The conformational space of the glycosidic linkage was studied by calculating two virtual dihedrals connecting the successive glucose units for the 2000 structures saved during the two simulations. Three preferred regions for alpha 1-4 glycosidic linkage were found in both the simulations. The use of...
beta-Amylases (1,4-D-glucan maltohydrolase, EC 3.2.1.2) are exoenzymes that hydrolyze the alpha-1,4 glycosidic bonds of starch, from the non-reducing end, releasing mainly units of maltose with the inversion of the configuration of anomeric carbon from alpha to beta. These enzymes act on...
α-amylase catalyses the hydrolysis of α-1,4 glycosidic linkage in oligosaccharides. It plays a crucial role in the initial digestion of starch, glycogen and polysaccharides. Elevated levels of amylase in serum is linked to acute pancreatitis. ...
carbon-3 of Gal to form an α-2,3 glycosidic linkage, or to the hydroxyl group attached to carbon-6 to form an α-2,6 glycosidic linkage.1ST6Gal I generates a α-2,6 linkage of sialic acid on the non-reducing, terminal Galβ1 4GlcNAc residues of oligosaccharides and glycoconjugates....
Depending on the spatial structure of the glycosidic linkage between glucose, arbutin forms two epimers: α-arbutin and β-arbutin. C. Alpha arbutin VS beta arbutin Main Function 1. Alpha-arbutin Skin lighten,Whiten and dispell fleck, 2. Alpha-arbutin Prevent ultraviolet radiation....
3.1 Description Ajugose is a hexasaccharide that is verbascose which has an additional unit of alpha-D-galactopyranose attached by a 1->6 glycosidic linkage to the terminal galactosyl residue. It is a hexasaccharide and a raffinose family oligosaccharide. It derives from a verbascose....
Depending on the spatial structure of the glycosidic linkage between glucose, arbutin forms two epimers: α-arbutin and β-arbutin. C. Alpha arbutin VS beta arbutin. Main Function 1. Alpha-arbutin Skin lighten,Whiten and dispell fleck, 2. Alpha-arbutin Prevent ultraviolet radiat...
The β-amylases also hydrolyze amylose in an exo-fashion with inversion, the prefix β referring to the anomeric configuration of the maltose product that is released, as opposed to the stereochemistry of the substrate glycosidic linkage. Analogous to the inverting cellulases, Aspergillus glucoamylase...
wherein Gal represents a galactose residue, Cer represents a ceramide residue and α1→4 represents an α1-4 glycosidic linkage. In the present invention, the enzyme having an activity to transfer a galactose residue from a galactose donor to C4 position of galactose residue of lactosylceramide...
This Example demonstrates that invention is compatible with oligosaccharides other than cellobiose. It is of interest that the more acid labile glucosel 4 glucose intraglycosidic α-linkage was compatible with the reaction conditions. EXAMPLE 5a ...
