1.6: Functional Groups - Chemistry LibreTexts
Phosphate and its derivative functional groups are ubiquitous in biomolecules. Phosphate linked to a single organic group is called a phosphate ester; when it has two links to organic groups it is called a phosphate diester. A linkage between two phosphates creates a phosphate anhydride.
9.2: Overview of Phosphate Groups - Chemistry LibreTexts
2022年7月20日 · 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 \(PP_i\)). The chemical linkage between phosphate and a carbon atom is a phosphate ester.
3.1: Functional Groups - Chemistry LibreTexts
2023年10月31日 · Many biological organic molecules contain phosphate, diphosphate, and triphosphate groups, which are linked to a carbon atom by the phosphate ester functionality. Because phosphates are so abundant in biological organic chemistry, it is convenient to depict them with the abbreviation 'P'.
In biology magnesium-diphosphophate is the most common leaving group. In acid-hydrolysis of trimethyl phosphate, C-O bond cleavage competes with P-O bond cleavage because phosphates are good leaving groups and it is difficult to attack a phosphate. Phosphites hydrolyze much faster than phosphates. phosphite ..
1.9: Functional Groups - Biology LibreTexts
Some of the important functional groups in biological molecules are shown above; they include: hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and sulfhydryl (R-S-H). These groups play an important role in the formation of molecules like DNA, proteins, carbohydrates, and lipids.

3.4: Functional Groups - Biology LibreTexts
Many biologically active molecules contain one or more functional groups. In BIS2A, we will review the major functional groups found in biological molecules. These include the following: hydroxyl, methyl, carbonyl, carboxyl, amino, and phosphate (see Figure 1).
Natural Products Containing ‘Rare’ Organophosphorus Functional Groups
2019年2月28日 · While the phosphate functional group is very common in small molecule natural products, nucleic acids, and as chemical modification in protein and peptides, phosphorous can form P–N (phosphoramidate), P–S (phosphorothioate), and P–C (e.g., phosphonate and phosphinate) linkages.

2017年1月2日 · Phosphate forms phosphoesters with the hydroxyl groups of a variety of biomolecules of all sizes, notably sugars (for example, glucose 6-phosphate, a phosphate ester of the 6-hydroxyl group of glucose) and proteins .
Phosphates Functional Group - Chemistry Stack Exchange
2016年4月24日 · In my text book it states that a phosphate group is considered to be −OPOX3X2− − O P O X 3 X 2 −. However, online it states that phosphate is POX4X3− P O X 4 X 3 −. Why do these contradict? Am i confusing phosphate the chemical with the phosphate group? Please see image for reference.
