HUMAN NUTRITION

Detailed explanation-1: -Answer and Explanation: An unsaturated fatty acid has no double bonds in its fatty acid tail.

Detailed explanation-2: -Unsaturated fatty acids have at least one double bond between the carbon atoms in the hydrocarbon chain. Each double bond between carbon atoms takes the place of two hydrogen atoms, resulting in fewer hydrogen atoms in the hydrocarbon chain overall and causing the structure to kink.

Detailed explanation-3: -Unsaturated fats have one or more double bonds between between carbons in the fatty acid chain. Explanation: Unsaturated fats have at least one double bond between two carbons in the fatty acid and do not have the maximum number of hydrogens. They do not contain nitrogen and are usually liquid at room temperature.

Detailed explanation-4: -Unsaturated fats are missing hydrogen atoms and therefore have double bonds between carbon atoms in the fatty acid chain. This means that the chain of hydrogen atoms is broken up, causing the fats to liquefy at room temperature. Unsaturated fats are found in plants, nuts, seeds, and some types of fish.
