Monday's Molecule #216

Last week's molecules were guanine and adenine. Everyone should have known these structures but only undergraduate Zhimeng Yu got it right! [Monday's Molecule #215].

You probably didn't memorize the structure of this week's molecule but you should be able to recognize it and check your answer in a textbook or on the web. What it is it? (I don't know why it has a gray background. Can anyone help? Fixed.)

Email your answers to me at: Monday's Molecule #216. I'll hold off posting your answers for at least 24 hours. The first one with the correct answer wins. I will only post the names of people with 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 email message.)
