Description5-Methylthioribose 1-phosphate, also known as 1-phospho-5-S-methylthioribose or D-ribofuranoside, belongs to the class of organic compounds known as pentoses. These are monosaccharides in which the carbohydrate moiety contains five carbon atoms. 5-Methylthioribose 1-phosphate is an extremely weak basic (essentially neutral) compound (based on its pKa).
