Chemical Information
FooDB NameHexadecanoic acid
DescriptionOccurs in the form of esters (glycerides) in oils and fats of vegetable and animal origin. Usually obtained from palm oil. Widely distributed in plants. Defoaming agent, lubricant and fruit coating constituent Palmitic acid is the first fatty acid produced during lipogenesis and from which longer fatty acids can be produced.; Palmitic acid, or hexadecanoic acid is one of the most common saturated fatty acids found in animals and plants.
