calcium metabolism
-multiple biological functions of calcium
-cell signaling
-neural transmission
-muscle function
-blood coagulation
-enzymatic co-factor
-membrane and cytoskeletal functions
-secretion
-biomineralization
-absorption-duodenum and proximal jejunum.
-active transport across cells.
-calcium-binding proteins (calbindins) are synthesized in response to the action of
-parathyroid hormone - also increased intestinal absorption of
-absorption is inhibited by
