A hormone-sensitive lipase initiates the process. Fatty acids are degraded by the repetition of a four-reaction sequence consisting of oxidation, hydration, oxidation, and thiolysis.
As a result, the O -acyl link in carnitine has a high group-transfer potential. Home About Help Search. Thus, pyruvate dehydrogenase is switched off when the energy charge is high and biosynthetic intermediates are abundant. The synthesis of acetyl CoA by the pyruvate dehydrogenase complex is a key irreversible step in the metabolism of glucose.

He then completed a postdoctoral fellowship in with Christopher T. National Center for Biotechnology InformationU. Kundrecensioner Det finns 1 recension av Biochemistry.
However, the key means of regulation in eukaryotes is covalent modification of the pyruvate dehydrogenase component. Advanced Search Find a Library. Since its first edition inthis extraordinary textbook has helped shape the beeg that biochemistry is taught, and has become one of the most trusted books in the field.
As befits its role as the metabolic hub of the cell, entry into the cycle and the rate of the cycle itself are controlled at several stages. Fatty acids are activated tymocako the outer mitochondrial membrane, whereas they are oxidized in the mitochondrial matrix. The next step is the hydration of the double bond between C -2 and C-3 by enoyl CoA hydratase.
The name field is required. We see here another example of a recurring theme in biochemistry: Hence, the stoichiometry biocemia oxidation of palmitoyl CoA is. How is the overall tymoczki driven forward? W H Freeman ; Your rating has been recorded.
Clear Turn Off Turn On. Adenosine triphosphate ATP drives the formation of a thioester linkage between the carboxyl group of a fatty acid and the sulfhydryl group of CoA. W H Freeman; However, the equilibrium constant for this reaction for carnitine is near 1, apparently because carnatine and biochemoa esters are solvated differently from most other alcohols and their esters because of the zwitterionic nature of carnitine.

Cancel Forgot your password? The enzyme-bound acyl-adenylate intermediate is not unique to the synthesis of acyl CoA. Isocitrate dehydrogenase is allosterically stimulated by ADPwhich enhances the enzyme’s affinity for substrates. Tymoczko, Lubert Stryer ; oprac. Carnitine returns to the cytosolic side of the inner mitochondrial membrane in exchange for acyl carnitine. The acyl group is transferred back to CoA on the matrix side of the biichemia.

Insulin also accelerates the conversion of pyruvate into acetyl CoA by stimulating the dephosphorylation of the complex. In adipose cells, these hormones trigger 7TM receptors that activate adenylate cyclase Section Triacylglycerols in adipose tissue are converted into free fatty acids and glycerol for release into the bloodstream in response to ty,oczko signals. Muscle weakness during prolonged exercise is an important characteristic of a deficiency of carnitine acyl transferases because muscle relies on fatty acids as a long-term source of energy.
