Product description:
Calcium plays an active physiological role in bone mineralisation, neuromuscular excitability,
muscle contraction, and blood coagulation. Many enzymes require calcium ions as a cofactor,
including several of the factors. Plasma calcium levels in mammals are tightly regulated, with
bone acting as the major mineral storage site. Intracellular calcium is stored in the
mitochondria and the endoplasmic reticulum. Calcium ions (Ca2+)), are released from bone into
the bloodstream under controlled conditions and is transported as dissolved ions or
protein-bound.
Approximately 50% of the calcium is free and 40 to 45% is protein bound and is mainly associated
with albumin. Remaining 5 to 10% is found in complexes. Calcaemia measures total calcium but
only free calcium is biologically active.
