Description

4A-Carbinolamine tetrahydrobiopterin, also known as 6,7-dihydrobiopterin or 1,3,5-trihydroxybenzene, 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. 4A-Carbinolamine tetrahydrobiopterin is a moderately basic compound (based on its pKa). 4A-Carbinolamine tetrahydrobiopterin exists in all living organisms, ranging from bacteria to humans. 4a-Carbinolamine tetrahydrobiopterin was first documented in 1990 (PMID: 2225712). A 4a-Carbinolamine tetrahydrobiopterin that has R configuration at position 6 and in which the 1,2-dihydroxypropyl substituent has 1R,2S configuration (PMID: 12860038) (PMID: 14565560) (PMID: 8128228) (PMID: 16454126).
