WebJun 9, 2024 · Lipids consist of repeating units called fatty acids. Fatty acids are organic compounds that have the general formula CH 3(CH 2) nCOOH, where n usually ranges from 2 to 28 and is always an even number. There are two types of fatty acids: saturated fatty acids and unsaturated fatty acids. Saturated Fatty Acids Long-chain fatty acids (LCFA) with 13 to 21 carbons (e.g. petroselinic acid). Very long chain fatty acids (VLCFA) with 22 or more carbons (e. g. cerotic acid with 26) A triglyceride molecule may have fatty acid elements of different lengths, and a fat product will often be a mix of various triglycerides. See more A triglyceride (TG, triacylglycerol, TAG, or triacylglyceride) is an ester derived from glycerol and three fatty acids (from tri- and glyceride).
