Physical Properties of Calcium:
- Discussion:
- the concentration of
ionic calcium in blood must be kept below solubility
product of Ca phosphate salt, & it is also important that additional calcium
is reversibly complexed with plasma proteins;
- total calcium concentration in plasma is approx l0mg/l00 ml, whereas ionized
portion is slightly > 50% of this amount;
- most clinical problems of either hypo- or hypercalcemia are result of continued
net movement of Ca in only one direction between cell membranes and
extracellular fluid;
