Calcium heeft in het lichaam een rol in botmineralisatie (botopbouw), bloedstolling, plasmamembraanpotentiaal, spiercontractie, hormoonafgifte, glycogeenmetabolisme en celdeling. Calcium bevindt zich in het skelet (99%), in de weefsels en in de extracellulaire vloeistoffen (onder andere het bloed). Een calciumtekort kan leiden tot botontkalking (osteoporose) en bij kinderen tot verschijnselen van rachitis (Engelse ziekte) en spierkrampen. Web15 sep. 2016 · Abstract.
