[Gas-liquid chromatography of non-esterified fatty acids of the rat myocardium].
Non-esterified fatty acids in cardiac cell cultures of postnatal rat, in postnatal rat heart and in ventricle muscle of adult rat were analyzed by gas-liquid chromatography. Among cultured heart cells, three different types were found. Type A0 appeared when arachidonic acid was lacking in tissue culture medium; it had the highest percentage in saturated fatty acids, palmitoleic and linolenic acids. Type A1 and type A2 appeared when arachidonic acid was proved to be present in culture medium. Non esterified fatty acid composition of type A1 was closely similar to that of postnatal rat heart, while type A2 ranged between that of postnatal heart and that of adult ventricular muscle.
