Chibnall and Channon, investigating the cytoplasma of cabbage and spinach leaves (I), isolated a mixture of substances which resembled monophosphatides in their structure and composition, but mere virtually free of nitrogenous bases. The main constituents were identified as the calcium, magnesium, and potassium salts of phosphoric acid esters of diglycerides. These compounds, constituting a new...

The effects of intratracheally instilled silica (10 mg/rat) on the biosynthesis of surfactant phospholipids was investigated in the lungs of rats. The sizes of the intracellular and extracellular pools of surfactant phospholipids were measured 7, 14 and 28 days after silica exposure. The ability of lung slices to incorporate [14C]choline and [3H]palmitate into surfactant phosphatidylcholine (PC...

The lateral lipid organization and the local surface curvature in small and giant bilayer vesicles of binary lipid mixtures were investigated. Mixtures of the following lipids are studied: Cholesterin, di-alcyl-lecithins, dioleyl-lecithin and di-alcyl-phosphatidic acid. The latter is con­ sidered as being representative of charged natural lipids (e .g . phosphatidyl serine or cardiolipin). Thre...
