Properties and stability
1. Basic properties
In living organisms it May be a precursor or intermediate of catecholamines. Para-hydroxylation of phenylalanine in vivo by meta-hydroxylase(For example, meta-hydroxylation is carried out before the formation of dopa, followed by decarboxylation to generate dopamine,dopamine). L-m-Tyrosine can penetrate the blood-brain barrier and decarboxylate into tyrosinem-Tyramine, which has the effect of stimulating dopamine receptors.
