There are two main types of triglycerides, saturated and unsaturated fats. Saturated fats have carbon atoms that have the maximum number of hydrogen atoms possible. Saturated fats have a higher melting point and are usually solid at room temperature. Unsaturated fats have a least one carbon-carbon double bond, so there are not as many hydrogen atoms on the carbons. Unsaturated fats have a lower melting point and are usually liquid at room temperature. Oils are usually unsaturated fats. Saturated fats give the body more energy than unsaturated fats.
