Melatonin

Melatonin, 5-methoxy-N-acetyltryptamine, is a hormone produced by pinealocytes in the pineal gland (located in the brain) and also by the retina and GI tract.

It is referred to by some biochemists and human physiologists as the master hormone, because it regulates the production of most human hormones, both paracrine and endocrine.
