This prevents the fatty acids from packing close together and as a result, unsaturated fats have a lower melting point than do saturated fats But sometimes, the carbons bond to each other with double bonds, leaving room for only one hydrogen. The American Heart Association recommends limiting saturated fats – which are found in butter, cheese, red meat and other animal-based foods. Saturated fats have no double bond between molecules, which means there are no gaps and the fat is saturated with hydrogen molecules. Unsaturated fats contain one or more double or triple bonds between the molecules. Cholesterol has a more complex chemical structure when compared to fats. The double bonds in unsaturated fats can be converted into single bonds by reaction with hydrogen effected by a catalyst. If there is just one double bond, it is a monounsaturated fat. Fat or lipid is an important macromolecule which contains a central glycerol molecule and three ��� Saturated fatty acids do not have double bonds, contain only single bonds, whereas unsaturated fatty acids have one or more double bonds.
