Mikronutrijent

Izvor: Wikipedija

Mikronutrijenti su nutrijenti koji su neohodni tokom života ljudi i drugih živih bića u malim količinama da bi se omogućilo odvijanje niza fizioloških funkcija. Živi organizmi ne mogu sami da proizvedu mikronutrijente.[1] Kod ljudi ova grupa materija obuhvata mikrominerale koji su neophodni manjim od 100 miligrama na dan[2], za razliku od makrominerala, koji su neohodni u većim količinama. U mikrominerale se ubrajaju gvožđe[3], kobalt, hrom, bakar[4][5][6], jod, mangan, selen, cink[3] i molibden. Mikronutrijenti takođe obuhvataju vitamine, koji su organska jedinjenja.[2]
