HUMAN NUTRITION

Detailed explanation-1: -Carbon-carbon double bonds (unsaturations) are found in naturally occurring fatty acids. There may be one double bond or many, up to six in important fatty acids. Fatty acids with one double bond are the most prevalent in the human body, comprising about half of the total.

Detailed explanation-2: -Fatty acids containing one or more carbon–carbon double bonds are termed ‘unsaturated. ‘ When the fatty acids contain one carbon–carbon double bond in the aliphatic chain, they are called monounsaturated.

Detailed explanation-3: -Introduction. Omega-6 and omega-3 fatty acids are polyunsaturated fatty acids (PUFA), meaning they contain more than one cis double bond (1). In all omega-6 (6 or n-6) fatty acids, the first double bond is located between the sixth and seventh carbon atom from the methyl end of the fatty acid.
