Har du drukket kaffe her til morgen? En del af en forskers sociale liv foreg\u00e5r i kaffepausen p\u00e5 videnskabelige konferencer, laboratorieseminarer og i det daglige arbejde i laboratoriet. Men kaffe er ogs\u00e5 et videnskabeligt emne. Hovedsageligt p\u00e5 grund af koffein, som stimulerer centralnervesystemet (CNS) og er verdens mest udbredte psykoaktive stof.<\/p>\n\n\n\n

S\u00e5 for at fejre kaffen - eller for at r\u00e5de dig til at tage den med ro - s\u00e5 lad os se p\u00e5, hvordan koffein virker.<\/h3>\n\n\n

Den mest kendte kilde er kaffeb\u00f8nnen, som er en forkert betegnelse for fr\u00f8et fra Coffea-planten. Drikkevarer, der indeholder koffein, indtages for at lindre eller forhindre d\u00f8sighed og for at forbedre pr\u00e6stationsevnen. For at fremstille disse drikke udvinder man koffein ved at tr\u00e6kke planteproduktet i vand, en proces, der kaldes infusion. Disse drikke, s\u00e5som kaffe, te og cola, er meget popul\u00e6re; i 2014 indtog 85% af voksne amerikanere en eller anden form for koffein dagligt, og de indtog i gennemsnit 164 mg.<\/p>\n\n\n

Der er flere kendte virkningsmekanismer, der forklarer stimuleringens effekter. Den mest fremtr\u00e6dende er, at det reversibelt blokerer adenosins virkning p\u00e5 dets receptor og derfor forhindrer d\u00f8sighed fremkaldt af adenosin. Det stimulerer ogs\u00e5 visse dele af det autonome nervesystem.<\/p>\n\n\n
