saturated fat

Saturated fat is fat that consists of triglycerides containing only saturated fatty acids. Saturated fatty acids have no double bonds between the carbon atoms of the fatty acid chain; hence, they are fully saturated with hydrogen atoms. There are several kinds of naturally occurring saturated fatty acids, their only difference being the number of carbon atoms - from 1 to 24. Some common examples of saturated fatty acids are butyric acid with 4 carbon atoms (contained in butter), lauric acid with 12 carbon atoms (contained in breast milk, coconut oil, palm oil), myristic acid with 14 carbon atoms (contained in cow milk and dairy products), palmitic acid with 16 carbon atoms (contained in palm oil, hence the name, and meat), and stearic acid with 18 carbon atoms (also contained in meat and cocoa butter).

Saturated fat n. A fat, most often of animal origin, having chains of saturated fatty acids. An excess of these fats in the diet is thought to raise [more]Saturated fat - Community and Resources

Any dietary fat in which hydrogen-saturated fatty acids predominate. Meat, eggs, and tropical oils (such as coconut, palm, and palm kernel oils) contain saturated fats in large proportions.

Compare with unsaturated fat .A lipid that contains no carbon-carbon double bonds. Animal fats like butter and lard are composed of saturated fat. Saturated fats tend to be waxy or greasy solids.
