Monday's Molecule #157

 
You need to pay close attention in order to identify this molecule correctly.

Post your answer in the comments. I'll hold off releasing any comments for 24 hours. The first one with the correct answer wins. I will only post correct answers to avoid embarrassment.

There could be two winners. If the first correct answer isn't from an undergraduate student then I'll select a second winner from those undergraduates who post the correct answer. You will need to identify yourself as an undergraduate in order to win. (Put "undergraduate" at the bottom of your comment.)

Some past winners are from distant lands so their chances of taking up my offer of a free lunch are slim. (That's why I can afford to do this!)

In order to win you must post your correct name. Anonymous and pseudoanonymous commenters can't win the free lunch.

Winners will have to contact me by email to arrange a lunch date.

UPDATE: The molecule is L-sedoheptulose 1,7-bisphosphate or L-altro-hept-2-ulose 1,7-bisphosphate. The D isomer is part of the pentose phosphate cycle and the Calvin cycle. The winner is Peter Monaghan.
