Chemical Structure of Vitamins and Minerals

Dietary minerals may be present in inorganic salts, or as part of carbon-containing organic compounds. For example, magnesium is present in chlorophyll, the pigment that makes plants green. Six minerals are required by people in gram amounts: sodium (Na), potassium (K), calcium (Ca), magnesium (Mg), phosphorus (P), and chlorine (Cl).
