Influences Sexual Development\u003cbr\u003eMelatonin: Synthesis, Secretion and Receptors\u003cbr\u003eThe precursor to melatonin is serotonin, a neurotransmitter that itself is derived from the amino acid tryptophan.\u003cbr\u003eWithin the pineal gland, serotonin is chemically changed to yield melatonin.\u003cbr\u003eSynthesis and secretion of melatonin is dramatically affected by light exposure to the eyes.\u003cbr\u003eThe fundamental pattern observed is that serum concentrations of melatonin are low during the daylight hours, and increase to a peak during the dark.\u003cbr\u003eThe mechanism behind this pattern of secretion during the dark cycle is that activity of the rate-limiting enzyme in melatonin synthesis - serotonin N-acetyltransferase (NAT) - is low during daylight and peaks during the dark phase.\u003c\/p\u003e\u003cp\u003eTABLE OF CONTENT\u003cbr\u003eIntroduction\u003cbr\u003eChapter 1 The Pineal Gland\u003cbr\u003eChapter 2 Pineal Gland Function\u003cbr\u003eChapter 3 Melatonin and Its Functions\u003cbr\u003eChapter 4 Pineal Cells and Endocrine Function\u003cbr\u003eChapter 5 The Third Eye\u003cbr\u003eChapter 6 Pineal Gland and Third Eye\u003cbr\u003eEpilogue\u003c\/p\u003e","brand":"Kenneth Kee","offers":[{"title":"Default Title","offer_id":47070426759408,"sku":"2940153789750","price":2.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940153789750_p0.jpg?v=1764056342","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940153789750","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
