Explanation:
Detailed explanation-1: -Unsaturated Fatty Acids Unsaturated fatty acid carbon chains contain one or more double bonds with a terminal carboxylic group (–COOH), unlike saturated fatty acids, which contain no double bonds.
Detailed explanation-2: -Alkenes are hydrocarbons which contain carbon-carbon double bonds. Their general formula is CnH2n for molecules with one double bond (and no rings). Alkenes are also known as olefins, after the original name for ethene, olefiant gas.
Detailed explanation-3: -Those with more than one double bond are called polyunsaturated. The fatty acids in eukaryotic cells are nearly evenly divided between saturated and unsaturated types, and many of the latter may be polyunsaturated.
