Chemical Information
FooDB Name4-Methylthiazole
Description4-Methylthiazole belongs to the class of organic compounds known as thiazoles. These are heterocyclic compounds containing a five-member aromatic ring made up of one sulfur atom, one nitrogen, and three carbon atoms. 4-Methylthiazole is a green, nutty, and roasted meat tasting compound. 4-Methylthiazole has been detected, but not quantified in, several different foods, such as coffee and coffee products, asparagus (Asparagus officinalis), robusta coffees (Coffea canephora), nuts, and breakfast cereal. This could make 4-methylthiazole a potential biomarker for the consumption of these foods. 4-Methylthiazole, with regard to humans, has been linked to the inborn metabolic disorder celiac disease. Based on a literature review a significant number of articles have been published on 4-Methylthiazole.
