26.3: The “High-Energy” Character of Phosphoanhydride Bonds
网页When two phosphate groups are linked to each other, the linkage is referred to as a 'phosphate anhydride', and the ion is called 'inorganic pyrophosphate' (abbreviation PP i). When a phosphate ion is attached to a carbon atom on an organic molecule, the chemical linkage is referred to as a phosphate ester, and the whole species is called an ...
9.2: Overview of Phosphate Groups - Chemistry LibreTexts
网页2022年7月20日 · The fully deprotonated conjugate base of phosphoric acid is called a phosphate ion, or inorganic phosphate (often abbreviated '\(P_i\)'). When two phosphate groups are linked to each other, the linkage itself is referred to as a 'phosphate anhydride', and the compound is called 'inorganic pyrophosphate' (often abbreviated \(PP_i\)).
High-energy phosphate - Wikipedia
网页High-energy phosphate bonds are usually pyrophosphate bonds, acid anhydride linkages formed by taking phosphoric acid derivatives and dehydrating them. As a consequence, the hydrolysis of these bonds is exergonic under physiological …
Phosphate esters and anhydrides - RSC Publishing
网页Phosphate esters and anhydrides are present in important biomolecules, such as DNA, RNA, nucleotides, nucleoside diphosphate sugars, dinucleoside polyphosphates, inorganic polyphosphate, vitamins, inositol poly- and pyrophosphates, phospholipids, various metabolites and proteins.

网页The fully deprotonated conjugate base of phosphoric acid is called a phosphate ion, or inorganic phosphate (often abbreviated ‘P* i ’). When two phosphate groups are linked to each other, the linkage itself is referred to as a ‘phosphate anhydride’, and the compound is called ‘inorganic pyrophosphate’ (often abbreviated PP i *). fig 1
Why Nature Chose Phosphates | Science - AAAS
网页Phosphate esters and anhydrides dominate the living world but are seldom used as intermediates by organic chemists. Phosphoric acid is specially adapted for its role in nucleic acids because it can link two nucleotides and still ionize; the resulting negative charge serves both to stabilize the diesters against hydrolysis and to retain the ...

Why nature chose phosphate to modify proteins - PMC
网页2012年9月9日 · Phosphate esters are readily formed under physiological conditions using adenosine triphosphate (ATP), a phosphate anhydride, as a phosphate donor and an enzyme catalyst. Once formed, phosphate esters are chemically stable in aqueous solution at physiological pH, and yet they are easily hydrolysed by an …
