WebGenetic analysis showed that blocking fatty acid peroxisomal β-oxidation, the sole pathway for metabolic breakdown of fatty acids in plants, significantly compromised or stunted the growth and development of mutants defective in starch synthesis under long days or short days, respectively. WebFatty acids are normally synthesized from acetyl-CoA, a process that requires ATP, biotin, Mg++, and Mn++. Acetyl-CoA carboxylase, the rate-limiting enzyme in fatty acid biosynthesis, is inhibited by glucagon and epinephrine, and stimulated by insulin. Intermediates in fatty acid biosynthesis are attached to acyl carrier protein (ACP).
