Elongation Elongation can occur in most tissues; the process differs in the endoplasmic reticulum vs. the mitochondria. Elongation: Fatty Acid Synthesis in the Endoplasmic Reticulum In endoplasmic reticulum the reactions resemble those of de novo fatty acid synthesis. The overall reaction: This shows the overall process of fatty acyl elongation in the endoplasmic reticulum. The process resembles that catalyzed by fatty acyl synthase, but the individual activities

Unformatted text preview: appear to be on separate enzymes. Notice that malonyl CoA is the source of the added carbons, as in de novo fatty acid synthesis. The activities are closely associated with the endoplasmic reticulum membranes. The activities are separable; they are not part of a multifunctional enzyme. No ACP is involved; CoA esters are used directly....
