Chemical Information
FooDB NameDihydrobiopterin
DescriptionDihydrobiopterin, also known as BH2, belongs to the class of organic compounds known as biopterins and derivatives. These are coenzymes containing a 2-amino-pteridine-4-one derivative. They are mainly synthesized in several parts of the body, including the pineal gland. Dihydrobiopterin is an extremely weak basic (essentially neutral) compound (based on its pKa). Dihydrobiopterin exists in all eukaryotes, ranging from yeast to humans.
