Hi again Jan! thanks for that info - do you think the catecholamines are included in that two way thing too? Phenylalanine to tyrosine - as phenylalanine is an essential amino acid and we must get it from the diet I'm not so sure. DOPA decarboxylase to dopamine, would need a carboxylase enzyme to work the other way. Do you think there is some reverse flow traffic? I know we tend to see things in black and white, but sometimes things aren't so clear cut!!
