Metabolite Identification
Common Name(S)-N-Methylsalsolinol
Description(S)-N-Methylsalsolinol, also known as 1,2-ddtiq, belongs to the class of organic compounds known as tetrahydroisoquinolines. These are tetrahydrogenated isoquinoline derivatives (S)-N-Methylsalsolinol has been detected, but not quantified in, a few different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), and domestic pigs (Sus scrofa domestica). This could make (S)-N-methylsalsolinol a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on (S)-N-Methylsalsolinol.
