Used in metabolic labeling studies to trace fucose metabolism in cells, particularly for investigating protein glycosylation. Enables precise tracking of fucosylated glycans in biological systems due to the stable ¹³C isotope label. Applied in research on immune response, cell signaling, and host-pathogen interactions where fucosylation plays a critical role. Supports NMR and mass spectrometry analysis for detailed structural and dynamic studies of glycoconjugates.
