摘要: Abstract Cardiolipins of rat tissues were isolated by column chromatography and analyzed. The P content ranged from 2.61% to 3.64%. ester:P ratio varied 1.63 2.09, the glycerol:P ratios 1.34 1.68. fatty acid spectrum tissue cardiolipins showed some, like heart, kidney liver be highly unsaturated others brain, lung testis saturated. Analysis acids released phospholipase A demonstrated that certain are preferentially β-linked, but on whole, distribution is much more random than other phospholipids, lecithins. All degraded hot acetic yield diglycerides, very small amounts monoglycerides, P-containing products. However, only with rat-liver cardiolipin, beef-heart a synthetic cardiolipin appreciable water-soluble released. On treatment sodium methoxide at 0° all give rise 4–6 lyso-derivatives resulting sequential loss one or acids. eventually completely methyl esters, compound smaller products including free vitamin A. In case alkaline hydrolysis yields not in stoichiometric amount. react [14C]acetic anhydride radioactive acetylated derivative. results this investigation show whereas has structure consistent recently synthesized structure.
