glycosidic bondhydroxylDFTAIMDMechanistic insights into glycosidic bond activation in cellulose pyrolysis were obtained via first-principles density functional theory calculations that explain the peculiar similarity in kinetics for different stereochemical glycosidic bonds (beta vs alpha) and establish the role...
Alpha Helix and Beta Sheet The primary structure of a protein is the amino acid sequence of the polypeptide chain. The way the polypeptide chain forms hydrogen bonds determines the secondary structure. There are two main types of secondary structures in proteins, alpha helices and beta pleated ...
2015). An alpha-CGTase was obtained fromB. licheniformisand showed excellent activity at acidic pH, around 6.0, and at 40 °C (Jamil et al., 2017). AB.cereusstrain showed greater beta-CGTase activity at pH 9.0 and at 50 °C and stability over a wide pH range of 6.0–10.0 and tempera...
These units are linked with α-1,4 glycosidic bonds. These units have hydrophilic outer surfaces and lipophilic inner cavities. The major cyclodextrins are α-cyclodextrin, β-cyclodextrin and γ-cyclodextrin with 6, 7 and 8 glucopyranose units respectively. The aqueous solubility of cyclodextrins is...
ALPHA-D-CELLOBIOSE OCTAACETATE (CAS 3616-19-1, C28H38O19), is a white solid, widely used in the pharmaceutical and food industries, with excellent solubility in organic solvents. It is a derivative of cellobiose, a disaccharide composed of two glucose units linked by a β(1→4) glycosidic...
Ab initio determination of the electronic structure of beryllium-, aluminum-, and magnesium-nitrides: A comparative study We have investigated the electronic properties, in different crystal phases of the BeN(alpha and beta), AlN (wurtzite and zinc blende) and MgN, compounds w... M Moreno Arme...
Characterization of two different endo-α-N-acetylgalactosaminidases from probiotic and pathogenic enterobacteria, Bifidobacterium longum and Clostridium p... Endo-alpha-N-acetylgalactosaminidase (endo-alpha-GalNAc-ase) catalyzes the hydrolysis of the O-glycosidic bond between alpha-GalNAc at the reduci...
产品描述2-O-(alpha-D-glucopyranosyl)glycerol is a glucosylglycerol consisting of an alpha-D-glucosyl residue attached at position 2 of glycerol via a glycosidic bond. It has a role as an osmolyte and a bacterial metabolite. It is a glucosylglycerol and an alpha-D-glucoside. ...
alpha-Amylases (1,4-alpha-D-glucan glucanhydrolase, EC 3.2.1.1) areendoenzymeswidely distributed in nature (Tiwari, Srivastava and Singh, 2015), which randomly hydrolyze alpha-1,4glycosidic bondswithin the starch molecule, acting onamyloseandamylopectin(Guzmán-Maldonado, Paredes-López and Biliader...
The glycosidic linkage is beta and 1-4 or 1-3, preferably 1-3. The linkage between the glycan and the amino acid may be alpha or beta, preferably alpha and is 1-. Core O-glycans have been described by Van de Steen et al. (1998), incorporated herein by reference. Mucin type O-...
