Calcium (Ca 2+) is often considered part of the BMP, [9] [10] though, by definition, it is not part of the CHEM-7. A basic metabolic panel including calcium is sometimes colloquially referred to as a "CHEM-8". Calcium, as an alkaline earth metal, is also an electrolyte, but abnormalities are more commonly associated with malnutrition ...
Bone mineral is composed mainly of calcium, which functions in skeletal mineralization during growth. [4] Puppies younger than 5 months are not able to adjust the absorption of calcium in response to intake, therefore an oversupply or undersupply can be harmful. [10] When raised on diets deficient in calcium, pathological bone fractures can ...
Free calconcarboxylic acid is blue colour, but changes to pink/red when it forms a complex with calcium ions. EDTA forms a more stable complex with calcium than calconcarboxylic acid does, so addition of EDTA to the Ca–calconcarboxylic acid complex causes formation of Ca-EDTA instead, leading to reversion to the blue colour of free ...
[7] The ratio of calcium to phosphorus is essential to bone and teeth health; if there is excessive phosphorus within a diet, it can result in resorption and reduction of the alveolar bone [7] as shown in Henrikson's studies when dogs were fed a low calcium, high phosphorus diet. [8]
The plasma total calcium concentration is in the range of 2.2–2.6 mmol/L (9–10.5 mg/dL), and the normal ionized calcium is 1.3–1.5 mmol/L (4.5–5.6 mg/dL). [4] The amount of total calcium in the blood varies with the level of plasma albumin, the most abundant protein in plasma, and therefore the main carrier of protein-bound calcium in the blood.
The US 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.

Increased dietary magnesium and phosphorus decreases the amount of calcium in the urine, and increased dietary calcium reduces absorption of oxalates from the intestines. [10] Potassium citrate has been recommended to prevent calcium oxalate stone formation because it forms a soluble complex with oxalates and promotes the formation of alkaline ...
A Piper diagram is a graphical representation of the chemistry of a water sample or samples. The cations and anions are shown by separate ternary plots. The apexes of the cation plot are calcium, magnesium and sodium plus potassium cations. The apexes of the anion plot are sulfate, chloride and carbonate plus hydrogen carbonate anions.
