Unsaturated fatty acids are often classified according to the number of carbon atoms between the terminal methyl carbon (the omega carbon) and the closest double bond to the methyl end of the chain. an omega‑3 fatty acid, for example, would have a double bond in position 3 counting from the methyl end of the molecule. identify which omega class each fatty acid belongs to.

Omega-3 and omega-6

Explanation:

Fatty acids are carboxylic acids normally have a long unbranched aliphatic chain. Fatty acids are divided into two parts; (1) saturated(with no double bond) and (2). unsaturated fatty acids(with at least one pair of double bond which of course allow the addition of other atoms).

Unsaturated fatty acids are further divided into two; (a). Monounsaturated(only one double bond) and (b). Polyunsaturated fatty acids (more than one double bond based on the length of the chain).

Based on the length of the chain we have; omega 3 and omega-6 fatty acids. Alpha-linoleic acid is an example of omega-3.
