Calcium phosphates are white solids of nutritional value [2] and are found in many living organisms, e.g., bone mineral and tooth enamel. [3] In milk, it exists in a colloidal form in micelles bound to casein protein with magnesium, zinc, and citrate –collectively referred to as colloidal calcium phosphate (CCP). [4]
PubMed search. [3] [4] Wikidata. View/Edit Human. View/Edit Mouse. Parathyroid hormone (PTH), also called parathormone or parathyrin, is a peptide hormone secreted by the parathyroid glands that regulates the serum calcium concentration through its effects on bone, kidney, and intestine. [5] PTH influences bone remodeling, which is an ongoing ...
Vitamin D is a group of fat-soluble secosteroids responsible for increasing intestinal absorption of calcium, magnesium, and phosphate, along with numerous other biological functions. [ 1 ][ 2 ] In humans, the most significant compounds within this group are vitamin D 3 (cholecalciferol) and vitamin D 2 (ergocalciferol). [ 2 ][ 3 ]
Calcium metabolism is the movement and regulation of calcium ions (Ca 2+) in (via the gut) and out (via the gut and kidneys) of the body, and between body compartments: the blood plasma, the extracellular and intracellular fluids, and bone. Bone acts as a calcium storage center for deposits and withdrawals as needed by the blood via continual ...
Infobox references. Tricalcium phosphate (sometimes abbreviated TCP), more commonly known as Calcium phosphate, is a calcium salt of phosphoric acid with the chemical formula Ca 3 (PO 4) 2. It is also known as tribasic calcium phosphate and bone phosphate of lime (BPL). It is a white solid of low solubility.
Bone resorption is resorption of bone tissue, that is, the process by which osteoclasts break down the tissue in bones [1] and release the minerals, resulting in a transfer of calcium from bone tissue to the blood. [2] The osteoclasts are multi-nucleated cells that contain numerous mitochondria and lysosomes. These are the cells responsible for ...
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.

Frequency. 2% (people in hospital) [1] Hypophosphatemia is an electrolyte disorder in which there is a low level of phosphate in the blood. [1] Symptoms may include weakness, trouble breathing, and loss of appetite. [1] Complications may include seizures, coma, rhabdomyolysis, or softening of the bones.
