Inkcazo
I-caffeine yinkqubo ye-nervous central (CNS) ecaphukisayo kwaye iyinxalenye ye-alkaloids. Icaffeine inemisebenzi eyahlukahlukeneyo, efana nokunyusa inqanaba lamandla omzimba, iphucula ubuntununtunu bobuchopho, kunye nokwandisa imincili kwi-neural.
I-caffeine ikhona kwiintlobo ezahlukeneyo zokutya zendalo, njengeti, ikofu, i-guarana, i-cocoa kunye ne-cola. Yeyona stimulant isetyenziswa kakhulu, phantse 90% yabantu abadala American rhoqo usebenzisa caffeine.
I-caffeine inokutsalwa ngokukhawuleza kwi-digestive tract kwaye yenza umphumo wayo ophezulu (ukufikelela kwi-concentration yayo) ngaphakathi kwe-15 ukuya kwi-60 imizuzu emva kokusetyenziswa. Ubomi besiqingatha se-caffeine emzimbeni womntu yi-2.5 kwiiyure ze-4.5.
Umsebenzi ongundoqo
I-caffeine inokuthintela i-adenosine receptors kwingqondo, ikhawuleza i-dopamine kunye ne-cholinergic neurotransmission. Ukongeza, i-caffeine inokuchaphazela i-cyclic adenosine monophosphate kunye ne-prostaglandins.
Kufuneka kuqatshelwe ukuba i-caffeine inefuthe elincinci le-diuretic.
Njengesongezelelo sezemidlalo (isithako), i-caffeine idla ngokusetyenziswa ngaphambi koqeqesho okanye ukhuphiswano. Inokuphucula amandla omzimba, uvakalelo lobuchopho (ukugxila), kunye nolawulo lokucutheka kwemisipha yabadlali okanye abathanda ukuqina, okubavumela ukuba baqeqeshe ngamandla amakhulu kwaye bafumane iziphumo ezingcono zoqeqesho. Kubalulekile ukuqaphela ukuba abantu abahlukeneyo baneendlela ezahlukeneyo zokusabela kwi-caffeine.
