2. Calcium metabolism - Wikipedia

   en.wikipedia.org/wiki/Calcium_metabolism

   Calcium regulation in the human body. [6]The plasma ionized calcium concentration is regulated within narrow limits (1.3–1.5 mmol/L). This is achieved by both the parafollicular cells of the thyroid gland, and the parathyroid glands constantly sensing (i.e. measuring) the concentration of calcium ions in the blood flowing through them.

3. Calcification - Wikipedia

   en.wikipedia.org/wiki/Calcification

   Calcification of soft tissue (arteries, cartilage, heart valves, [1] [2] etc.) can be caused by vitamin K 2 deficiency or by poor calcium absorption due to a high calcium/vitamin D ratio. This can occur with or without a mineral imbalance. A common misconception is that calcification is caused by excess amount of calcium in diet. Dietary ...

4. Calcium in biology - Wikipedia

   en.wikipedia.org/wiki/Calcium_in_biology

   The U.S. Institute of Medicine (IOM) established Recommended Dietary Allowances (RDAs) for calcium in 1997 and updated those values in 2011. [6] See table. The European Food Safety Authority (EFSA) uses the term Population Reference Intake (PRIs) instead of RDAs and sets slightly different numbers: ages 4–10 800 mg, ages 11–17 1150 mg, ages 18–24 1000 mg, and >25 years 950 mg.

5. Calcium - Wikipedia

   en.wikipedia.org/wiki/Calcium

   Calcium is the most abundant metal and the fifth-most abundant element in the human body. [8] As electrolytes , calcium ions (Ca 2+ ) play a vital role in the physiological and biochemical processes of organisms and cells : in signal transduction pathways where they act as a second messenger ; in neurotransmitter release from neurons ; in ...

6. Calcium-binding protein - Wikipedia

   en.wikipedia.org/wiki/Calcium-binding_protein

   The most ubiquitous Ca 2+-sensing protein, found in all eukaryotic organisms including yeasts, is calmodulin. Intracellular storage and release of Ca 2+ from the sarcoplasmic reticulum is associated with the high-capacity, low-affinity calcium-binding protein calsequestrin. [3] Calretinin is another type of Calcium binding protein weighing 29kD ...
