As we know, a variety of receptors on cell surface and membrane bound proteins from mammal animals are heavily glycosylated. These carbohydrate receptors may be useful for the delivery of specific molecules through cell membrane into cytosol. For example, GalNAc receptor is currently popular in the delivery of siRNA molecules for the discovery of oligonucleotide drugs. The other receptors for mannose, fucose, galactose, sialic acid, etc. may be also useful for the delivery of mannose, galactose related molecules into the cell mediated through endocytosis by the cell. Therefore, the functions of carbohydrates are still mysteries besides adhesion between cells. We offered a variety of functional carbohydrates for your research purposes.
