Studies in laboratory rats during the early 1970s linked saccharin with the development of bladder cancer in rodents. Both maltose and lactose contain a free anomeric carbon that can convert to an aldehyde functional group, so they are reducing sugars; they also undergo mutarotation. 40, pp. (Scheme 106).133 Saccharin assesses as amine source and tolerates a wide range of different functional groups. Wed 8:00am - 5:00pm. A linkage between two phosphates creates a phosphate anhydride.
