Ste danes zjutraj spili kavo? Del dru\u017eabnega \u017eivljenja znanstvenikov je odmor za kavo na znanstvenih konferencah, laboratorijskih seminarjih in vsak dan v laboratoriju. Toda kava je tudi znanstvena tema. Predvsem zaradi kofeina, stimulansa osrednjega \u017eiv\u010dnega sistema (CNS) in najbolj raz\u0161irjene psihoaktivne droge na svetu.<\/p>\n\n\n\n

Da bi proslavili kavo - ali pa vam svetovali, da se umirite -, si oglejmo, kako deluje kofein.<\/h3>\n\n\n

Najbolj znan vir je kavno zrno, ki je napa\u010dno poimenovanje za seme rastline Coffea. Napitke, ki vsebujejo kofein, zau\u017eijemo za laj\u0161anje ali prepre\u010devanje zaspanosti in izbolj\u0161anje zmogljivosti. Za pripravo teh pija\u010d se kofein pridobiva z namakanjem rastlinskega proizvoda v vodi, kar se imenuje infuzija. Ti napitki, kot so kava, \u010daj in kola, so zelo priljubljeni; leta 2014 je 85% odraslih Ameri\u010danov dnevno zau\u017eilo neko obliko kofeina, v povpre\u010dju 164 mg.<\/p>\n\n\n

Obstaja ve\u010d znanih mehanizmov delovanja, ki pojasnjujejo u\u010dinke stimulacije. Najpomembnej\u0161i je, da reverzibilno blokira delovanje adenozina na njegov receptor in posledi\u010dno prepre\u010duje nastanek zaspanosti, ki jo povzro\u010da adenozin. Prav tako stimulira dolo\u010dene dele avtonomnega \u017eiv\u010dnega sistema.<\/p>\n\n\n
