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.
