Discoveries about NE, EPI, and DA have triggered lots of Nobel Prizes over various decades. This part presents A few of these discoveries, which affirm the continuing worth of catecholamine systems in science and medication.
Catecholamines are hormones that also function as neurotransmitters. The body provides them while in the Mind, nerve tissues, and adrenal glands. The adrenal glands are located just higher than the kidneys.
Tyrosine is created from phenylalanine by hydroxylation by the enzyme phenylalanine hydroxylase. Tyrosine is usually ingested straight from dietary protein.
This review was penned mainly dependant on experiments done in my laboratory. I apologize for not having experienced the Place to consult with the many other crucial contributions to this industry produced by various other investigators around the world.
