N-[4-(β-d-Allopyranosyloxy)benzylidene]methylamine
The title compound, C(14)H(19)NO(6), was synthesized by the condensation reaction between hecilid (4-formyl-phenl-β-d-allopyran-oside) and methyl-amine in methanol. In the crystal structure, the pyran ring adopts a chair conformation and adjacent mol-ecules are linked by inter-molecular O-H⋯O and O-H⋯N hydrogen bonds, forming a three-dimensional network.
متن کاملRole of N-acetyl-β-d-hexosaminidase in cholesteatoma tissue
Cholesteatoma is a destructive disease characterized by the progressive expansion of keratinizing squamous epithelium in the middle ear and mastoid, and chronic inflammatory reaction of the subepithelial connective tissue. N-Acetyl-β-d-hexosaminidase (HEX) catalyzes the release of terminal non-reducing N-acetyl-d-hexosamine residues acting on glucosides and galactosides in glycoproteins, GM2-ga...
متن کاملn-Propyl 2,3,4,6-tetra-O-acetyl-β-d-glucopyranoside
THE TITLE COMPOUND [SYSTEMATIC NAME: (2R,3R,4S,5R,6R)-2-(acet-oxy-meth-yl)-6-propoxytetra-hydro-2H-pyran-3,4,5-triyl triacetate], C(17)H(26)O(10), was formed by a Koenigs-Knorr reaction of 2,3,4,6-tetra-O-acetyl-α-d-glucopyranosyl bromide and n-propanol. The central ring adopts a chair conformation. The crystal does not contain any significant inter-actions such as hydrogen bonds.
متن کاملA Sperm–Plasma β-N-Acetyl-D-Hexosaminidase Interacting with a Chitinolytic β-N-Acetyl-D-Hexosaminidase in Insect Molting Fluid
Insects require molting fluids to shed the old cuticle during molting. β-N-acetyl-D-hexosaminidase, known as Hex1, together with various chitinases, is responsible for degrading the chitin component of the old cuticle. This study showed that another β-N-acetyl-D-hexosaminidase, termed OfHex3, interacted with Hex1 and functioned in the molting fluid, although the homolog of OfHex3 was known as a...
متن کاملN,N,N-Trimethyl-N-(methyl 5-deoxy-2,3-O-isopropylidene-β-d-ribofuranosid-5-yl)ammonium 4-methylbenzenesulfonate sesquihydrate
The structure of the title compound, [C12H24NO4][C7H7O3S]·1.5H2O, contains alternating layers parallel to (001) of hydro-phobic and polar character, stabilized by C-H⋯O hydrogen bonding. The furan ring adopts an envelope conformation with the C(OMe) atom as the flap, and the dioxolane ring is twisted about one of the O-C(methine) bonds. A comparison to related compounds is presented. The tosyl-...
