Qhov sib txawv tseem ceeb ntawm pawg phosphoryl thiab phosphate pawg yog cov phosphoryl pawg muaj ib phosphorus atom khi rau peb cov pa atoms thiab -2 nqi, whereas phosphate pawg muaj ib phosphorous atom khi rau plaub oxygen atoms thiab -3 nqi.
Phosphoryl pawg yog cov tshuaj ion uas muaj cov tshuaj formula P+O32-thaum phosphate pawg yog anion muaj cov tshuaj formula PO4-3.
Phosphoryl Group yog dab tsi?
Phosphoryl pawg yog cov tshuaj ion uas muaj cov tshuaj formula P+O32- Yog li ntawd, cov ion no muaj phosphorous thiab oxygen atoms. Nws tuaj yeem muaj nyob hauv ntau lub xeev protonation. Lub sij hawm no yog siv feem ntau rau cov tshuaj sib txuas uas muaj cov phosphoryl pawg txuas mus rau lwm lub atom, xws li phosphoryl chloride compound, uas muaj phosphoryl pawg txuas nrog chloride anion. Lo lus no kuj tseem siv tau los piav txog cov txheej txheem catalytic xws li phosphorylation.
Daim duab 01: Cov tshuaj formula ntawm Phosphoryl Group thiab Phosphate Group
Thaum xav txog cov txheej txheem biochemical, yog tias pawg phosphate koom nrog cov tshuaj tiv thaiv, ib pawg phosphoryl feem ntau yog pauv ntawm cov substrate compounds. Cov tshuaj tiv thaiv no hu ua phosphoryl hloov cov tshuaj tiv thaiv. Txawm li cas los xij, pawg phosphoryl tsis yog pawg phosphate.
Phosphate Group yog dab tsi?
Ib pawg phosphate yog anion muaj cov tshuaj PO4-3 lo lus no siv tau rau npe am anion, ntsev Cov tshuaj muaj phosphate pawg, ib pab pawg ua haujlwm thiab cov esters uas muaj phosphate pawg. Feem ntau, peb hu qhov no anion yog orthophosphate anion vim nws tsim los ntawm orthophosphoric acid.
Daim duab 02: Cov Qauv Tshuaj ntawm Phosphate Group
Cov anion no tsim los ntawm phosphoric acid los ntawm kev tshem tawm peb cov protons. Kev tshem tawm ntawm ib qho proton ua rau dihydrogen phosphate anion, thaum tshem tawm ntawm ob protons ua hydrogen phosphate anion. Cov npe no tuaj yeem siv los xa mus rau lawv cov ntsev sib txuas.
Cov molar loj ntawm phosphate anion yog 94.97 g / mol. Muaj lub hauv paus phosphorous atom txuas rau plaub lub atoms oxygen, thiab cov anion muaj tetrahedral geometry. Feem ntau ntawm cov phosphate-muaj cov tebchaw yog cov dej-soluble tshuaj nyob rau hauv chav tsev kub thiab siab. Qee cov phosphate compounds kuj insoluble hauv dej.
Hauv cov kab ke lom neeg, peb tuaj yeem pom cov phosphate hauv cov ntawv inorganic phosphate. Peb tuaj yeem nrhiav cov phosphate anions dawb hauv cov kev daws teeb meem hauv cov tshuab lom neeg. Yog tias tsis yog, phosphate anions tshwm sim ua ke rau cov organic molecules hauv daim ntawv ntawm organophosphates. Feem ntau, phosphates tuaj yeem pom ua esters hauv nucleotides, hauv DNA thiab hauv RNA.
Qhov txawv ntawm Phosphoryl Group thiab Phosphate Group yog dab tsi?
Phosphoryl pawg yog cov tshuaj ion uas muaj cov tshuaj formula P+O32-thaum pawg phosphate yog ib qho anion muaj cov tshuaj formula PO4-3 Qhov sib txawv tseem ceeb ntawm pawg phosphoryl thiab phosphate pawg yog cov phosphoryl. pawg muaj ib tug phosphorus atom khi rau peb oxygen atoms thiab -2 nqi, whereas pawg phosphate muaj ib tug phosphorous atom khi rau plaub oxygen atoms thiab -3 nqi.
Daim duab hauv qab no nthuav tawm qhov sib txawv ntawm pawg phosphoryl thiab phosphate pawg hauv daim ntawv.
Summary – Phosphoryl Group vs Phosphate Group
Ib pawg phosphoryl yog tshuaj ion uas muaj cov tshuaj formula P+O32-Meanwhile, pawg phosphate yog ib qho anion uas muaj cov tshuaj formula PO4-3 Qhov sib txawv tseem ceeb ntawm pawg phosphoryl thiab phosphate pawg yog tias phosphoryl pawg muaj ib qho phosphorus atom khi rau peb cov pa atoms thiab -2 nqi, whereas pawg phosphate muaj ib tug phosphorous atom khi rau plaub oxygen atoms thiab -3 nqi.
