the addition of hydrogen atoms to double bonds, or points of unsaturation, in a hydrocarbon. This industrial process is usually done by passing hydrogen gas through liquid vegetable oils.

subclass of essential polyunsaturated fatty acids (PFA) whose first double bond begins at the sixth carbon from the end (omega 6) in the hydrocarbon chain

• omega 3 fatty acid

• omega 6 fatty acid
