Decanoic acid, also known as capric acid, is a saturated fatty acid with a ten-carbon chain. It is commonly found in the milk of various mammals, including coconut oil and palm kernel oil. This fatty acid is often used in the production of soaps, cosmetics, and food additives due to its antimicrobial properties. In addition to its industrial uses, decanoic acid has gained attention in the health and nutrition fields. It is sometimes included in ketogenic diets for its potential benefits in providing energy and supporting brain function. Its unique structure allows it to be metabolized differently than other fats.
