The four types have different chemical structures and physical properties. The bad fats, saturated and trans fats, tend to be more solid at room temperature (like a stick of butter), while monounsaturated and polyunsaturated fats tend to be more liquid (like liquid vegetable oil). Fats can also have different effects on the cholesterol levels in your body.
Unsaturated fats are those that have one or more double bonds in their fatty acid chains. Made up of two kinds of fats, monounsaturated and polyunsaturated, these fats provide slightly fewer calories than saturated fats and somewhat less energy. Unsaturated fats are in liquid form at room temperature. Polyunsaturated fats also contain Omega-3 fatty acids, an essential fatty acid that your body cannot make on its own, but one that is necessary to maintain a healthy body.
