I-Melatonin - 73-31-4

Ukusetshenziswa: isetshenziselwa imithi kanye nemikhiqizo yokunakekelwa kwezempilo, ingathuthukisa ukusebenza kwamasosha omzimba womuntu, ivimbele ukuguga futhi ibuyisele intsha, futhi "iphilisi lokulala" lemvelo.

I-Melatonin (eyaziwa nangokuthi i-melatonin, i-melakonin, i-melatonin, i-pineal hormone) iyi-hormone ye-amine ekhiqizwa i-pineal gland yezilwane ezincelisayo kanye nabantu, engenza iseli elikhiqiza i-melanin likhanye, yingakho igama elithi melatonin.

I-pineal hormone, eyaziwa nangokuthi i-melatonin, i-hormone ekhiqizwa amaseli e-pineal. Isakhiwo sayo samakhemikhali yi-5-methoxy-N-acetyltryptamine. Umsebenzi wayo wokuphila ukuvimbela i-gonad, indlala yegilo, indlala ye-adrenal, indlala ye-parathyroid kanye nemisebenzi ye-pituitary gland, ukuvimbela ukukhula kocansi kwezingane nokunciphisa ukukhishwa kwe-pituitary melanotropin.

Futhi inomsebenzi wohlelo lwezinzwa olumaphakathi, ingaphakamisa umkhawulo wokuquleka, ibangele ukozela nokunye.

Lapho i-pineal gland isusiwe, izilwane zokuhlola zabonisa i-hyperplasia kanye nokwanda kwesisindo sazo zonke izindlala ezibalulwe ngenhla, ikakhulukazi i-gonads ngaphambi kwesikhathi kanye nezitho zobulili zamagundane angavuthiwe, ukwanda kwe-LH ne-FSH ku-pituitary gland, nokwanda kokukhiqizwa kwe-thyroid kanye ne-adrenal. ama-hormone e-cortical.

Isici se-pineal singanciphisa i-pituitary MSH futhi senze isikhumba sibe mhlophe.

Isebenza ohlelweni lwezinzwa olumaphakathi, ikhombisa isigqi esinensayo, ikhulisa umkhawulo wokudlikiza kanye nokukhathala ku-electroencephalogram yomuntu, kodwa ayithinti ukuziphatha kwabo nobuntu. Kunganciphisa izinguquko ze-electroencephalogram zokuphazamiseka kwemizwa yezimoto kubantu abanesifo sokuwa se- temporal lobe nesifo sika-Parkinson.
