Qhov sib txawv tseem ceeb ntawm qabzib 6 phosphate thiab fructose 6 phosphate yog cov piam thaj 6 phosphate muaj phosphate pawg txuas nrog 6 thcarbon atom ntawm cov piam thaj molecule, whereas fructose 6 phosphate muaj ib pawg phosphate txuas nrog 6 th carbon ntawm fructose molecule.
Glucose 6 phosphate thiab fructose 6 phosphate yog cov suab thaj tseem ceeb uas tau dhau los ua phosphorylation los txuas cov phosphate rau hauv cov piam thaj molecules.
Glucose 6 Phosphate yog dab tsi?
Glucose 6 phosphate yog piam thaj qab zib uas yog phosphorylated ntawm pawg hydroxy ntawm carbon 6. Qhov no yog dianion, thiab nws muaj nyob rau hauv cov hlwb vim tias feem ntau ntawm cov piam thaj nkag mus rau hauv lub cell ua phosphorylated ntawm 6th carbon atom. Vim nws txoj haujlwm tseem ceeb hauv cellular chemistry, qhov sib xyaw no muaj ntau txoj hmoo hauv lub cell. Nws kuj zoo li dag thaum pib ntawm ob txoj hauv kev loj hauv metabolic, suav nrog glycolysis thiab txoj hauv kev pentose phosphate. Tsis tas li ntawd, ob txoj hauv kev metabolic no tseem suav nrog kev hloov pauv ntawm qabzib 6 phosphate rau hauv glycogen lossis hmoov txhuv nplej siab rau khaws cia. Kev khaws cia yog ua tiav hauv daim siab thiab cov leeg ua glycogen.
Daim duab 01: Cov Qauv Tshuaj ntawm Glucose 6 Phosphate
Cov tshuaj formula ntawm qabzib 6 phosphate yog C6H13O9P. Nws molar mass yog 260.136 g / mol. Hauv ib lub cell, qabzib 6 phosphate tuaj yeem tsim los ntawm phosphorylation ntawm qabzib ntawm cov pa roj carbon thib rau, uas yog catalyzed los ntawm enzyme hexokinase hauv feem ntau cov hlwb. Hauv cov tsiaj siab dua, glucokinase yog siv hauv qee lub hlwb, xws li lub siab hlwb. Hauv cov tshuaj tiv thaiv no, ib qho sib npaug ntawm ATP tau noj. Qhov phosphorylation tam sim no tshwm sim txhawm rau txhawm rau tiv thaiv kev tawm ntawm cov hlwb. Ntxiv mus, cov txheej txheem no ntxiv ib pawg phosphate them, ua kom yooj yim hla ntawm cov cell membrane.
Thaum cov hlwb xav tau lub zog rau cov pob txha pob txha synthesis, hlwb tsom cov piam thaj 6 phosphate rau glycolysis. Ua ntej, qhov sib xyaw no yog isomerized rau fructose 6 phosphate ntawm phosphor-glucose isomerase. Nws siv magnesium ua cofactor.
Fructose 6 Phosphate yog dab tsi?
Fructose 6 phosphate yog qabzib qab zib uas muaj cov tshuaj formula C6H13O9 P. Nws molar mass yog 260.14 g / mol. Nws yog derivative ntawm fructose. Fructose yog phosphorylated ntawm 6 th hydroxy pawg. Peb tuaj yeem hu nws fructophosphate. Nws muaj ib daim ntawv beta-D uas muaj ntau heev hauv cov hlwb. Tsis tas li ntawd, feem ntau ntawm cov piam thaj hloov mus rau hauv fructose 6 phosphate thaum nkag mus rau hauv lub cell. Feem ntau, fructose hloov mus rau fructose 1 phosphate nyob rau hauv lub xub ntiag ntawm fructokinase.
Daim duab 02: Cov qauv tshuaj ntawm Fructose 6 Phosphate
Nyob rau hauv cov txheej txheem ntawm glycolysis, fructose 6 phosphate nyob hauv glycolysis metabolic txoj kev, thiab nws yog tsim los ntawm isomerization ntawm qabzib 6 phosphate. Ntxiv mus, nws tuaj yeem raug ntxiv phosphorylated rau hauv fructose-1, 6-bisphosphate.
Qhov txawv ntawm Glucose 6 Phosphate thiab Fructose 6 Phosphate yog dab tsi?
Qhov sib txawv tseem ceeb ntawm qabzib 6 phosphate thiab fructose 6 phosphate yog cov piam thaj 6 phosphate muaj phosphate pawg txuas nrog 6 thcarbon atom ntawm cov piam thaj molecule, whereas fructose 6 phosphate muaj ib pab pawg phosphate txuas nrog 6 th carbon ntawm fructose molecule. Tsis tas li ntawd, glucokinase lossis hexokinase IV yog cov enzyme koom nrog hauv kev tsim cov piam thaj 6 phosphate thaum phosphofructokinase yog cov enzyme koom nrog hauv kev tsim cov fructose 6 phosphate.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm qabzib 6 phosphate thiab fructose 6 phosphate hauv daim ntawv tabular rau kev sib piv ntawm ib sab.
Summary – Glucose 6 Phosphate vs Fructose 6 Phosphate
Glucose 6 phosphate thiab fructose 6 phosphate yog ob lub qab zib qab zib uas muaj cov tshuaj formula C6H13O9 P. Qhov sib txawv tseem ceeb ntawm cov piam thaj 6 phosphate thiab fructose 6 phosphate yog cov piam thaj 6 phosphate muaj phosphate pawg txuas nrog 6 thcarbon atom ntawm cov piam thaj molecule, whereas fructose 6 phosphate muaj phosphate pawg. txuas rau 6th carbon ntawm fructose molecule.
