WebFatty acids are synthesized from acetyl-CoA through seven chain elongation steps, increasing by two carbons each time, to produce a 16-carbon fatty acid called palmitic acid; most synthesized fatty acids are esterified into triglycerides for storage. Fatty acids can be synthesized from the break down of carbohydrates into acetyl-CoA molecules. WebFatty acid biosynthesis (and most biosynthetic reactions) requires NADPH to supply the reducing equivalents. Oxaloacetate is used to generate NADPH for biosynthesis in a …
