Bis-sulfated gangliotetraosylceramide from rat kidney.
A novel bis-sulfated tetraglycosylceramide containing N-acetylgalactosamine was isolated from the lipid extract of rat kidney. The isolation procedure involved extraction of lipids with chloroform/methanol, alkaline methanolysis, and column chromatographies with DEAE-Sephacel and silica beads. By infrared spectroscopy, proton magnetic resonance spectroscopy, periodate oxidation, solvolysis, chr...
متن کاملUDP-N-Acetylgalactosamine: globoside a-3-N-Acetylgalactos- aminyltransferase
A UDP-N-acetylgalactosamine:globoside a-3-N-acetylgalactosaminyltransferase has been purified over 3500-fold in 4% yield from a Triton X-100 extract of canine spleen microsomes by affinity chromatography on globoside acid-agarose. Sodium dodecyl sulfate gel electrophoresis of the purified enzyme revealed two major bands with molecular weights of 66,000 and 56,000. Judging from the molecular wei...
متن کامل[N,N′-Bis(3-methoxy-2-oxidobenzylidene)ethylenediammonium-κ4 O,O′,O′′,O′′′]tris(nitrato-κ2 O,O′)dysprosium(III)
In the title mononuclear Schiff base complex, [Dy(NO(3))(3)(C(18)H(20)N(2)O(4))], the Dy(III) ion is ten-coordinated in a distorted hexa-deca-hedral geometry by six O atoms of three nitrate anions and four O atoms of the Schiff base ligand. An intra-molecular N-H⋯O hydrogen bond occurs. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds.
متن کاملBis(N-nitroso-N-pentylhydroxylaminato-κ2 O,O′)copper(II)
In the centrosymmetric title compound, [Cu(C5H11N2O2)2], the Cu(2+) ion, located on an inversion centre (Wyckoff position 2b), is in a square-planar environment, surounded by four O atoms of the N-O groups of two N-nitroso-N-pentyl-hydroxy-laminate ligands [Cu-O = 1.9042 (17) and 1.9095 (16) Å]. The hy-droxy-laminate monoanions are bidentate chelating ligands. The Cu(2+) cations form stacks alo...
متن کاملBis(N-benzoyl-N-phenylhydroxylaminato-κ2 O,O′)dimethyltin(IV)
The Sn atom in the title compound, [Sn(CH(3))(2)(C(13)H(10)NO(2))(2)], has a highly distorted octa-hedral coordination with the equatorial plane made up of four O atoms from two N-benzoyl-N-phenyl-hydroxy-laminate ligands and the axial positions occupied by two methyl groups. The crystal structure is stabilized by van der Waals inter-actions.
