HUMAN NUTRITION

Detailed explanation-1: -Polyunsaturated fats are fats in which the constituent hydrocarbon chain possesses two or more carbon–carbon double bonds. Polyunsaturated fat can be found mostly in nuts, seeds, fish, seed oils, and oysters.

Detailed explanation-2: -Unsaturated fatty acids can be further divided into monounsaturated (which contains only one double bond) or polyunsaturated fatty acids (PUFAs), which contain more than one double bond. PUFAs are further grouped based either on the location of the double bonds and/or according to the chain length.

Detailed explanation-3: -Polyunsaturated fatty acid (polyunsaturated fat): A fatty acid having two or more carbon-carbon double bonds in its carbon chain. Stearic acid lacks a carbon-carbon double bond in its carbon chain, so this molecule is a saturated fatty acid.
