A fatty acid is a long chain of carbons, typically with a carboxylic acid group on one end. These carbons are usually bonded to hydrogen atoms and can have double bonds between some of the carbons (making the fatty acid unsaturated). Fatty acids are not made up of glucose molecules or ring-like structures.
