Because most of them are liquid at room temperature, we call them oils. Corn oil, canola rhymes:english: æt oil, cottonseed oil, peanut oil, and olive oil are common examples. As this list suggests, plant fats tend to be unsaturated (therefore rhymes:english: æt "oils"). Fats from such animals as cattle tend to be saturated. Trans fatty acids Because the most abundant (and least expensive) source of fat is rhymes:english: æt from plant oils but many cooking applications, particularly baked products, need solid fats the food industry uses hydrogenated oils for things like shortening and margarine. In hydrogenation, plant oils are exposed to hydrogen at a high temperature and in the presence of a catalyst. |

| They may contain as few as 4 carbon atoms or as many as 24. Because fatty acids are synthesized from fragments containing two carbon atoms, the number of carbon atoms in the chain is almost always an even number. In animal fats, 16-carbon (palmitic acid) and 18-carbon (stearic acid - shown here) fatty acids are the reference most common. Unsaturated Fats Some fatty acids have one or more double bonds between their carbon atoms. They are called unsaturated because they reference could hold more hydrogen atoms than they do. Monounsaturated fats have a single double bond in their fatty acids. Polyunsaturated reference fats, such as trilinolein shown here, have two or more. Double bonds are rigid and those in natural fats introduce a kink in the molecule. |
