Determination of pH Effects on Phosphatidyl-Hydroxytyrosol and Phosphatidyl-Tyrosol Bilayer Behavior

determination of phosphatidyl choline, phosphatidyl ethanolamine, phosphatidyl inositol and phosphatidic acid in different varieties of soybean cultivated in iran

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...

Complete 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; ...

Studies of Hydrogen Bonding Effects on DiPalmitoyl Phosphatidyl Etanolamine (DPPE) by theoretical Methods

Hydrogen bonding of DPPE with water that surrounded of membrane, plays an important role in permeability ofmembrane that we were presented this matter with analysis of bond angles and torsion angles before and after ofadded water molecules.Interaction with water molecules causes some changes in the geometry of DPPE which were explained bythe contribution of zwitterionic form of DPPE molecule, a...

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.
