Yeah, everybody knows that eating asparagus can cause a rather unpleasant smell in your urine. I didn't know that. Oh, that's right. Not everybody is an excretor of the odoriferous compound. And not everybody can perceive the odor, either. Both those traits are genetic 1. But what causes it? well, that's a good question. No one’s really sure. We do know that the pungent 2 chemical is some kind of sulfur 3 based compound. But scientists have been trying to find the exact identity of it since the 1890s.More recently, researchers found out that the smell is actually caused by a malodorous cocktail 4 of six sulfur containing compounds.
