unsaturated fatty acid
Unsaturated-fat meaning A fat derived from plant and some animal sources, especially fish, that is liquid at room temperature. Intake of foods containing more unsaturated fats than saturated fats may contribute to reduced blood cholesterol levels. An unsaturated fat is a fat or fatty acid in which there is at least one double bond within the fatty acid chain. A fatty acid chain is monounsaturated if it contains one double bond, and polyunsaturated if it contains more than one double bond. Where double bonds are formed, hydrogen atoms are eliminated.
