General Description

Gal beta(1-3)GlcNAc beta(1-3)Gal beta(1-4)Glc-beta-pNP is a chemical compound that consists of a complex carbohydrate structure linked to a chromogenic substrate, p-nitrophenyl. It is often used as a substrate in enzyme assays to study the activity of glycosyltransferases, which are enzymes involved in the synthesis of glycoproteins and glycolipids. The structure of the compound consists of specific sugar residues linked in a particular sequence, which makes it a useful tool for studying the substrate specificity and enzymatic activity of glycosyltransferases. The p-nitrophenyl group at the end of the compound allows for easy detection and quantification of the enzymatic reaction, making it a valuable tool in biochemical research.

A convenient synthesis of lacto-N-biose I [β-D-Galp-(1 → 3)-β-D-GlcpNAc] linkd oligosaccharides from phenyl O-(tetra-O-acetyl-β-D-galactopyranosyl)-(1 → 3)-4,6-di-O-acetyl-2-deoxy-2-phthalmido-1-thio-β-D-glucopyranoside

The synthesis of two tetrasaccharides and one trisaccharide containing lacto-N-biose I (β-D-Galp(1 → 3)-β-D-GlcpNAc) as their terminal unit was accomplished through development and utilization of a key glycosyl donor, namely, phenyl O-(2,3,4,6-tetra-O-ace
