  2. Phosphoric acids and phosphates - Wikipedia

    en.wikipedia.org/.../Phosphoric_acids_and_phosphates

    Since orthophosphoric acid has three −OH groups, it can esterify with one, two, or three alcohol molecules to form a mono-, di-, or triester. See the general structure image of an ortho- (or mono-) phosphate ester below on the left, where any of the R groups can be a hydrogen or an organic radical. Di- and tripoly- (or tri-) phosphate esters ...

  3. 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 H 3 PO 4. The phosphate or orthophosphate ion [PO 4] 3− is derived from phosphoric acid by the removal of three protons H +.

  4. Phosphorylation - Wikipedia

    en.wikipedia.org/wiki/Phosphorylation

    Serine in an amino acid chain, before and after phosphorylation. In biochemistry, phosphorylation is the attachment of a phosphate group to a molecule or an ion. [1] This process and its inverse, dephosphorylation, are common in biology. [2] Protein phosphorylation often activates (or deactivates) many enzymes. [3] [4]

  5. Organophosphate - Wikipedia

    en.wikipedia.org/wiki/Organophosphate

    Phosphate esters bearing P-OH groups are acidic. The pKa of the first OH group is typically between 1-2, while the second OH deprotonates at a pKa between 6-7. [21] As such, phosphate mono- and di-esters are negatively charged at physiological pH. [22]

  6. Protein phosphorylation - Wikipedia

    en.wikipedia.org/wiki/Protein_phosphorylation

    Model of a phosphorylated serine residue Serine in an amino acid chain, before and after phosphorylation.. Protein phosphorylation is a reversible post-translational modification of proteins in which an amino acid residue is phosphorylated by a protein kinase by the addition of a covalently bound phosphate group.

  7. 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. It is a major industrial ...

  8. Nucleic acid - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid

    The term nucleic acid is the overall name for DNA and RNA, members of a family of biopolymers, [13] and is a type of polynucleotide. Nucleic acids were named for their initial discovery within the nucleus, and for the presence of phosphate groups (related to phosphoric acid). [14]

  9. Phosphorus oxoacid - Wikipedia

    en.wikipedia.org/wiki/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.
