Ib pawg phosphate tsuas yog ib qho phosphorus atom khi rau plaub cov pa atoms, tab sis nws muaj ntau lub luag haujlwm tseem ceeb. Ua ke nrog cov suab thaj thiab cov hauv paus, nws ua rau cov kua qaub nucleic, zoo li DNA thiab RNA.

Ntawm no, vim li cas phosphorus tseem ceeb hauv DNA?

Rau starters, phosphorus yog ib tseem ceeb yam ntxwv yam nyob rau hauv DNA thiab RNA. Ob leeg ntawm cov noob caj noob ces muaj qab zib-phosphate qaum. Phosphate plays lwm lub luag hauj lwm nyob rau hauv lub cell ib yam li ntawd nyob rau hauv DNA . Nws qhia txog peb zaug hauv adenosine triphosphate, lossis ATP, uas yog daim ntawv tseem ceeb ntawm kev khaws cia hluav taws xob hauv cov cell.

Ib sab saum toj no, phosphate muaj nuj nqi yog dab tsi? Phosphate yog lub tsub nqi (ion) uas muaj cov ntxhia phosphorus. Lub cev xav tau phosphorus los txhim kho thiab kho cov pob txha thiab cov hniav, pab kom qab haus huv muaj nuj nqi , thiab makemuscles cog lus. Qhov seem ntawm nws yog khaws cia rau hauv cov ntaub so ntswg thoob plaws lub cev. Lub raum pab tswj tus nqi ntawm phosphate hauv cov ntshav.

Ib tus kuj yuav nug, vim li cas phosphorus thiaj li tseem ceeb?

Lub luag haujlwm tseem ceeb ntawm phosphorus yog nyob rau hauv kev hloov pauv ntawm cov pob txha thiab cov hniav. Nws ua si ib qho tseem ceeb Lub luag haujlwm ntawm lub cev siv cov carbohydrates thiab cov rog li cas. Nws kuj tseem xav tau rau lub cev los ua cov protein rau kev loj hlob, kev saib xyuas, thiab kho cov hlwb thiab cov ntaub so ntswg.

Muaj pes tsawg phosphates muaj DNA?

Ib qho dawb, tsis koom nrog nucleotide feem ntau muaj nyob hauv daim ntawv atriphosphate; uas yog, nws muaj cov saw ntawm peb phosphates . Hauv DNA txawm li cas los xij, nws poob ob yam no phosphate pab pawg, kom tsuas yog ib phosphate isincorporated rau hauv ib txoj hlua ntawm DNA.
