Descripción

Application

Calcium carbonate has been utilized by plants and animal for the formation of their skeletons and shells. It also facilitates the calcium carbonate crystal growth on a chitosan substrate.

Biochem/physiol Actions

Calcium carbonate is a naturally occurring compound that reduces T4 absorption and enhancess serum thyrotropin levels. It also precludes osteoporosis induced by thyrotropin-suppressive doses of levothyroxine in postmenopausal women. Additionally, it reduces diarrhea in individuals with protease inhibitor-induced HIV-infection.
