Question

why maximum no. of double bonds is 4 in essential fatty acids.​

Answer 1

Answer:

Unsaturated fatty acids have one or more double bonds like oleic acid (one), linoleic acid (two), linoleic acid (three), and arachidonic acid (four). An unsaturated fatty acid with one double bond is called mono unsaturated fatty acid (MUFA). Fatty acid with more than one double bond is called as polyunsaturated fatty acid (PUFA). Animals cannot synthesize fatty acids with double bonds (Linoleic, Linoleic and Arachidonic acids). Hence, these fatty acids must be obtained in diet and are thus called essential fatty acids.
