Asparagusinsäure is a sulfur-containing carboxylic acid, which occurs in addition to its methyl ester in the vegetable asparagus, and their metabolites, 2- Propenthiosäure -S- methyl ester ( thioacrylic acid S- methyl ester ) and 3 - (methylthio) thiopropionic acid S- methyl ester for the strong odor of urine ( " asparagus Bach "," Bachus Spargelus "," asparagus Bacon " ) are responsible after eating asparagus. Both the formation of these degradation products as well as the ability to smell in the urine, pronounced genetically different in the population. Health consequences are not involved.

Asparagusinsäure is made of 3,3 '- Dichlorisobuttersäure and sodium disulfide ( generated in situ from sodium sulfide and sulfur available ) to produce.

The cooking of the asparagus Asparagusinsäure is thermally decomposed to form 1,2- Dithiacyclopenten and 1,2,3 - trithiane - 5-carboxylic acid:

Asparagusinsäure seems the plant to provide protection against fungal and bacterial infestation.
