Metabolite Identification
Common Name5-Methylthioribose
Description5-Methylthioribose (CAS: 23656-67-9) belongs to the class of organic compounds known as pentoses. These are monosaccharides in which the carbohydrate moiety contains five carbon atoms. 5-Methylthioribose is an extremely weak basic (essentially neutral) compound (based on its pKa). 5-Methylthioribose exists in all living organisms, ranging from bacteria to humans. In humans, 5-methylthioribose is involved in the metabolic disorder called hypermethioninemia. Outside of the human body, 5-methylthioribose has been detected, but not quantified in, several different foods, such as alaska wild rhubarbs, common verbena, greenthread tea, pasta, and Irish moss. This could make 5-methylthioribose a potential biomarker for the consumption of these foods. 5-Methylthioribose is a metabolite of 5-methylthioribose-1-phosphate. It is a substrate of methylthioribose kinase (EC 2.7.1.100) in the methionine metabolism pathway (KEGG). It can be found in Escherichia (PMID: 4203512 ).
