WebJul 19, 2024 · For example, the 16-carbon fatty acid palmitic acid (palmitate at pH 7) undergoes seven passes through this oxidative sequence, in each pass losing two carbons as acetyl-CoA. At the end of seven cycles the last two carbons of palmitate (originally C-15 and C-16) are left as acetyl-CoA. How are palmitate and citrate fatty acids synthesized? WebFatty acid synthesis begins with the activation of acetyl CoA, in a two-step reaction, to malonyl CoA. • 3.
