Pointers on Web Destinations
Friends & Students!
On occasion, I will be pointing out a few WWW links to you. Many of these
links, and many more, can be found in the "Web Destinations" section of
the course web site.
All of the common amines have unpleasent smells. For example, the amine
formed by having three methyl groups attached to the nitrogen,
(CH3)3N, is called trimethyl amine and is the
compound responsible for the smell of dead fish. Two other compounds named
putracine (1,4-butanediamine) and cadaverine (1,5-pentanediamine)
are responsible for the smell of rotting flesh.
Interestingly, some of these bad smelling amines show up where one might
least expect them. It turns out that not all flowers smell like roses!
Some flowers smell like "a rotting carcass." Take a look at the unusual
and quite interesting site on
(Two words I never thought to combine in my life.)
What makes a molecule smell? Fascinating question. Take a look at Dave
Bradley's article "Blowing the theory of how we smell" published in
the web publication
to get an idea about current hypotheses.
As always, enjoy, RG.
How to find the article
"Blowing the theory of how we
smell": Go to the web site of
and search for "smell".
