Answer #1

Among the following fatty acids, The essential fatty acids i.e. the ones which are not synthesised in the body and hence needs to be ingested are :

  • linoleic acid
  • alpha- linoleic acid
  • eicosapentaenoic acid
  • docosahexaenoic acid


  • eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are omega 3 fatty acids along with alpha-linoleic acid (ALA). ALA can be converted to EPA and then to DHA in the body in small amounts. Hence , these are also known as “conditionally essential” fatty acids by some publications.
  • All the others mentioned in the list are non essential fatty acids as the body is able to synthesise these.

(kindly give a positive feedback if satisfied, else please ask for any information needed in the comment section for me to furnish)
