WebIn that case, mirroring is equivalent to a half-turn rotation. For this reason, there are only three distinct 3-ketopentose stereoisomers, even though the molecule has two chiral carbons. Distinct stereoisomers that are not mirror-images of each other usually have different chemical properties, even in non-chiral environments. WebNov 12, 2015 · The general structure of an aldopentose is We see that the molecule has three chiral carbons. The maximum number of stereoisomers is 2n, where n is the number of chiral carbons. Since n = 3 and 23 = 8, there are eight possible aldopentoses. Here are the structures of four of the aldopentoses.
