structural characterization of the fatty acid chain can be achieved as the released saturated carboxylate anions undergo a highly specific 1,4-elimination of h2 , which results in the losses of the elements of ch4 , c2h6 , c3h8 . . . in a fashion entirely consistent with the chemistry of carboxylate anions desorbed from free fatty acids .
