Gangliosides of bovine buttermilk. Isolation and characterization of a novel monosialoganglioside with a new branching structure.

Isolation and characterization of a bovine herpesvirus 3 From cases of calf pneumonia in Iran

C20-sphingosine as a determining factor in aggregation of gangliosides.

Aggregation properties of gangliosides, the major synaptic membrane glycosphingolipids of mammalian brain, may prevent their segregation during membrane assembly and promote a uniform membrane matrix with minimum maintenance energy. The sphingosine residues of bovine brain gangliosides show an increase in C20-sphingosine corresponding with an increase in sialic acid. Concentrations of C20-sphin...

Quantitative analysis of gangliosides in bovine milk and colostrum-based dairy products by ultrahigh performance liquid chromatography-tandem mass spectrometry.

Milk gangliosides have gained considerable attention because they participate in diverse biological processes, including neural development, pathogen binding, and activation of the immune system. Herein, we present a quantitative measurement of the gangliosides present in bovine milk and other dairy products and byproducts. Ultrahigh performance liquid chromatography separation was used for hig...

Synthesis, Characterization, and Crystal Structure of a New Coordination Polymer, {[Ba2(Hpydc)2(pydc)(H20)31.H20.(112P3110}n

The reaction of barium chloride with 2, 6-pyridinedicarboxylic acid in water led to the formation of a novelpolymeric complex formulated as {[Ba2(Hpydc)2(pydc)(H20)3].H20.(H2pydc)}.(I). The crystal structure of (I)was characterized by single crystal X-ray diffraction method. The complex was crystallized in the monoclinicsystem with space group P2/c, with four molecule in unit-cell, e.g Z=4. The...

Preparation of GM1 ganglioside with sialidase-producing marine bacteria as a microbial biocatalyst.

This paper describes the preparation of monosialoganglioside GM1 with sialidase-producing marine bacteria as a microbial biocatalyst. A new sialidase-producing bacterium, identified tentatively as Pseudomonas sp. strain YF-2, was isolated from seawater by enrichment culture with ganglioside as the sole source of carbon. When YF-2 was cultured in a synthetic medium containing crude bovine brain ...
