Azido-modified nucleotide sugar donor substrate for fucosyltransferases; enables bioorthogonal click chemistry labeling of fucosylated glycans via azide–alkyne cycloaddition (CuAAC/SPAAC); used for glycan imaging and glycoproteomic profiling
Activated sugar nucleotide donor substrate for mannosyltransferases; essential for N-linked glycoprotein biosynthesis, GPI-anchor assembly, and ascorbic acid (vitamin C) biosynthesis in plants
Activated nucleotide sugar donor substrate for fucosyltransferases (FUTs); essential for biosynthesis of fucosylated glycans including Lewis antigens, ABO blood group determinants, and core fucosylation of N-glycans
