Sweet success in targeting sugar molecules to cells in living animals
... such as enzymes, whose function can be studied by purifying and analyzing individual molecules. Despite the promise of these studies, researchers faced a major challenge in finding the means to target sugars with specific markers for biological study to the surface of cells. Sugars are synthesized by complex ...Tobacco promising factory for biopharmaceuticals
