Monday's Molecule #53

This is a simple one. All you have to do is give the correct name of the residue in the middle of the picture.

There's a direct connection between this molecule and Wednesday's Nobel Laureate(s). Your task is to figure out the significance of today's molecule and identify the Nobel Laureate(s) who are responsible for that significance. (Hint: There's also a connection to last week's lecture in biochemisty.)

The reward goes to the person who correctly identifies the molecule and the Nobel Laureate(s). Previous winners are ineligible for one month from the time they first collected the prize. There are three ineligible candidates for this week's reward. The prize is a free lunch at the Faculty Club.

Send your guess to Sandwalk (sandwalk(at) and I'll pick the first email message that correctly identifies the molecule and the Nobel Laureate(s). Correct responses will be posted tomorrow along with the time that the message was received on my server. I may select multiple winners if several people get it right.

Comments will be blocked for 24 hours. Comments are now open.

UPDATE: There is no winner this week. Nobody got the residue and nobody guessed the name of the Nobel Laureate(s).


  1. better late than never but isnt it phosphoserine with Fischer/Krebs.

  2. I think that it is phosphothreonine. The green rods must be go to carbon atoms. I don't think that hydrogens are shown anywhere. So, the carbon with the phosphate on in has one rod coming off, so it must be a CH3 as in threonine. If you look to the right and toward the screen you see two of these coming from a green fork. This is probably the R-group of a valine, again without hydrogens, with the alpha-carbon being hidden.

    I agree with Fischer/Krebs.

  3. Both of you are correct. It wasn't that hard, was it?
