Naphthenic acid by a general formula CH O, where "n" indicates the carbon number and "z" specifies a homologous series. The "z" is equal to 0 for saturated, acyclic acids and increases to 2 in monocyclic naphthenic acids, to 4 in bicyclic naphthenic acids, to 6 in tricyclic acids, and to 8 in tetracyclic acids. Salts of naphthenic acids, called naphthenates, are widely used as hydrophobic sources of metal ions in diverse applications.Aluminium salts of naphthenic acid and palmitic acid were combined during World War II to produce napalm. The word "napalm" is derived from the words naphthenic acid and palmitic acid.
SN2 Palmitate a glycerol backbone. The human mammary gland provides the baby with a unique fat composition where the fatty acids arranged in specific combinations, different from the triglycerides in other human tissues and plasma, or from common dietary fats and oils. Palmitic acid (C16:0) is the major saturated fatty acid in human milk, accounting for 17-25% of the total fatty acids, with over 70% of 16:0 is esterified at the milk triglyceride sn-2 position. The major unsaturated fatty acid in human milk is oleic acid (18:1n-9) and this is mostly esterified at the triglyceride sn-1,3 (outer) positions. The positioning of palmitic
