WebThe synthesis of the activated form of acetate (acetyl-CoA) is carried out in an ATP-dependent process: (a) The ∆G ’o for the hydrolysis of acetyl-CoA to acetate and CoA is - 32.2 kJ/mol and that for hydrolysis of ATP to AMP and PPi is - 30.5 kJ/mol. Calculate ∆G ’o for the ATP-dependent. synthesis of acetyl-CoA. WebHydrolysis of thioesters The acyl group of a thioester can be transferred to a water molecule in a hydrolysis reaction, resulting in a carboxylate. An example of thioester …

WebIn addition, the lack of oxaloacetate stops the pointless hydrolysis of the thioester in acetyl-CoA. This happens when there is no oxaloacetate present. This hydrolysis would ordinarily result in the release of energy; however, since the reaction cannot take place in the absence of oxaloacetate, the energy does not become available. WebAcetyl CoA is used to create lipids, triglycerides, steroid hormones, cholesterol, and bile salts. Lipolysis is the breakdown of triglycerides into glycerol and fatty acids, making them easier for the body to process.

WebAcetyl-CoA can be synthesized in two ways. ATP, adenosine triphosphate; AMP, adenosine monophosphate. In chloroplasts, photosynthesis provides the NADPH required for the biosynthesis of fatty acids, while in leucoplasts it originates from the oxidation of glucose 6-phosphate via the oxidative pentose phosphate pathway ( Fig. 6.21 ). WebThe synthesis of the activated form of acetate (acetylCoA) is carried out in an ATP-dependent process: Acetate + CoA+ ATP acetyl-CoA + AMP + PPi (a) The ΔG’0 for the … Web8 aug. 1990 · 1. Acetyl-CoA hydrolysis, acetyl-CoA synthesis from acetate and several related fluxes were measured in rat hepatocytes. 2. In contrast with acetyl-CoA … synchronous bowel cancer
