A 2-ketohexose has six carbon atoms (hexose) and a ketone functional group at the second carbon (2-keto). Each of the six carbon atoms can have a different group attached to it, which means there are potentially six chiral centers. However, the ketone functional group removes the chiral center at the second carbon. Therefore, there are five chiral centers in a 2-ketohexose.
