Most authorities feel that the compound that causes the odor in urine after consumption of asparagus is methylmercaptan, which is a sulfur-containing derivative of the amino acid, methionine. This is disputed by a few individuals who claim that the odiferous compound is asparagine-amino-succinic-acid monoamide, which is derived from the amino acid, asparagine. In either case, the product is formed as a derivative during the digestion and subsequent breakdown of beneficial amino acids that occur naturally in asparagus.
I think it is because we have not learned yet how to truly accept asparagus for what they are...
our equals in this confused world. Once we do, our chamber-pots shall be odor free.
