Glucodigifucoside is primarily used in biochemical research for studying glycosylation processes and cell surface interactions. It serves as a substrate in enzymatic assays involving glycosidases and glycosyltransferases, helping scientists understand carbohydrate metabolism and related pathways. Due to its structural complexity, it is also utilized in the development of synthetic antigens and vaccine candidates, particularly in targeting pathogens that interact with fucose-containing glycans. Additionally, it has potential applications in the design of glycomimetic drugs aimed at modulating immune responses or blocking microbial adhesion.
