The conversion of phenylalanine to tyrosine is defect, phe accumulates and leads to brain damage. There are different degrees of severity, reflecting the spectrum of mutant genes. BH4, tetrahydrobiopterin, is co-enzym for the conversion of phe to tyrosine. BH4 can lower phe in some patients with milder forms of PKU.Product Name: tetrahydrobiopterinJohn F.
