Influence of Ca2+ and Temperature Changes on the Surface Requirement of Gangliosides and Phospholipial mixtures of peptides and gangliosides and of natural ganglioside mixtures from bovine and ice- fish brain were investigated by means of a Wilhelmy balance in a rectangular teflon trough. The surface pressure/area isotherms were compared at 11°, 20° and 37° C and different Ca.-concentrations in th

Fundamentals of Brain Ganglioside Biosynthesise asymmetrically located in the outer membrane leaflet with their oligosaccharide moiety protruding on the membrane surface (1). Very small amounts of gangliosides are also present in intracellular structures. These gangliosides likely represent the transient forms moving from the site of biosynthes

At the end of their work, they made the following statement: “The composition of our preparation suggests the possibility that they contain certain specific groups similar to those of the bacterial haptenes studied by Avery and Heidelberger.” Thus they assumed the active

With this ‘soft ionization’ technique that allows ionization of polar compounds from a solution in a high boiling liquid in combination with high field magnets and highly sensitiv

(7) reported the further improvement of this method by including an additional step using a Sephadex LH-20 column eluted with 0.05N HCl.

Fundamentals of Structural Analysis of Glycosphingolipids by Proton Nuclear Magnetic Resonance Specty, on the other hand, is well-suited for providing the primary and secondary structure of glycosphingolipids because this method is rapid, quantitative, sensitive and nondestructive. However, previous utilization of proton NMR has yielded only incomplete data concerning the primary structure of thes
