List of fatty acids: IUPAC and common names, shorthands

List of fatty acids present in foods

Below is a list of the main fatty acids found in foods. These are saturated, monounsaturated and polyunsaturated fatty acids, of which the common name, the IUPAC name and the shorthand notation are specified.
In the shorthand notation the first number indicates how many carbon atoms are present in the molecule whereas the second the number of double bonds in the carbon chain. This type of notation cannot be used for trans fatty acids.
