residue which is attached to an amino group thereof by a coupling other than a direct N-glycosidic bond, and additionally, when it is a condensation product of a carboxyl group containing sugar and a peptide with less than 8 amino acid units, by a coupling other than a direct amide bond....

It is a derivative of cellobiose, a disaccharide composed of two glucose units linked by a β(1→4) glycosidic bond. ALPHA-D-CELLOBIOSE OCTAACETATE is commonly used as a protecting group for hydroxyl groups in organic synthesis. It plays a crucial role in the production of various ...
Phosphatase of potato readily hydrolyzes natural starch phosphates (potato amylopectin)3092 and synthetically prepared starch phosphates,3093 leaving glycosidic bonds intact. On the other hand, corn starch can be phosphorylated with Na2HPO4 in the presence of isoamylase.3094 Phosphorylases (EC 2.4 and 2.7...
The naturally-occurring α-1,6-branched α-1,4-glucans described, starch and glycogen, are very different depending on their content of 1,6-glycosidic branchings. This holds true, amongst others, with regard to solubility, transparency, enzymatic hydrolysis, rheology, gel formation and retrogradati...
By “glucosyl unit” is meant the residue resulting from the cleavage of sucrose, which is temporarily associated with the enzyme in the form of a β-glucosyl-enzyme and that is transferred to an acceptor comprising a hydroxyl moiety by forming a glycosidic bond with that hydroxyl moiety. ...
2′-Deoxyzebularine and its α-anomer have been efficiently synthesized with relatively high stereoselectivity by a modified procedure of the silyl method of the N-glycosidic bond formation. An SnCl4- catalyzed condensation of silylated pyrimidin ...

The reason for such a strong distortion of this cycle was the deviation from the unfavorable conformation that was blocked along the C1–C5 bond. The C2C1C5C4 torsion angle was 29.8°, while for an ideal bath conformation, this angle equals 0°. The conformation of the γ-lactone ring, ...
Structure determination of the α(1,3)-linked fucoidan backbone with the 1-4 linked sulfated fucosyl substitution of the OF1 oligosaccharide. (c) Overlay of 1H-1H COSY and 1H-1H NOESY spectra, showing the NOE across the glycosidic bond for hydrogens 1 and 4 of residues G and B. (d) ...
