WebDec 24, 2014 · Dec 24, 2014 Yes, there are 16 individual sugar names. Explanation: An aldohexose has four chiral centres. So there are 24 = 16 optical isomers. The 8 D-aldohexoses are shown below. (From sandwalk.blogspot.com) Their mirror images are the L-aldohexoses, the other 8 of the 16. Their names are L-allose, L-altrose, L-glucose, etc. WebThe rule of thumb is: chiral carbon centers are carbon atoms that are attached to four different substituents, that are placed at the corners of a tetrahedron.
