HUMAN NUTRITION

Detailed explanation-1: -The tail usually contains even number of carbon atoms. Each fatty acid differs in their chain length, degree of saturation, and position of double bond.

Detailed explanation-2: -The chain length and degree of saturation give way to the properties that are found within the fatty acids and lipids. Unsaturated fatty acids have lower melting points than saturated fatty acids of the same length. Because double bonds cause the hydrocarbon chain to bend.

Detailed explanation-3: -The answer is: Mostly how saturated the chemical bonds in the fat molecule are in hydrogen atoms. The more hydrogen atoms a fatty acid has, the more “saturated” it is, and the higher its melting temperature will be.

Detailed explanation-4: -The degree of saturation of fatty acids describes the number of carbon to carbon double bonds within their structure. The greater the degree of saturation of a fatty acid, the greater its rigidity. Saturated fatty acids have no double bonds.
