Phenylalanine to tyrosine conversion
WebHow is phenylalanine converted to tyrosine? To enter the tyrosine pathway, phenylalanine is converted into tyrosine by the enzyme phenylalanine hydroxylase, which has tetrahydrobiopterin as a cofactor. Deficiency of the enzyme or of its cofactor causes accumulation of phenylalanine in the body fluids and tissues. http://www.outthinkingparkinsons.com/articles/dopamine-biochemistry
