BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Unsaturated fats or oils are usually of plant origin and contain unsaturated fatty acids. The double bond causes a bend or a “kink” that prevents the fatty acids from packing tightly, keeping them liquid at room temperature. Olive oil, corn oil, canola oil, and cod liver oil are examples of unsaturated fats.

Detailed explanation-2: -When the hydrocarbon chain contains a double bond, the fatty acid is said to be unsaturated. Oleic acid is an example of an unsaturated fatty acid. Most unsaturated fats are liquid at room temperature and are called oils.

Detailed explanation-3: -Fatty acid chains with double bonds are unsaturated (Figure 2.7. 13). Those with more than one double bond are called polyunsaturated.

Detailed explanation-4: -In natural unsaturated fatty acids, the cis bonds cause kinks and make them bend instead of sitting in a straight line (Figure 10.5).
