2016年11月29日 · A process (catalysed by enzymes) involving the transfer of a phosphate group from a donor to a suitable acceptor; in general, an ester linkage is formed (…) See, not ‘phosphoryl’, but ‘phosphate’ group. Phosphoryl is very different group. Cite from IUPAC Nomenclature of organic chemistry, preferred names (2013):

2016年1月28日 · I would like to ask whether or not the "Phosphate Functional Group" itself is acidic. I understand that the compound Phosphoric Acid is very acidic, with several hydrogens. However the Phopshate itself lacks hydrogens to donate. Please clear up any misudnerstandings I am having right now. Thank you so much.

2021年12月12日 · Is a phosphate group transferred.from the ATP , or is a phosphoryl group transferred from the ATP. And also, you have to know the difference between a phosphate group and a phosphoryl group. A phosphoryl group has three oxygens.

2016年4月24日 · The phosphate has donated one pair of electrons on the oxygen to have a covalent bond with other molecule, for instance sugar in the image, and becomes a phosphate group in the molecule. Since the electron pair does not sit on the oxygen any more, but is shared with carbon, the phosphate charge is lowered to −2.

2018年6月15日 · Given the neutral phosphate group with both hydroxyl hydrogens attached, either one has an equal probability of being removed as a proton, corresponding to the lower of the two $\mathrm{p}K_\mathrm{a}$ values. The drawing simply picked one …

The reason why DNA is negatively charged is the phosphate group that makes up every nucleotide (pentose + nitrogenous base + phosphate). When forming part of the phosphodiester bond, they retain 1 of 2 negative charges (the other being lost to form the other ester bond to a new pentose, that's why the bond is called "phospho-di-ester").

Very observant! What happens is that phosphorus is hybridized in the phosphate ion. Hybridization allows the central phosphate atom to form more bonds than you might expect from its ground state electron configuration. Within the framework of hybridization, one may look at the bonds in the phosphate anion as having a great deal of ionic character.

2015年12月14日 · A poly-atomic ion is a group of atoms that act as a single ion, it has no bearing on the bonding with-in the molecule. The oxygen-phosphorous bonds are covalent but polar, the molecule its-self is charged, but lacks a direction across the molecule of the charge making phosphate non-polar.

2020年9月6日 · A video I watched showed the construction of a phosphate group using a Lewis structure. The oxygen with the double bond fills its octet group. The three other oxygens lack an electron. The teacher merely pointed out this lack and added the missing electrons (shown in red). Where do these missing electrons come from?

2020年9月9日 · In dehydration synthesis of nucleotides, the hydrogen atom from the 3' carbon on the deoxyribose sugar of one nucleotide reacts with the hydroxyl group on the phosphate group of another nucleotide to form water. As the water molecule forms, a new covalent bond comes into existence between the two nucleotides.
