Incazelo
I-caffeine iyisistimu yezinzwa ephakathi (CNS) ecasulayo futhi iyingxenye ye-alkaloids. I-caffeine inemisebenzi eyahlukene, njengokwandisa izinga lamandla omzimba, ithuthukisa ukuzwela kobuchopho, nokwandisa ukuthakasela kwemizwa.
I-caffeine ikhona ekudleni okungokwemvelo okuhlukahlukene, njengetiye, ikhofi, i-guarana, i-cocoa, ne-cola. Yisikhuthazi esisetshenziswa kakhulu, cishe i-90% yabantu abadala baseMelika abasebenzisa i-caffeine njalo.
I-caffeine ingamuncwa ngokushesha umgudu wokugaya ukudla futhi ibe nomphumela wayo omkhulu (ifinyelele ukugcwala kwayo okuphezulu) phakathi kwemizuzu eyi-15 kuya kwengama-60 ngemuva kokusetshenziswa. Ingxenye yempilo ye-caffeine emzimbeni womuntu ingamahora angama-2.5 kuye kwangama-4.5.
Umsebenzi Oyinhloko
I-caffeine ingavimbela ama-adenosine receptors ebuchosheni, isheshise i-dopamine kanye ne-cholinergic neurotransmission. Ngaphezu kwalokho, i-caffeine ingaphinde ithinte i-cyclic adenosine monophosphate ne-prostaglandins.
Kufanele kuqashelwe ukuthi i-caffeine inomphumela omncane we-diuretic.
Njengesengezo sezemidlalo (isithako), i-caffeine ivame ukusetshenziswa ngaphambi kokuqeqeshwa noma ukuncintisana. Ingathuthukisa amandla omzimba, ukuzwela kobuchopho (ukugxilisa ingqondo), nokulawula ukufinyela kwemisipha yabasubathi noma abathanda ukufaneleka, okubavumela ukuthi baziqeqeshe ngomfutho omkhulu futhi bathole imiphumela engcono yokuqeqeshwa. Kuyaphawuleka ukuthi abantu abahlukene banendlela ehlukile yokusabela nge-caffeine.
