Reference Entry
Fatty Acids, a large group of organic compounds that are weakly acidic. They are called �fatty� because the first of them to be isolated came from natural fats and oils (liquid fats). These acids are compounds of carbon, hydrogen, and oxygen. The lower members of the group (those having a small number of carbon atoms in each molecule, such as acetic acid and butyric acid) are volatile liquids. The higher members are solids. Combined with glycerol, forming compounds called glycerides, the higher fatty acids are found in natural fats and oils. All fatty acids are soluble in alcohol, benzene, chloroform, and ether.
