Dissolved in water
- Absorbed small intestine
More than one oxidation state
-
Interaction between minerals
-Minerals with similar orbitais and coordination numbers antagonize each other directly by competing for the same binding site
-Copper influences the mobilization of iron from the liver
Interaction with fibers
-Dietary intake(25-30g/day)_Decrease the absorption of Ca or Mg
-Bound to phytate ,oxalate&tannin in salt forms
Interaction with vitamins
-vitamin D enhance the absorption of calcium
-vitamin C enhance the absorption of Iron
Either enhance or decrease the toxicity potential of another mineral
-Occur in food , at a transport ligand, or at ( or within) the intestinal call, blood, lymph, or tissues
