The molecule was progesterone and the official complete IUPAC name is 8S,9S,10R,13S,14S,17S)-17-acetyl-10,13-dimethyl-1,7,8,9,10,11,12,13,14,15,16,17-dodecahydro-2H-cyclopenta[a]phenanthren-3(6H)-one. Progesterone is a female sex hormone that controls the maintenance of the endometrial lining during pregnancy.
The Nobel Laureate who worked out the structure of progesterone was Johann Butenandt.
Dara Gilbert of the University of Waterloo was the first person to get the correct answers using the abbreviated IUPAC name. This week there's a special award to Anne Johnson of Ryerson University for supplying the complete IUPAC name as well as the most complete description of the function of progesterone and additional information on the Nobel Laureate.
Name this molecule. Include the IUPAC name and a brief description of its function.
One Nobel Laureate got the prize for contributions to organic chemistry, including working out the structure of this molecule.
The first person to identify the molecule and the Nobel Laureate, wins a free lunch. Previous winners are ineligible for six weeks from the time they first won the prize.
There are seven ineligible candidates for this week's reward: Òscar Reig of Barcelona, Maria Altshuler of the University of Toronto, Mike Fraser of the University of Toronto, Jaseon Oakley of the University of Toronto, Bill Chaney of the University of Nebraska, Ian Clarke of New England Biolabs Canada in Pickering ON, Canada and Dima Klenchin of the University of Wisconsin at Madison.
Dima has donated his 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.
Send your guess to Sandwalk (sandwalk (at) bioinfo.med.utoronto.ca) and I'll pick the first email message that correctly identifies the molecule(s) 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.
