Molybdæn (Mo)

Molybdæn er et sporstof. En voksen indeholder 8-10 mg, som fortrinsvis findes i lever, nyrer, binyrer, milt, knogler, tænder og hud. Molybdæn er indbygget i B12 vitaminet og i en række enzymer, som regulerer omsætningen af næringsstoffer.

Funktioner og betydning for

Mangler og dårlig udnyttelse forårsages af

Mangelsymptomer

Forekommer tilsyneladende meget sjældent, da kosten indeholder rigelig. Men måske som følge af langvarig, kunstig ernæring.

Kilder

Især gule ærter, hvidløg, rød peberfrugt, linser, kornprodukter, nødder, æg og mejeriprodukter. Desuden anden frugt og grønt.

Gule ærter og hvidløg 70
Tørrede linser 69
Grønne bønner 20
Havregryn 10
Mælk, kylling 5

Anbefalet daglig tilførsel

Behovet er ikke fastsat. På grund af uvisheden ligger anbefalingerne på mængder, som svarer til den danske gennemsnitskost
Voksne 11 år og opefter: 50 mikrogram
Børn 1-10 år: 17 mikrogram

Øget behov

Kendes ikke

Overdosering – bivirkninger

Forekommer normalt ikke gennem kosten. Men ved daglig indtagelse på 500-600 mikrogram og derover, kan der optræde symptomer på forgiftning.

Vigtigt at vide

Molybdæn og kobber modarbejder hinanden (antagonister). Molybdæn er et tungmetal, der også anvendes i industrien, men det er tilsyneladende ret ugiftigt i denne sammenhæng.
