They can be found in unrefined cereal grains, beeswax, and many plant-derived foods. In chemistry, particularly in biochemistry, a fatty acid is a carboxylic acid with an aliphatic chain, which is either saturated or unsaturated.Most naturally occurring fatty acids have an unbranched chain of an even number of carbon atoms, from 4 to 28.

The net effect as that the ester bonds are broken. Fatty alcohols are aliphatic alcohols derived from natural fats and oils, originating in plants, but also synthesized in animals and algae.Their significance in nutrition and health has historically been overlooked, and is only now being realized, as they are closely related to fatty acids, including the well-documented omega 3 fatty acids.The other counterparts are fatty aldehydes.
