Please give me a note on amino acid derivative hormones... please...

Hormones which are derived from the modification of amino acids are amine hormones.
Amine hormones are synthesized from the amino acids tryptophan or tyrosine. Example of a hormone derived from tryptophan is melatonin, which is secreted by the pineal gland and helps regulate sleep-wake cycle. Tyrosine derivatives include the thyroid hormones, as well as the catecholamines, such as epinephrine, norepinephrine. Epinephrine and norepinephrine are secreted by the adrenal medulla and play a role in the fight-or-flight response.
