Functions: carry an electrical charge & attract h2o. 2 categories: macro/major minerals: daily intake of at least 100mg, micro/trace minerals: daily intake of less than 100mg. Help maintain hydration & muscle function: blood fortifiers. Involved in the maintenance of bone structure & function. ~1. 4kg if calcium in the body: 99% is in bones & teeth; 1% distributed in intra & extracellular fluids. 1% plays an important role in determining how much of the 99% stays in the bone. Functions: structural component of bones & teeth, maintenance of acid-base balance, critical role in muscle contraction, transmission of nerve impulses, blood clotting, & cofactor for enzyme activation. Digestion/absorption: 25-30% of ingested ca2+ is absorbed.
