Manganese: biological information
Manganese compounds are essential to life. They are essential for the action of some enzymes. Soil deficiencies lead to infertility in mammals and to bone malformation in growing chicks.
Levels in humans
|Human abundance by weight||200 ppb by weight|
|Human abundance by atoms||23 atoms relative to C = 1000000|
