The mode of free fatty acid (FFA) liberation from the mouse brain during ischemia was investigated at various times after decapitation and under nizofenone treatment. Normal nonischemic brain FFAs consist mainly of palmitic acid (16:0), stearic acid (18:0), and oleic acid (18:1) with smaller amounts of arachidonic acid (20:4), docosahexaenoic acid (22:6),(More)
A convenient and reliable gas-liquid chromatographic method for determining the free fatty acids in biological specimens is described. The free fatty acids were extracted with hexane in the presence of H3PO4 and then back-extracted from the hexane phase into a very small volume of trimethyl (alpha, alpha, alpha-trifluoro-m-tolyl)ammonium hydroxide solution.(More)
