WebSep 16, 2024 · Fatty Acid Biosynthesis: Chain-Length Regulation and Control De novo biosynthesis of fatty acids is an iterative process requiring strict regulation of the lengths of the produced fatty acids. In this review, we focus on the factors determining chain lengths in fatty acid biosynthesis. WebMar 6, 2024 · Fatty acid synthesis occurs in the cytoplasm of eukaryotic cells. Transport of acetyl-CoA from the mitochondrial matrix occurs when it begins to build up. This happens when the citric acid cycle slows or stops from lack of exercise. Two molecules can play roles in moving acetyl-CoA to the cytoplasm – citrate and acetylcarnitine.
