WebSo, all of these aldohexoses have four chiral centers, and that means they have two to the four, or 16 stereoisomers. Now, half of those are going to have to have this OH at the bottom on the right side, and the other half would be left. So, half of 16 is eight, and that's how we get to this idea that there are eight D-aldohexoses. Web4 feb. 2024 · 6. Drawing chair conformations of aldohexoses.
