State of Calcium in Body Fluids
- Physical Properties of Calcium
- the concentration of ionic calcium in blood must be kept below solubilityproduct 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
Calcium flux and endogenous calcium content in isolated mammalian growth-plate chondrocytes, hyaline-cartilage chondrocytes, and hepatocytes.
