General description
Tetrahydrobiopterin is a natural cofactor for phenylalanine hydroxylase, tyrosine hydroxylase, tryptophan hydroxylase, nitric oxide synthase and alkylglycerol monooxygenase.
Application
(6R)-BH4 has been used as a buffer component for assaying tyrosine hydroxylase enzyme activity in mouse brain tissues. (6R)-BH4 has also been identified as an activator compound from a LOPAC library screen using a fluorogenic α-glucosidase assay.
Biochem/physiol Actions
Lack of tetrahydrobiopterin may cause hyperphenylalaninemia. Diseases like, Parkinson′s, autism, depression and Alzheimer′s shows low concentration of tetrahydrobiopterin in the cerebrospinal fluid. This coenzyme participates in dopamine (DA) synthesis.
Features and Benefits
This compound is featured on the Dopamine, Norepinephrine and Epinephrine Synthesis and Nitric Oxide Synthases pages of the Handbook of Receptor Classification and Signal Transduction. To browse other handbook pages, click here.
Preparation Note
(6R)-5,6,7,8-Tetrahydrobiopterin dihydrochloride ((6R)-BH4 ) is soluble in oxygen free water at 19.60 - 20.40 mg/ml and yields a clear to slightly hazy, colorless to faint yellow solution.

How should a solution of (6R)-5,6,7,8-tetrahydrobiopterin (hydrochloride) be stored? How long is it good for?
1 answer-
Tetrahydrobiopterin reacts with oxygen, particularly in neutral and alkaline solutions. The product should be reconstituted in oxygen-free water. Tetrahydrobiopterin solutions become yellow but are stable for several weeks at -20°C when prepared at 20-40 mg/mL in 0.1 N HCl.
