UniProt position 50-56

4-Carboxybutyl N-acetyl-α-D-galactosaminide

The DBCO group reacts with azide-functionalized partners via copper-free strain-promoted azide-alkyne cycloaddition (SPAAC)

UniProt position 53-56

serving as a model glycoamino acid for glycopeptide synthesis and glycosidase/lectin studies

PE431000: β-Gal-PEG3-Alkyne label-new UniProt position 50-56C15H26O9 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
