WebGlucose has an aldehyde group (-CHO) on carbon atom number one and is therefore called an “aldose,” also it has six carbon atoms (a hexose) so it can be called an “aldohexose.” The reactive group on fructose, however, is a ketone group (-C=0) on carbon number two. It is therefore called a “ketose” or a “ketohexose.”

WebExcept for the first and the last carbon atom, the other four carbon atoms in glucose are chiral. Thus, glucose has 2 4 =16 isomers.
