Vegetable oils have polyunsaturated fatty acids, monounsaturated fatty acids, and saturated fatty acids. However, the percentage of each type of fatty acid differs between different vegetable oils.

Explanation:

Fatty acids consist of a hydrocarbon chain bonded to a carboxylic acid group #("COOH")#. If the hydrocarbon chain contains no double-bonded carbon atoms, it is saturated with hydrogen atoms. If the hydrocarbon chain contains one pair of double-bonded carbon atoms, it is monounsaturated because it has fewer hydrogen atoms. If the hydrocarbon chain contains more than one pair of double-bonded carbon atoms, it is polyunsaturated, and contains even fewer hydrogen atoms.

The unsaturated fatty acid is monounsaturated.

The omega-3 and omega-6 fatty acids are polyunsaturated.
