Lub luag hauj lwm lom ntawm phosphorus thiab nitrogen hauv lub cev

Tej yam kab mob, pib cov kab mob me me thiab xaus nrog cov tsiaj txhu, muaj cov tshuaj chem. Hauv peb lub cev, koj tuaj yeem pom tias yuav luag txhua lub sijhawm, uas qhia tias qhov tseem ceeb ntawm ntau yam tshuaj. Ntawm no peb yuav tham txog qhov tseem ceeb ntawm phosphorus thiab nitrogen.

Lub luag hauj lwm lom ntawm phosphorus thiab nws cov sib txuas

Tag nrho cov kev ua si yog ib qho tseem ceeb ntawm kev tswj lub cev hauv lub cev homeostasis. Tib yam mus rau phosphorus, uas tsis yog lub luag haujlwm kawg. Lub luag hauj lwm lom ntawm phosphorus thiab qhov twg nws tshwm sim feem ntau yog dab tsi?

Nyob rau hauv lub qhov, phosphorus yog pom xwb nyob rau hauv daim ntawv ntawm cov tebchaw. Lub caij niaj hnub ntawm lub caij yog 1600 mg rau ib tus neeg nruab nrab. Phosphorus yog ib feem ntawm cov tshuaj xws li ATP (adenosine triphosphate), nucleic acids (DNA thiab RNA), phospholipids ntawm daim nyias nyias.

Lub luag hauj lwm lom ntawm phosphorus hauv lub cev yog txuam nrog kev tswj tus qauv ntawm cov pob txha. Hydroxyapatite, uas muaj phosphoric acid residue, yog ib qho tseem ceeb ntawm cov pob txha cov pob txha. Tsis tas li ntawd, cov tshuaj no muaj calcium ions, uas txhawb lub zog ntawm lub cev pob txha.

Phospholipids ntawm daim nyias nyias yog lub hauv paus ntawm tag nrho txheej txheem. Cov txheej txheem bilipid dictates xws li cov khoom ntawm MCP ua cov khoom zoo, qhov kev kaw qhov muag, thauj cov tshuaj. Phospholipids yog lub luag hauj lwm rau qee yam hom passive thauj los ntawm daim nyias nyias. Tsis tas li ntawd nyob rau hauv lub thickness ntawm CPM yog ib qho tseem ceeb thiab cov nqaij nruab nrab ib nrab.

Nucleic acids yog lub hauv paus ntawm cov ntaub ntawv tshuaj ntsuam. Cov lwg me muaj cov sim yooj yim ntawm cov nucleotide, uas muaj cov phosphorus seem. Lawv ua si ib qho tseem ceeb hauv kev tsim cov phosphodiester bonds ntawm DNA thiab RNA molecules, tsis muaj lub qauv qauv yuav tsis yooj yim.

Lub luag hauj lwm lom ntawm phosphorus yog txuam nrog cia cov hluav taws xob hauv lub xov tooj ntawm tes. Qhov no yuav ua rau cov synthesis ntawm ATP, molecule uas muaj peb seem ntawm phosphoric acid. Lawv muaj kev cuam tshuam los ntawm txoj kev ua lag luam (macroergic bonds), uas lub zog khaws cia. ATP yog ua ke hauv mitochondria hauv cov tsiaj txhu, nrog rau hauv chloroplasts ntawm cov nroj tsuag, uas ua rau lub cev nqaij daim tawv tau muab los ntawm lub zog ntawm cov hluav taws xob. Yog tias ib qho ntawm cov phosphoric acid cleaved, lub molecule hu ua ADP (adenosine diphosphate), thiab yog tias ob residues cleaved, ces ATP tau hloov mus rau AMP (adenosine monophosphate).

Lub luag hauj lwm me ntsis ntawm phosphorus yog txuam nrog kev ua hauj lwm ntawm qhov kev xav ntawm lub paj hlwb thiab lub cev nqaij. Cov tshuaj no yog ib qho tseem ceeb ntawm qee lub enzymes, uas yog qhov tsim nyog rau txoj kev tshua ntawm lub cev.

Tsis muaj thiab tshaj ntawm phosphorus

Cov phosphorus cov ntsiab lus nyob rau hauv lub cev yuav tsum nyob ruaj khov thiab nyob rau hauv ib qho chaw. Yog tias muaj kev nce hauv qhov kev xav ntawm lub caij, qee cov kab mob tsim. Ntawm lawv, mob raum, Addison tus kab mob, mob ntshav qab zib mellitus, acromegaly.

Txo tus nqi ntawm phosphorus ua rau kev loj hlob ntawm high parathyroid kev ua si, thiab raws li ib tug xov tooj ntawm lwm yam kab mob.

Lub lom luag hauj lwm ntawm phosphorus yog nyob rau hauv kev tswj ib tug tas mus li puag ncig ntawm cov ntshav. Qhov tsis zoo system yuav tsum comprise seem ntawm phosphoric acid, thiaj li concentration ntawm lub caij yuav tsum tau khaws cia hais txog ntawm qhov kev tshwm sim. Nws yog pov thawj tias nyob rau hauv qhov tsis phosphorus lub cev yuav siv nws los ntawm lub hlwb ntawm cov nqaij mos. Nyob rau tib lub sij hawm, nws cov concentration nyob rau hauv cov ntshav yog ib txwm tas mus li los yog txawv nyob rau hauv ib tug nqiam ntau. Thiab tsuas yog nrog 40% ntawm txhua qhov phosphorus hauv lub cev xwb, cov ntshav tsuas yog 10% ntawm nws cov hnyav.

Nitrogen thiab nws cov dej num hauv lub cev

Lub luag hauj lwm loj ntawm nitrogen - kev tsim cov proteins thiab cov amino acids. Cov lwg me me no yuav tsum muaj cov amino pawg, uas muaj cov tshuaj no. Proteins ua ntau lub zog. Piv txwv, lawv yog ib feem ntawm cov cell thiab organelle membranes, pab thauj khoom sib xyaw rau lwm yam tshuaj, ua ib lub teeb liab, ua kom txhua yam biochemical haum hauv daim ntawv enzymes.

Amino acids yog monomers proteins. Nyob hauv lub xeev dawb, lawv tuaj yeem ua haujlwm qee yam. Tsis tas li cov amino acids yog cov precursors ntawm cov tshuaj hormones li adrenaline, noradrenaline, triiodothyronine thiab thyroxine.

Nitrogen muaj ib qho cwj pwm zoo rau kev ua hauj lwm ntawm cov hlab plawv. Nws txhawb nqa lub elasticity ntawm cov hlab ntsha, ntshav siab. Nitric oxide TSIS yog ib tug neurotransmitter nyob rau hauv lub paj hlwb axons hlwb.

Xaus

Lub luag hauj lwm me nyuam ntawm nitrogen thiab phosphorus yog los tswj cov txheej txheem tseem ceeb ntawm lub cev. Cov ntsiab lus no tseem ceeb heev rau cov organic molecules, xws li cov nqaijrog, cov nucleic acids lossis cov pab pawg ntawm lipids. Yog hais tias nitrogen tswj cov hemodynamics, ces phosphorus yog lub luag hauj lwm rau lub synthesis ntawm lub zog thiab yog lub hauv paus ntawm pob txha nqaij.
