Calcium is the most abundant mineral in the human body. [3] The average adult body contains in total approximately 1 kg, 99% in the skeleton in the form of calcium phosphate salts. [3] The extracellular fluid (ECF) contains approximately 22 mmol, of which about 9 mmol is in the plasma. [4]
An increase in serum phosphate (increased phosphate causes it to complex with serum calcium, forming calcium phosphate, which reduces stimulation of Ca-sensitive receptors (CaSr) that do not sense calcium phosphate, triggering an increase in PTH). Adrenaline; Histamine
Non-calcium-based phosphate binders, including lanthanum carbonate, form insoluble complexes with phosphates in food, thereby reducing the amount of phosphate in the body. [1] Sevelamer carbonate. Sevelamer is an insoluble polymeric amine, which is protonated once in the intestines and this allows it to bind dietary phosphate.
Phosphates bind calcium and magnesium ions to prevent 'hard-water' type limescale deposits. They can cause ecological damage, so their use is starting to be phased out. Phosphate-free detergents are sold as eco-friendly detergents.
Diagnosis is generally based on a blood phosphate level exceeding 1.46 mmol/L (4.5 mg/dL). [1] Levels may appear falsely elevated with high blood lipid levels, high blood protein levels, or high blood bilirubin levels. [1] Treatment may include a phosphate low diet and antacids like calcium carbonate that bind phosphate. [1]
Calcium signaling is the use of calcium ions (Ca 2+) to communicate and drive intracellular processes often as a step in signal transduction. Ca 2+ is important for cellular signaling . Once it enters the cytosol of the cytoplasm it exerts allosteric regulatory effects on many enzymes and proteins .
For instance, Ca 2+ (mostly calcium phosphate and some calcium sulfate) is the most important (and specific) element of bone and calcified cartilage. In humans, the total body content of calcium is present mostly in the form of bone mineral (roughly 99%). In this state, it is largely unavailable for exchange/bioavailability.
Calcium-binding proteins can be either intracellular and extracellular. Those that are intracellular can contain or lack a structural EF-hand domain. Extracellular calcium-binding proteins are classified into six groups. [2] Since Ca (2+) is an important second messenger, it can act as an activator or inhibitor in gene transcription.
