Post your answer in the comments. I'll hold off releasing any comments for 24 hours. The first one with the correct answers wins. I will only post mostly correct answers to avoid embarrassment. The winner will be treated to a free lunch.
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 HMG-CoA or 3-hydroxy-3-methylglutaryl Coenzyme A. The enzyme is HMG-CoA reductase, a key enzyme in the pathway leading to synthesis of cholesterol. Competitive inhibitors of this enzyme are used to reduce blood cholesterol levels by blocking synthesis of endogenous cholesterol. The most common inhibitors are the statins such as atorvastin (Lipitor) and lovastatin (Mevacor). The winner is undergraduate Sean Ridout.

1. I watched Mission: Impossible - Ghost Protocol on a recent flight from San Diego to Toronto. You should only do this when you've exhausted all other options.

HMG-CoA. The enzyme is HMG-CoA reductase, and statins come to mind as inhibitors e.g. atorvastatin (Lipitor).

Crappy escapist movies are the ideal entertainment for long flights. I mean, if the movie was any good, it would deserve better than seeing it on a tiny screen, against roaring background noise, while seated in a cramped seat, right?
I don't know if it's exactly right and don't have time to chack but it would seem to make sense:
1. The molecule 3-hydroxy-3-methylgutaryl-CoA, which implies that the enzyme is
2. 3-hydroxy-3-methyl-glutaryl-CoA reductase, which in turn means that the task of identifying important competitive inhibitor is poorly defined because there are many of them. I think most statins are. So I'll name one that used first:
3. Lovastatin.
Larry, I sent you an email couple days ago. Did you get it?
(a) The molecule is HMG-CoA or 3-hydroxy-3-methylglutaryl-coenzyme A.(b) The most important enzyme that uses it as a substrate is HMG-CoA reductase or 3-hydroxy-3-methyl-glutaryl-CoA reductase.(c) One important competitive inhibitor of this enzyme is (3R,5R)-7-[2-(4-fluorophenyl)-3-phenyl-4-(phenylcarbamoyl)-5-propan-2-ylpyrrol-1-yl]-3,5-dihydroxyheptanoic acid or atorvastatin (Lipitor's active ingredient), from the family of inhibitors known as statins.
- UofT undergraduate
The nucleotide end puzzled me. Shouldn't there be a third phosphate at the 3' position?
Larry, can't you start holding contests that will give stupid people a chance to have lunch with you too? :D
Yes, I know this won't make it into comments... I'm just sayin'. :)
Anybody, even stupid people :-) , can have lunch with me. All you have to do is ask.
The contest is for those who want to have lunch AND they want me to pay for it!
