N2-Acetyl Acyclovir O-Dimethyl

Is Permethylation Strategy Always Applicable to Protein N-Glycosylation Study: A Case Study on the O-Acetylation of Sialic Acid in Fish Serum Glycans

. However, permethylation, the most common mass spectrometric analytical means, leads to the loss of O-linked acetyl groups in sialic acids. In this chapter, we demonstrated that O-acetylation of sialic acid in Atlantic salmon serum N-glycan can be well investigated

Characterization of Glycosaminoglycans by Capillary Electrophoresis

to a D-glucosamine (either N -sulfo or N -acetyl-d -glucosamine) residue. Both saccharide residues can be O -sulfonated at a variety of different positions, making these glycosaminoglycans structurally complex. Hyaluronic acid contains a simple repeating

Synthesis of Azido-Functionalized Carbohydrates for the Design of Glycoconjugates

of the carbohydrate derivative, or attached to a spacer arm. We describe here the syntheses of 2,3,4,6-tetra-O -acetyl-β-d -glucopyranosyl azide as well as 1-azido-3,6-dioxaoct-8-yl 2,3,4,6-tetra-O -acetyl-β-d -galactopyranoside and 1-azido-3,6-dioxaoct-8-yl
