My favorite vegetable is asparagus which is good because it's very healthy. The only thing I would change about asparagus is the way that it makes the urine of the people who eat it stink. Curious about the phenomena, I found an article on Occurrence of S-methyl thioesters in urines of humans after they have eaten asparagus that had been published in an issue of Science in 1975. Its author said:
Gas chromatography-mass spectrometry was used to determine the odor-causing agent (or agents) present in the urines of humans after they have eaten asparagus. S-Methyl thioacrylate and S-methyl 3-(methylthio)thiopropionate were identified from methylene chloride extracts of such urines and appear to be the odor-causing compounds. Methanethiol, the previously reported odor-causing agent, was not detected in these methylene chloride extracts.
It certainly sounds like S-Methyl thioacrylate and S-methyl 3-(methylthio)thiopropionate are the culprits. I think the next step important step is to produce a sort of asparagus-urine-stink prophylactic. Kind of like Beano.
