Web15 sep. 2011 · Abstract. BH4 (6R-L-erythro-5,6,7,8-tetrahydrobiopterin) is an essential cofactor of a set of enzymes that are of central metabolic importance, including four aromatic amino acid hydroxylases, alkylglycerol mono-oxygenase and three NOS (NO synthase) isoenzymes. Consequently, BH4 is present in probably every cell or tissue of higher … WebFirst, NaBH4 is not so reactive and the reaction is usually carried out in protic solvents such as ethanol or methanol. The solvent has two functions here: 1) It serves as the source of a proton (H +) once the reduction is complete. 2) The sodium ion is a weaker Lewis acid than the lithium ion and, in this case, the hydrogen bonding between the ...
