And the way that we basically go from this name to the name of this particular fatty acid is by removing the E at the end of the hydrocarbon name and replacing it with OIC and then adding acid afterwards. So in this particular case, we have hexadechanoic. Acid is the proper systematic name for the more common name of palmitic acid. So, generally speaking, the name of a fatty acid is derived from the hydrocarbon component. So we begin with the hydrocarbon name, remove the E at the end of the name and simply replace it with OIC and then add acid. The acid is there because we also have that carboxylic acid at the end of that hydrocarbon name.
