WebThe high correlation between adrenaline release and disappearance rates of T3 and T4 after trauma suggests that adrenaline may in some way be connected to the fall in serum T3 and T4 concentrations following major trauma. The results further accord with the suggested role of T3 as a false neurotransmitter. L-Tyrosine or tyrosine (symbol Tyr or Y) or 4-hydroxyphenylalanine is one of the 20 standard amino acids that are used by cells to synthesize proteins. It is a non-essential amino acid with a polar side group.
