3-Ketopentoses

The article only lists ketopentoses with the C=O at position 2. But aren't there also 3-ketopentoses, H(CHO)₂(CO)(CHO)₂H? If I am not mistaken, there should be a pair of mirror-image stereoisomers, and a third stereoisomer that is its own mirror image (rotated 18 degrees). is that right? What are their names? --Jorge Stolfi (talk) 04:57, 10 January 2011 (UTC)[reply]
