![]() ![]() Short- and medium-chain saturated fatty acids (SFAs) (4 to 12 carbons in length) are found in milk fat, palm oil, and coconut oil. The number of carbons in the chain varies, and the compound may be saturated (containing no double bonds) or unsaturated (containing one or more double bonds). They also contribute satiety, flavor, and palatability to the diet.įatty acids generally consist of a straight alkyl chain, terminating with a carboxyl group. ![]() They are important in the diet as energy sources and as sources of essential fatty acids and fat-soluble vitamins, which tend to associate with fats.
