Preparation 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 کاملBinding of antibodies onto the thylakoid membrane. IV. Phosphatides and xanthophylls in the outer surface of the thylakoid membrane.
Antisera to the phosphatides phosphatidyl inositol and phosphatidyl choline as well as to the xanthophylls violaxanthin and zeaxanthin were obtained by immunization of rabbits. The phosphatidyl choline antiserum did not give cross reactions with thylakoid membrane glycolipids, nor with phosphatidyl glycerol and phosphatidyl inositol. The antiserum to phosphatidyl inositol also did not react wit...
متن کاملBrain diphosphoninositide, a new phosphatide having inositol metadiphosphate as a constituent.
Work from this laboratory has established that brain cephalin (1, 2) is a mixture of three different phosphatides; namely, phosphatidyl serine (3), phosphatidyl ethanolamine, and diphosphoinositide. In a preliminary note (4) it has been shown that diphosphoinositide has inositol metadiphosphate’ as a constituent. The present paper contains detailed proof of this statement and reports some other...
متن کاملEffect of phospholipids on estrogen receptor of rat uterine cytosol.
Phospholipids such as phosphatidyl inositol and phosphatidyl serine inhibit the binding of R5020 and progestin receptors. The effect of phospholipids on the binding of estrogen and estrogen receptors of rat uterine cytosol was studied. Phosphatidyl choline, sphingomyelin, phosphatidyl inositol, phosphatidyl ethanolamine, cardiolipin, and phosphatidic acid inhibited the binding of estradiol and ...
متن کاملRemoval of the sphingolipid impurity from preparations of yeast phosphatidyl inositol.
A complex sphingolipid containing inositol and mannose, present in lipid extracted from toluene-autolyzed baker's yeast, was eluted from silicic acid columns immediately after phosphatidyl inositol, and was the main nitrogenous impurity in crude preparations of this phospholipid. Nitrogenfree phosphatidyl inositol was obtained by rechromatography on alumina. Modifications to the chromatographic...
