英文字典中文字典相关资料:


  • nomenclature - What is the difference between a phosphoryl group and a . . .
    However, “phosphoryl” is retained in derived terms such as the names of enzymes (e g , phosphorylase) or of processes (e g , phosphorylation) Table I (I won't reproduce it for technical reasons), lists many examples of (1) phosphate names, (2) O -phospho phospho names, (3) systematic names (the first two types marked as recommended for
  • Does protein phosphorylation add a phosphate group, or does it add a . . .
    There is no question that the difference is a phosphoryl group Not a phosphate group I’ll use the general term phosphus compound to refer to something that may be a phosphate group and may be a phosphoryl group
  • biochemistry - Does the phosphorylation of glucose to glucose 6 . . .
    “Phosphoryl groups are essential components in the enzymic conservation of metabolic energy Energy made available with the transfer of phosphoryl groups form compounds with phosphoanhydride bonds (such as those in ATP) is partially conserved in the formation of phosphate esters such as glucose 6-phosphate ”
  • How is phosphoryl chloride attaching an aldehyde to benzene?
    This reaction was part of an organic scheme I was doing: I thought that $\\ce{POCl3}$ just converts the OH group into Cl, but looking at the chemical formula for A, I noticed that A has an extra car
  • organic chemistry - Phosphoryl bromide reaction with benzoic acid . . .
    Well actually @Waylander and @Nilay Ghosh are both correct in a way To convert carboxylic acids into acyl chloride, $\ce{PCl5}$ is often used as a chlorinating agent , which yields an acyl chloride and $\ce{POCl3}$ (and $\ce{HCl}$) as a by-product
  • Why there is no P−O−Cl bond in phosphoryl chloride?
    Phosphorus has the lowest ionisation energy, and thus, it should be in the centre When constructing Lewis structures, the atom with the lowest ionisation energy must be in the middle since it can form the most bonds with other elements, as a lower ionisation energy allows it to form bonds (gain or lose electrons) more readily
  • Why does acetyl have negative charge? - Chemistry Stack Exchange
    "Acetylation (adding an acetyl group) and phosphorylation (adding a phosphate group) make the histones more negatively charged because acetyl and phosphoryl groups are negative They are "glass is half empty" molecules
  • Structure of pyrophosphorous acid - Chemistry Stack Exchange
    As you can see that the textbook has not considered the P-O-P and thus has one less oxygen Just remember that in any oxo acid if the number of oxygen is one more than twice the number of phosphorous sulphur (like in the case above where the number of O=(2*P or S)+1), then it has a bridge bond and if two more than twice the number of phosphorous sulphur (O=(2*P or S)+2) then it has a peroxide
  • Why is DNA negatively charged and what makes it so?
    What part in the strand contributes to the overall non neutral charge? DNA is not isolated in the body, so what keeps it stable while being charged? Why is it important for DNA to be charged?
