Sweden Academy of Sciences awarded E. Fischer in 1902 for his prediction of parentage of carbohydrates, the stereochemical elucidation of these highly stereogenic simple blocks, and, very importantly too, for their striking ability to adopt several forms, so that sugars can be drawn either linearly or as a five- (furanose) or a six-membered (pyranose) ring. To this major discovery in the field of natural molecules followed many efforts in analytical approaches, chemical modifications and synthesis. However, because mammals are able to biosynthesize only pyranosyl-containing conjugates and polymers, with the exception of nucleic acids, the scientific community was mainly attracted by...
