Guanosine triphosphate (GTP) cyclohydrolase I (GCH1) catalyzes the conversion of GTP to dihydroneopterin triphosphate (H2NTP), the initiating step in the biosynthesis of tetrahydrobiopterin (BH4). Besides other roles, BH4 functions as cofactor in neurotransmitter biosynthesis. The BH4 biosynthetic pathway and GCH1

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.
