Use the fischer projections in the figure of common monosaccharides to explain the difference between the structures of these compounds predict what an enzyme would have to do to convert glucose into fructose, or vice versa. Compare alpha and beta fructose: the beta position is defined as the -oh being on the same side of the ring as the c # 6 in the ring structure this results in a upwards projection for the -oh on carbon # 2.
