Calcium

Calcium, Ca2+

  • Increases rigidity of bone, teeth and cartilage and is a component of the exoskeleton of crustaceans.
  • Important in clotting blood and muscle contraction.
  • Activator for several enzymes, such as lipase, ATPase and cholinesterase.
  • Stimulates muscle contraction and regulates transmission of nerve impulses.
  • Regulates permeability of cell membranes
  • Important for cell wall development in plant, and formation of middle lamella between cell walls.

Sodium

Sodium, Na+

  • Involved in regulation of osmotic pressure, control of water levels in bofy fluid and maintenance of pH.
