The omega-3 title additionally has to do with the construction and double bond placement. Every finish of the fatty acid chain has a Greek title of both “alpha” (the beginning) or “omega” (the top).
A fatty acid is taken into account an omega-3 if the primary double bond happens three carbon atoms away from the “omega” finish of the chain.
