Triantennary β-D-GalNAc pentaethyleneglycol (PEG5) carboxylic acid ligand
32 / An α-D-mannose ligand equipped with a terminal carboxylic acid through a hydrophilic PEG3 spacer
serving as a model glycoamino acid for glycopeptide synthesis and glycosidase/lectin studies
UniProt position 53-56
C17H31NO11 / 425
PE431000: β-Gal-PEG3-Alkyne label-new Triantennary β-D-GalNAc pentaethyleneglycol (PEG5) carboxylicC15H26O9 350. 36 A D galactose ligand equipped with a terminal alkyne through a hydrophilic PEG3 spacer. The alkyne couples to azide functionalized partners via copper catalyzed azide alkyne cycloaddition (CuAAC), forming stable 1,2,3 triazole linkages. This compound provides a anomeric galactose building block for glycoconjugate synthesis, glycomimetic research, and the construction of probes for galactose recognizing proteins, including galectins
