclic AMP then stimulates protein kinase Awhich activates the lipases by phosphorylating them. He then completed a postdoctoral fellowship in with Christopher T.
These diseases illustrate that the impaired flow of a metabolite from one compartment of a cell to another can lead to a pathological condition. We shall return to this point shortly in considering how unsaturated fatty acids are oxidized. Because pyruvate dehydrogenase is always phosphorylated and thus inactive, glucose is processed to lactic acid.
You may have already requested this item. Two-carbon units are sequentially removed from the carboxyl end of the fatty acid.
Finally, the translocase returns carnitine to the cytosolic side in exchange for an incoming acyl carnitine.
Clear Turn Off Turn On. Subsequent work demonstrated that they are activated before they enter the mitochondrial matrix.
The shortened acyl CoA then undergoes another cycle of oxidation, starting with the reaction catalyzed by acyl CoA dehydrogenase Figure In this process, triacylglycerols are degraded to fatty acids and glycerol, which are released from the adipose tissue and transported to the energy-requiring tissues.

This reaction, which is catalyzed by carnitine acyltransferase II carnitine palmitoyl transferase IIis simply the reverse of the reaction that takes place in the cytosol.
How is the overall reaction driven forward?
Biochemia : Jeremy M. Berg :
The pyruvate dehydrogenase component is also regulated by covalent modification. Fatty acyl chains containing from 12 to 18 carbon atoms are oxidized by the long-chain acyl Biocbemia dehydrogenase. Please enter your name.
Some aspects of this enzyme’s control are like those of the pyruvate dehydrogenase complex, as might be expected from the homology of the two enzymes. W H Freeman; Third, the fatty acids are broken down in a step-by-step fashion into acetyl CoAwhich is then processed in the ttymoczko acid cycle. It offers exceptionally clear writing, innovative graphics, coverage of the latest research techniques and advances, and a signature emphasis on physiological and medical relevance.
First, the lipids must be mobilized. The synthesis of acetyl CoA by the pyruvate dehydrogenase tyjoczko is a key irreversible step in the metabolism of glucose. Carnitine returns to the cytosolic side of the inner mitochondrial membrane in exchange for acyl carnitine. Amino acids are activated for protein synthesis by a similar mechanism Section Write a review Rate this item: Tymoczko, Lubert Stryer ; oprac.

Adenosine triphosphate ATP drives the formation of a thioester linkage between the carboxyl group of a fatty acid and the sulfhydryl group of CoA. The focus thmoczko his research has been on steroid receptors, ribonucleoprotein particles, and proteolytic processing enzymes. W H Freeman ; We see here another example of a recurring theme in biochemistry: Peripheral tissues gain access to the lipid bberg reserves stored in adipose tissue through three stages of processing.
