Phosphate group resonance
WebIn biochemistry and medicinal chemistry, phosphonate groups are used as stable bioisosteres for phosphate, such as in the antiviral nucleotide analog, Tenofovir, one of the cornerstones of anti-HIV therapy. And there is an indication that phosphonate derivatives are "promising ligands for nuclear medicine." http://guweb2.gonzaga.edu/faculty/cronk/CHEM245pub/phosphoryl.html
Phosphate group resonance

WebSome 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. Functional groups can sometimes be classified as having ... WebThe phosphoanhydride bonds of ATP, or the bonds between phosphate molecules, are high energy. This is due to the close proximity of positively charged phosphate and negatively charged oxygen; these charges repel. Also, there is resonance stabilization of the products of ATP hydrolysis (ADP and Pi); thus ADP is more stable than ATP.
Web3-. (Phosphate ion) Resonance Structures. Resonance structures of PO 43- ion can be drawn by using lewis structure of phosphate ion. four stable resonance structures can be drawn for PO 43- ion. These resonance … WebWhile both resonance structures are chemically identical, the negative charge is on a different oxygen in each. This is important because neither resonance structure actually exists, instead there is a hybrid. The oxygens share the negative charge with each other, stabilizing it, and reducing the charge on either atom. 2 comments.
