Thiamines are compounds containing a thiamine moiety, which is structurally characterized by a 3-[(4-Amino-2-methyl-pyrimidin-5-yl)methyl]-4-methyl-thiazol-5-yl backbone. Oryzenin is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Oryzenin can be found in rice, which makes oryzenin a potential biomarker for the consumption of this food product.
