Does protein phosphorylation add a phosphate group, or does it add a . . . It’s Adenosine + three phosphoryl groups Phosphorylation involves the transfer of a phosphoryl group and not a phosphate group And we know this because the thing that is transferred has three oxygens, not four oxygens Why then is it called triphosphate?
Why there is no P−O−Cl bond in phosphoryl chloride? There are two main reasons: The bond energy of $\ce {P=O}$ is very high as compared $\ce {P-O}$ and $\ce {O-Cl}$ combined {The bond energy of $\ce {P=O}$ is driving force in many organic reactions -See Reference below} There is high Lone pair repulsions between O and Cl
biochemistry - Does the phosphorylation of glucose to glucose 6 . . . This is an added benefit to the fact that phosphoryl esters can be cleaved to regenerate ADP—especially important when considering each molecule of glucose provides two of 1,3-BPG and eventually PEP, leading to net ATP gain for the whole process
Which are the radicals containing phosphorus in ATP? The ATP molecule contains 3 $\\ce P$ atoms linked through esteric bonds The IUPAC name of triphosphate adenosine is quot;[[(2R,3S,4R,5R)-5-(6-aminopurin-9-yl)-3,4-dihydroxyoxolan-2-yl]methoxy-
Carboxylic acid with Phosphoric acid - Chemistry Stack Exchange The reagent used is usually polyphosphoric acid, a mixture of phosphoric acid and phopshorus pentoxide which is a dehydrating agent This dehydrates the carboxylic acid, giving R-CO+ which does an electrophilic attack on the aromatic ring
Reaction of carboxylic acid with phosphorus trichloride The reaction of carboxylic acid $\ce {RCOOH}$ with $\ce {PCl5}$ $\ce {SOCl2}$ $\ce {PCl3}$ yields an acyl chloride $\ce {RCOCl}$ With $\ce {PCl5}$ and $\ce {SOCl2}$ the reaction is quite simple utilizing one mole reactants and yielding products But in case of $\ce {PCl3}$ the balanced reaction is as follows: $$\ce {3RCOOH + PCl3 -> 3RCOCl + H3PO3}$$ First I thought the reaction would
