Separations of soy bean inositide fractions of low partition coefficient.
The inositol-containing phosphatides of soy beans have been the subject of a number of investigations (l-7) since 1939 when Klenk and Sakai (8) first reported the presence of inositol in soy bean phosphatides. Previous work at the Northern Regional Research Laboratory (3) has shown that the alcohol-insoluble portion of soy bean phosphatides can be separated into two inositol-containing fraction...
متن کاملComplete fractionation of brain cephalin; isolation from it of phosphatidyl serine, phosphatidyl ethanolamine, and diphosphoinositide.
Brain cephalin (1) has been the name given to a fraction of brain phosphatides characterized by its solubility in ether and insolubility in ethyl alcohol. For many years it was assumed to be a single compound with the chemical structure of diacylglycerylphosphoryl ethanolamine. Work from this laboratory has shown brain cephalin to be a mixture (2). From it were separated two pure phosphatides; ...
متن کاملPreparation of phosphatidyl inositol from baker's yeast.
Phosphatidyl inositol and a cardiolipin-like phospholipid survive the autolysis which is induced in yeast by treating it with toluene, whereas other phospholipids are extensively degraded. Lipid from autolyzed yeast was suspended in isopropanol to extract lecithin and neutral lipid. The insoluble phosphatidyl inositol and cardiolipin were then separated by chromatography on silicic acid.
متن کاملThe development of soy sauce from organic soy bean
Soy sauce with a high salt liquid-state fermentation process was prepared by using organic soy beans as raw material. Beidahuang organic soy bean was selected among different raw materials. Here, the best technique was determined. Firstly, the organic soy beans were soaked for 7 hours under 121°C , steamed for 15 min and mixed with the fried wheat (5:5, w/w). After inoculated with Aspergillus o...
متن کاملSynthesis of an unsaturated diether analogue of phosphatidyl ethanolamine.
A synthesis of racemic diether analogues of glyceryl phosphatides is reported which is applicable to unsaturated aliphatic substituents. The "oleyl" diether analogue of phosphatidyl ethanolamine has been synthesized.
