Molybdenum: biological information
Molybdenum is a necessary element, apparently for all species. Only very small amounts are required. Molybdenum plays a role in nitrogen fixation, (a process by which the normally unreactive nitrogen gas is turned into other compounds) enzymes, and nitrate reduction enzymes.
Levels in humans
- Human abundance by weight: 100 ppb by weight
- Human abundance by atoms: 7 atoms relative to C = 1000000

You can use this form to calculate how much molybdenum your body contains. Enter your weight in either kilograms or pounds and click the "Calculate" button. You must enter a number, not text! Elements for which there are no data will always give a value of zero for the weight, no matter what you put in the weight box.
Hazards and Risks
Hazards and risks associated with molybdenum:
Molybdenum compounds are encountered relatively rarely by most people. Unless known otherwise, all molybdenum compounds should be regarded as highly toxic and as teratogenic.
