Last week's molecule was photosystem I (PSI). Mikkel Rasmussen was the only one to get it right [Monday's Molecule #191].
I thought of this week's molecule while I was in Los Angeles last week. We got to sample some excellent examples of cuisine that's hard to find in Toronto. You need to supply the common name AND the formal IUPAC name.
Post your answer as a comment. I'll hold off releasing any comments for 24 hours. The first one with the correct answer 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. Please try and beat the regular winners. Most of them live far away and I'll never get to take them to lunch. This makes me sad.
Comments are now open.
UPDATE: The molecule is capsaicin. It's responsible for the "hot" taste in chili peppers (Capsicum sp.). The IUPAC name is usually given as 8-methyl-N-vanillyl-trans-6-nonenamide (e.g. Wikipedia) and this is the answer supplied by Seth Kasowitz. He's a winner! However, there's a more correct IUPAC name, N-(4-hydroxy-3-methoxybenzyl)-8-methylnon-6-enamide, and this was the IUPAC name in the response from Bill Gunn. He's also a winner! The winners should contact me by email.

-Seth Kasowitz
Molecule #192 is Capsaicin, or 8-Methyl-N-vanillyl-trans-6-nonenamide.
ReplyDeleteCAPSAICIN, IUPAC name N-[(4-hydroxy-3-methoxyphenyl)methyl]-8-methylnon-6-enamide
ReplyDeleteI have had some of this today both from habaneros and Portuguese style red peppers all grown in our own yard here in South Ontario.
8-Methyl-N-vanillyl-trans-6-nonenamide

How weird, I was looking at this molecule just yesterday! It's Capsaicin.
ReplyDeleteI thought of this week's molecule while I was in Los Angeles last week. We got to sample some excellent examples of cuisine that's hard to find in Toronto.
ReplyDeleteWhat, there is no spicy food in Toronto?
That would be Capsaicin, and the IUPAC name would be 8-Methyl-N-vanillyl-trans-6-nonenamide
ReplyDeleteOk, sorry, Capsaicin with a (real) IUPAC name of (E)-N-[(4-hydroxy-3-methoxyphenyl)methyl]-8-methylnon-6-enamide
ReplyDeleteThe substance that makes you believe, your food is burning hot...
ReplyDeleteAnd birds don't feel it, so for them your jalapeno is sweet...
Capsaicin, i.e. 8-Methyl-N-vanillyl-trans-6-nonenamide
