The chemistry of fatty acids is described in lectures for most introductorv courses of chemistrv and hiochemistrv: vet. in the laboratory classes, fatty acids are rarely handled bn the gram scale ( I ) . Fatty acids are obtained easily and cheaply in the form of their triglycerides which are present in the commercial products, e..g, corn oil, cottonseed oil, and tallow.
