  2. Phosphoric acid - Wikipedia

    en.wikipedia.org/wiki/Phosphoric_acid

    Phosphoric acid (orthophosphoric acid, monophosphoric acid or phosphoric (V) acid) is a colorless, odorless phosphorus -containing solid, and inorganic compound with the chemical formula H 3 P O 4. It is commonly encountered as an 85% aqueous solution, which is a colourless, odourless, and non- volatile syrupy liquid.

    en.wikipedia.org/wiki/Phosphoric_acids_and...

    Phosphoric acids and phosphates. Appearance. Pyrophosphoric acid. In chemistry, a phosphoric acid, in the general sense, is a phosphorus oxoacid in which each phosphorus (P) atom is in the oxidation state +5, and is bonded to four oxygen (O) atoms, one of them through a double bond, arranged as the corners of a tetrahedron.

  4. Acid phosphatase - Wikipedia

    en.wikipedia.org/wiki/Acid_phosphatase

    Acid phosphatase. Acid phosphatase (EC 3.1.3.2, systematic name phosphate-monoester phosphohydrolase (acid optimum)) is an enzyme that frees attached phosphoryl groups from other molecules during digestion. It can be further classified as a phosphomonoesterase. It is stored in lysosomes and functions when these fuse with endosomes, which are ...

  5. Organophosphate - Wikipedia

    en.wikipedia.org/wiki/Organophosphate

    Organophosphate. In organic chemistry, organophosphates (also known as phosphate esters, or OPEs) are a class of organophosphorus compounds with the general structure O=P (OR)3, a central phosphate molecule with alkyl or aromatic substituents. [1] They can be considered as esters of phosphoric acid. Organophosphates are best known for their use ...

  6. Phosphate - Wikipedia

    en.wikipedia.org/wiki/Phosphate

    In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid, a.k.a. phosphoric acid H3PO4. The phosphate or orthophosphate ion [PO. 4]3−. is derived from phosphoric acid by the removal of three protons H+.

  7. Phosphorus oxoacid - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_oxoacid

    Phosphorus oxoacid. In chemistry, phosphorus oxoacid (or phosphorus acid) is a generic name for any acid whose molecule consists of atoms of phosphorus, oxygen, and hydrogen. [1] There is a potentially infinite number of such compounds. Some of them are unstable and have not been isolated, but the derived anions and organic groups are present ...

  8. Hypophosphatemia - Wikipedia

    en.wikipedia.org/wiki/Hypophosphatemia

    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.

  9. Ortho acid - Wikipedia

    en.wikipedia.org/wiki/Ortho_acid

    Ortho acid. In organic chemistry, ortho acids are organic, hypothetical chemical compounds having the structure R−C (OH)3 (R = alkyl or aryl). [1] Ortho acids themselves are unstable and cannot be isolated. However, ortho esters can be synthesized by the Pinner reaction, in which nitriles react with alcohols under acid catalysis:
