Monday's Molecule #114: Winners

UPDATE: The molecule is streptomycin, 5-(2,4-diguanidino-3,5,6-trihydroxy-cyclohexoxy)- 4-[4,5-dihydroxy-6-(hydroxymethyl) -3-methylamino-tetrahydropyran-2-yl] oxy-3-hydroxy-2-methyl-tetrahydrofuran-3-carbaldehyde. Streptomycin inhibits protein synthesis in bacteria. The Nobel Laureate is Selman Waxman.

This week's winners are Bill Chaney of the University of Nebraska and Elvis Cela of the University of Toronto.

Identify this molecule and briefly describe its function. You must supply the common name and one of the the formal IUPAC names.

I'm looking for the Nobel Laureate who discovered this molecule.

The first person to identify the molecule and the Nobel Laureate wins a free lunch at the Faculty Club. Previous winners are ineligible for one month from the time they first won the prize.

There are seven ineligible candidates for this week's reward: Guy Plunket III from the University of Wisconsin, Deb McKay of Toronto, Maria Altshuler of the University of Toronto, David Schuller of Cornell University, Adam Santoro of the University of Toronto, Dima Klenchin from the university of Wisconsin, and Alex Ling from the University of Toronto.

Dima has offered to donate a free lunch to a deserving undergraduate so I'm going to continue to award an additional free lunch to the first undergraduate student who can accept it. Please indicate in your email message whether you are an undergraduate and whether you can make it for lunch.


Nobel Laureates
Send your guess to Sandwalk (sandwalk (at) and I'll pick the first email message that correctly identifies the molecule and names the Nobel Laureate(s). Note that I'm not going to repeat Nobel Prizes so you might want to check the list of previous Sandwalk postings by clicking on the link in the theme box.

Correct responses will be posted tomorrow. I reserve the right to select multiple winners if several people get it right.
