Fatty acids to acetyl-coa
Fats are broken down by conversion to acyl-CoA. This conversion is one response to high energy demands such as exercise. The oxidative degradation of fatty acids is a two-step process, catalyzed by acyl-CoA synthetase. Fatty acids are converted to their acyl phosphate, the precursor to acyl-CoA. The latter conversion is mediated by acyl-CoA synthase" WebAcetyl-CoA normally arises in the cell as a product of the glycolytic cycle or by β-oxidation of fatty acids in the mitochondria. In addition, acetyl-CoA can also be formed by direct …

WebAcetyl CoA that is produced from the oxidation of fatty acids and enters the citric acid cycle is used in the de novo synthesis of pyruvate. Acetoacetate is a normal, major energy source for the brain, heart muscle, and renal cortex. This problem has been solved! WebStep 1. In the first step of the citric acid cycle, acetyl \text {CoA} CoA joins with a four-carbon molecule, oxaloacetate, releasing the \text {CoA} CoA group and forming a six-carbon molecule called citrate. Step 2. In the …
WebThe rate-limiting step in fatty acid synthesis is: A) condensation of acetyl-CoA and malonyl-CoA. B) formation of acetyl-CoA from acetate. C) formation of malonyl-CoA from malonate and coenzyme A. D) the reaction catalyzed by acetyl-CoA carboxylase. E) the reduction of the acetoacetyl group to a β-hydroxybutyryl group. WebAcetyl-CoA formation occurs inside or outside the cell mitochondria. As a metabolite (a substance necessary for metabolism), acetyl-CoA must be freely available. It can be …

The process of post-translational modification ...
WebAcetyl-SCoA provides the carbon used for fatty acid synthesis. The reactions of lipogenesis include, but are not limited to, two reductions and a dehydration. Malonyl CoA adds a two-carbon group to the growing fatty acid chain with each cycle. The growing fatty acid chain is bound to an acyl carrier protein (ACP).
