Catecholamines 92-105 tyrosine 3-monooxygenase Coturnix japonica 44-64 10210165-1 1999 Tyrosine hydroxylase (TH) activity, the rate-limiting step in the synthesis of catecholamines, was quantified in the preoptic area-hypothalamus of adult male Japanese quail by a new assay measuring the tritiated water production from 3,5-[3H]-L-tyrosine.
