General Comment
2011-04-14 The smallest H(CH2)nCOOH acid that exhibits the properties of the other fatty acids. Found in dairy foods and, as an end-product of carbohydrate digestion, in the mammalian gastrointestinal tract. Used as an antifungal agent in food, it is also a major contributor to organic acidurias.
