Document Summary
Tyrosine is converted to l-dopa by the enzyme tyrosine hydroxylase (th) Th is rate-limiting step in da synthesis. L-dopa is converted to da by an enzyme. As far as dopamine receptors, were not gonna get into them too much. Even though not doing as much, its still important behaviorly. What we need to treat parkinsons is more dopamine. Ta is rate limiting the production of dopamine. 5-ht (know it means serotonin) seems to be involved in every psychological function. Yet total destruction of 5-ht in animals does not result in death. Some of most useful drugs in psychiatry alter 5-ht. Agonists at particular 5-ht receptors are potent hallucinogens. 5-ht is thought to be involved in diverse functions such as temp. Sert=serotonin transporter reuptake tryptophan (glu) is an excitatory amino acid (eaa) nt involved in dynamic info processing activities. 9 projection systems and 13 different receptors, we still don"t know everything about it.
