PUFAs are long-chain fatty acids containing two or more double bonds.
They provide structural & functional characteristics, and are involved in a wide range of biological components including membranes (in phospholipids). Equally important PUFAs serve as precursors for conversion into metabolites that regulate critical biological functions.Biodiesel is a non-petroleum and environmentally-friendly alternative to petroleum-based diesel fuel and not fatty acid.PUFA is fatty acid it is not used as it forms epoxide in presence of oxygen.
