Weboxidation energy of fatty acids is released by removal of 2-C at a time (oxidation) at the -carbon position (C3) 2-C are released in the form of acetyl CoA, which can then enter TCA cycle to generate ATPs 3 steps: activation of fatty acid (cytosol) fatty acid + CoA => fatty acyl CoA transport of fatty acyl CoA into mitochondria ... WebIts main function is to catalyze the synthesis of palmitate (C16:0, a long-chain saturated fatty acid) from acetyl-CoA and malonyl-CoA, in the presence of NADPH. The fatty acids are synthesized by a series of decarboxylative Claisen condensation reactions from acetyl-CoA and malonyl-CoA. greene county pa 911

"WebHigh levels of palmitate are expected to increase acetyl-CoA content and the NADH/NAD + ratio. In mitochondria, the increased acetyl-CoA would promote acetylation while the increased NADH/NAD + ratio would compromise the activity of the primary mitochondrial deacetylase, sirtuin 3 (SIRT3), which uses NAD + as a cofactor 24.
