WebMar 5, 2024 · General. Fatty acid synthesis refers to the synthesis of fatty acids from acetyl-CoA or malonyl-CoA. Synthesis itself takes place in the cytosol, but this synthesis (in animal cells) can produce saturated fatty acids which are at most 16 carbons long. The 16 carbon long saturated fatty acid is called palmitic acid, or palmitate. Palmitic acid (hexadecanoic acid in IUPAC nomenclature) is a fatty acid with a 16-carbon chain. It is the most common saturated fatty acid found in animals, plants and microorganisms. Its chemical formula is CH3(CH2)14COOH, and its C:D (the total number of carbon atoms to the number of carbon–carbon double bonds) is 16:0. It is a major component of the oil from the fruit of oil palms (pal…
