introduction: crude vegetable oils contain some quantities of phospholipids. the highest concentration of phospholipids is usually found in crude soybean oil. the presence of phospholipids in the crude and refined oils create undesirable effects on the quality and quantity of the oil during refining operations or use by the consumer. however, if phospholipids are extracted properly from the oil...
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 ...
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...
Female patients in reproductive age with systemic lupus erythematosus and fertility complications together are observed by rheumatologists, gynecologists, and reproductive immunologists. The paper notes the presence of autoantibodies to zona pellucida, to phospholipids (phosphatidyl serine, phosphatidyl ethanolamine, phosphatidyl inositol, phosphatidyl glycerol, phosphatidic acid, annexin V, be...
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...
Prostate cancer commonly metastasizes to bone due its favorable microenvironment for cell growth and survival. Currently, the standard of care metastatic prostate is medical castration in conjunction with chemotherapeutic agents newer anti-androgen/androgen receptor therapies. While these therapies aim improve quality life patients advanced disease, resistance inevitable prompting development c...
Glycolipids extracted with pyridine from three strains of Mycobacterium tuberculosis were fractionated. Phosphatidyl inositol, two phosphatidyl inositol dimannosides (A and M), and two phosphatidyl inositol pentamannosides (G and K) were separated and purified by a combination of solvent fractionations and chromatography on silicic acid. In each of these lipids, palmitic and tuberculostearic ac...
Nutritional deprivation of proteins decreases the protein kinase C (PKC) activity in rat lung. The activity of (PKC) is influenced by lipid metabolism. Changes in PKC activity may influence phosphorylation of its substrate proteins in the tissues. Therefore, alterations in phospholipid metabolism and PKC mediated protein phosphorylation in dietary protein deficiency in rat lung were envisaged. ...
The steps between exposure of bovine adrenal glomerulosa cells to angiotensin and the stimulated increase in aldosterone production were studied in two ways. Binding of angiotensin to receptors, and hormone effects on phosphatidyl inositol turnover, 45Ca2+ fluxes, and aldosterone production were measured directly. Other potential intermediate steps were investigated indirectly by use of inhibit...
The steps between exposure of bovine adrenal gloraerulosa cells to angiotensin and the stimulated increase in aldosterone production were studied in two ways. Binding of angiotensin to receptors, and hormone effects on phosphatidyl inositol turnover, u C i ' + fluxes, and aldosterone production were measured directly. Other potential intermediate steps were investigated indirectly by use of inh...
