Monday's Molecule #35

This is a very common chemical found in most biochemistry labs. There's a very familiar form of this molecule and most of you will know it by the name of the salt. You need to supply the correct IUPAC name in order to win the prize.

There's an extremely obvious, but indirect, connection between this Monday's Molecule and Wednesday's Nobel Laureate(s).

The reward (free lunch) goes to the person who correctly identifies the molecule and the Nobel Laureate(s). Previous free lunch winners are ineligible for one month from the time they first collected the prize. There are no ineligible candidates for this Wednesday's reward since many recent winners haven't collected their prize. The prize is a free lunch at the Faculty Club.

  1. According to Wikipedia it is: 3,8-Diamino-5-ethyl-6-phenylphenanthridinium, a well known intercalative dye that binds to nucleic acids. Commonly used as the bromide salt. When irradiated with ultraviolet light the bound dye fluoresces intensely in the reddish-orange wavelengths. Therefore my pick for the associated Nobel has to be: James D. Watson, Francis H. C. Crick, & Maurice H. F. Wilkins, Nobel Prize in Physiology or Medicine, 1962

    "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material"

    N.B., regular readers of Sandwalk will realize that this was foreshadowed by Larry's telegram image from the Wellcome Trust (last week). Since I spent seven years working closely with Larry in graduate school (I was one of the four Ph.D. students he has mentored over the years) and subsequently co-taught a course with him, and co-authored a textbook, and we will soon be teaching another course and preparing a new version of our book together, perhaps I should disqualify myself from this weekly contest? On the other hand, it is a FREE lunch (and I can only claim one per month)!

  2. You win a free lunch. I'll even let you order an alcoholic beverage since you recognized the significance of the telegram. (No single malt scotches.)

    On the other hand, you missed this.

  3. Oops, I almost forgot. You can only collect your free lunch next week since I'll be in Ottawa this Thursday.
