There are about forty naturally occurring fatty acids. The fatty acids without carbon-carbon double bonds are classified as saturated, and those containing carbon-carbon double bonds are classified as unsaturated. Palmitic and stearic acids are the most common saturated fatty acids, and oleic and linoleic acids are the most common unsaturated fatty acids. Oleic acid is monounsaturated because it has only one carbon-carbon double bond. Linoleic, linolenic, and arachidonic acids are polyunsaturated because they have two, three, and four carbon-carbon double bonds, respectively. A way to measure the relative degree of unsaturation of a fat or an oil is to determine its iodine number. The iodine number is the mass of iodine, in grams, that is consumed by (reacts with) 100 grams of a fat or an oil. Iodine reacts with the carbon-carbon double bonds.
