WebMalonyl‐CoA contains a 3‐carbon dicarboxylic acid, malonate, bound to Coenzyme A. Malonate is formed from acetyl‐CoA by the addition of CO 2 using the biotin cofactor of the enzyme acetyl‐CoA carboxylase. WebFatty acid synthesis begins with the activation of acetyl CoA, in a two-step reaction, to malonyl CoA. • 3. The reaction intermediates are attached to an acyl carrier protein, which is the molecular foundation for the fatty acid being constructed. Fatty acid is synthesized, two carbon atoms at a time, in a five-step elongation cycle.
