Calcium in the Body

The calcium in the body fluids can exist in three forms: (1) as the free ion Ca 2+ (about 50% of the calcium in the fluids), (2) bound to proteins (about 40% of the calcium in the fluids), and (3) complexed with other ions (about 10% of the calcium in the fluids). Of these three, the free ion is the most important for the physiological
