Document Summary

Monoamine: contain a single amine group (-nh2) group. Nt vs. hormone: hormones are released into the blood stream by adrenal glands. Catecholamine nts were first discovered in the ans (cannon 1921) Sympathin (ne in 1964) released upon stimulation of the sympathetic nerves. Ne and epi are related to the stress response. Epi is mostly known as a hormone released by the adrenal medulla. Tyrosine is an amino acid derived from proteins and liver. Tyrosine hydroxylase (th) is the rate limiting enzyme in catecholamine synthesis. In da neurons, the final step involves the formation of dopamine from l3,4 dopa by the enzyme aadc. Type of neuron is determined by what enzymes are present in that neuron. Th turns into dopa, the precursor to dopamine. Ne and epi neurons and chromaffin cells of the adrenal medulla contain the enzyme dopamine beta hydroxylase. In ne cells, dbh is found inside vesicles.
