There are four chiral carbon atoms in the open-chain form of glucose.


The structure of glucose with its numbering is

There are no internal mirror planes, so every carbon atom is different.

The four chiral centres (with their attached groups) are:

  1. #"C2 (OH,C1, C3, H)"#
  2. #"C3 (OH, C2, C4, H)"#
  3. #"C4 (OH, C3, C5, H)"#
  4. #"C5 (OH, C4, C6, H)"#
