Motherboard hat einen etwas infantilen, aber dennoch insgesamt interessanten Artikel über den Duft von Urin nach einer ordentlichen Portion Spargel. Ich liebe Spargel.
After eating asparagus, your pee can smell pretty gross. Some people can smell asparagus-pee, while others can’t, and this difference is caused by a difference in your DNA! This issue is not quite that simple, as not everyone produces smelly asparagus-pee after eating asparagus […]
The asparagus-pee molecules that you smell come mostly from the breakdown of a molecule known as asparagusic acid, which is present naturally in asparagus. When your body breaks down asparagusic acid it forms a wide variety of chemicals, all of which contain sulfur! […]
Aside from sulfur, the thing that all these smelly asparagus-pee chemicals have in common is that they are “light” enough (a.k.a. they are “volatile”, which means they have a relatively low boiling point) that they can float up into the air and into your nose. That is partly why asparagus doesn’t smell like asparagus-pee, because asparagusic acid is not volatile (remember that word). In fact, asparagusic acid boils above 300 °C (>600 °F), so there is no way any of it gets into your nose!
