Heptanedioicacid & Pimelicacid, also known as peach acid, is a 7-carbon linear saturated diacid. In animals, it is produced by omega oxidation and β oxidation of fatty acids, and is a by-product of the preparation of ricinic acid (hydroxylated animal oleic acid) from castor oil by GaChemicalbooknttner Fetal in 1884. Müller was isolated from bovine urine in 1937 and has been identified as essential for the growth of certain strains of Diphtheria
