What is Melatonin?

Melatonin (Melatonine, short for MT) is one of the hormones secreted by the pineal gland. Melatonin belongs to the indole heterocyclic compound, and its chemical name is N-acetyl-5 methoxytryptamine, also known as pineal gland, melatonin, and melatonin. After the synthesis of melatonin, it is stored in the pineal gland, and the sympathetic nerve excites the pineal gland cells to release melatonin. The secretion of melatonin has an obvious circadian rhythm, the secretion is inhibited during the day, and the secretion is active at night.

Function

1. ① Effects on the brain: Melatonin taken up by the brain is concentrated in the midbrain and hypothalamus, which enhances the activity of brain pyridoxal kinase, thereby promoting the decarboxylation of glutamate to form γ-aminobutyric acid and the decarboxylation of 5-hydroxytryptophan to form 5-hydroxytryptamine. The increase in the content of these two inhibitory neurotransmitters has a regulating and sedative effect on the central nervous system.

2. ② Effects on the hypothalamus and pituitary gland: In addition to AVT, the pineal gland produces polypeptide substances such as thyrotropin-releasing hormone (TRH) and luteinizing hormone-releasing hormone (LRH), which are the same as those produced by the hypothalamus. After the injection of melatonin, gonadotropin (GnH) (FSH, LH) and melanocyte stimulating hormone (MSH) can be reduced, while growth hormone (GH) can be increased. After the pinealectomy, pituitary hypertrophy is caused, and the secretion of pituitary GnH (FSH, LH) and ACTH increases, while prolactin (PRL) and antidiuretic hormone (ADH) decrease.

3. ③Relationship with gonads: Pineal hormone has an inhibitory effect on the reproductive system. Clinically, pineal chief cell tumors can lead to delayed puberty, and in the case of pineal teratoma, due to the exclusion of the chief cells, it can be complicated by precocious puberty. Environmental light and sympathetic nerves can affect the function of the reproductive system by controlling the synthesis and release of pineal melatonin.

4. ④Relationship with the thyroid gland: When melatonin is given, the secretion of thyroid hormones decreases, which may be through inhibiting the release of hypothalamic TRH and the secretion of pituitary thyroid stimulating hormone (TSH), thereby inhibiting thyroid function.

5. ⑤Relationship with the adrenal cortex: Melatonin has a strong inhibitory effect on the adrenal cortex. When pineal extracts are injected into healthy people, their aldosterone secretion decreases and the excretion of 17 ketosteroids decreases.

6. ⑥Relationship with pancreatic islets: Pineal hormone can lead to lower blood sugar and increased glucose tolerance. I

7. n summary, the pineal gland can assist the pituitary gland in co-regulating endocrine function, which is important for maintaining the relative constancy of the body's internal environment and controlling certain endocrine functions, especially for the gonads.

Application

• 1. Melatonin removes spots and whitens the skin naturally: Melatonin can whiten the skin. It can regulate the endocrine system of the human body, remove dark spots, age spots, chloasma, pregnancy spots and pigmentation caused by sun exposure and radiation, whiten and moisturize the skin, and restore youthful style.

• 2. Effectively improve sleep: Appropriate supplementation of melatonin can effectively improve sleep quality.

• 3. Prolong life: Melatonin is the most important high-efficiency endogenous antioxidant in the brain, which has a protective effect on the brain. Therefore, melatonin is an important anti-aging hormone.

• 4. Maintain and enhance sexual function: Supplementation of melatonin can improve the sexual function of middle-aged and elderly people who have lost their libido due to aging, physical weakness, and decreased energy.
