Qhov sib txawv tseem ceeb ntawm choline thiab phosphatidylcholine yog tias choline yog quaternary ammonium compound thaum phosphatidylcholine yog cov derivative ntawm choline ua los ntawm choline thiab phosphoglyceric acid.
Choline thiab phosphatidylcholine yog cov khoom tseem ceeb hauv cov qauv ntawm eukaryote. Ob leeg ua lub luag haujlwm tseem ceeb hauv daim nyias nyias dynamics thiab membrane physiology ntawm cell. Vim nws lub luag haujlwm tseem ceeb hauv physiology, nws yog ib qho tseem ceeb kom tau txais cov khoom noj kom zoo los ntawm kev noj zaub mov ntxiv.
Choline yog dab tsi?
Choline yog ib qho khoom noj tseem ceeb rau cov nroj tsuag thiab tsiaj txhu. Nws yog quaternary ammonium compound uas yog hygroscopic nyob rau hauv cov xwm. Choline yog ib qho xim tsis muaj xim thiab ruaj khov hauv cov kua dej. Lub compound choline tshwm sim ua ib qho cation. Daim ntawv muaj choline hauv kev noj haus yog phospholipids lossis phosphatidylcholine. Txawm li cas los xij, de Novo ntau lawm ntawm choline kuj tshwm sim hauv cov nroj tsuag thiab tsiaj txhu.
Metabolism ntawm choline tshwm sim zoo ib yam li cov amino acids. Kev nqus choline tshwm sim hauv cov hnyuv, qhov chaw uas lawv tau ua kom yooj yim diffusion. Thaum nkag mus rau hauv cov hlab ntsha, lawv thauj dawb.
Daim duab 01: Choline
Lub luag haujlwm lom neeg ntawm choline yog cov qauv tsim. Lawv tsim cov phospholipid bilayer thiab pab cov txheej txheem membrane stability rau ntau yam organelles. Ntxiv mus, nws kuj yog ib feem ntawm cov neurotransmitter acetylcholine thiab s-adenosyl methionine, uas yog ib qho tseem ceeb nyob rau hauv lub synthesis ntawm homocysteine.
Qhov chaw nplua nuj tshaj plaws ntawm choline yog qe, ntau dua lub qe qe. Ntxiv rau qhov no, nqaij, nplej, zaub thiab txiv hmab txiv ntoo kuj muaj cov ntsiab lus siab ntawm choline. Choline deficiency yog ib yam mob uas tsis tshua muaj neeg. Txawm li cas los xij, nws tuaj yeem ua rau tsis muaj dej cawv fatty siab kab mob thiab kev puas tsuaj rau cov leeg.
Phosphatidylcholine yog dab tsi?
Phosphatidylcholine yog ib hom phospholipid. Lub taub hau ntawm nws yog quaternary ammonium compound. Tsis tas li ntawd, phosphatidylcholine tseem hu ua lecithin. Cov qauv ntawm phosphatidylcholine muaj ib pawg thawj coj ntawm choline thiab glycerophosphoric acid. Nws yog saturated fatty acid. Lawv yog daj-xim av fatty tshuaj.
Daim duab 02: Phosphatidylcholine
Phosphatidylcholine feem ntau tau los ntawm kev noj zaub mov xws li qe, nqaij, zaub thiab nplej. Txawm li cas los xij, de novo synthesis ntawm phosphatidylcholine kuj tshwm sim hauv eukaryotes.
Lub luag haujlwm lom neeg ntawm phosphatidylcholine sib txawv sai. Nws ua raws li cov txheej txheem hauv cov plasma membrane ntawm eukaryotes. Txawm li cas los xij, phosphatidylcholine tsis muaj nyob hauv cov kab mob. Tsis tas li ntawd, nws tseem yog ib feem tseem ceeb ntawm pulmonary surfactant. Phosphatidylcholine kuj tseem ua haujlwm hauv kev taw qhia thiab ua cov teeb liab ntawm tes.
Dab tsi yog qhov zoo sib xws ntawm Choline thiab Phosphatidylcholine?
- Choline thiab phosphatidylcholine ua raws li cov khoom siv.
- Lawv ua lub luag haujlwm tseem ceeb hauv daim nyias nyias physiology.
- Ob leeg nkag mus rau hauv cov ntshav ntawm txoj hnyuv.
- Lawv taug kev ywj pheej hauv ntshav.
- Ob leeg tau ua kom yooj yim diffusion thaum nqus.
- Ntxiv mus, lawv tuaj yeem raug tsim tawm ntawm novo hauv eukaryotic hlwb, suav nrog cov nroj tsuag thiab tsiaj.
- Tsis tas li ntawd, lawv tuaj yeem tau los ntawm kev noj haus.
- khoom noj xws li qe, nqaij, zaub thiab nplej muaj cov ntsiab lus siab ntawm ob qho tib si.
Qhov txawv ntawm Choline thiab Phosphatidylcholine yog dab tsi?
Ob leeg choline thiab phosphatidylcholine yog cov khoom tseem ceeb hauv lub cev, feem ntau hauv lub koom haum eukaryotic cellular. Qhov sib txawv tseem ceeb ntawm choline thiab phosphatidylcholine nyob hauv lawv cov qauv. Phosphatidylcholine yog ib qho derivative ntawm choline. Yog li ntawd, phosphatidylcholine yog ntau ntawm fatty acid thaum choline yog quaternary ammonium compound. Lawv lub luag haujlwm tseem ceeb yog kev tsim qauv. Txawm li cas los xij, cov haujlwm tshwj xeeb txawv hauv txhua qhov sib xyaw. Lwm qhov sib txawv ntawm choline thiab phosphatidylcholine yog tias choline muaj nyob rau hauv ob qho tib si eukaryotes thiab prokaryotes. Lub caij no, phosphatidylcholine tsis tuaj hauv prokaryotes.
Cov hauv qab no qhia txog qhov sib txawv ntawm choline thiab phosphatidylcholine.
Summary – Choline vs Phosphatidylcholine
Choline thiab phosphatidylcholine yog ob lub tebchaw uas yog qhov tseem ceeb hauv kev ua haujlwm ntawm daim nyias nyias. Yog li ntawd, muaj cov ntsiab lus tseem ceeb hauv physiology ntawm eukaryotes. Choline yog quaternary ammonium compound. Hauv qhov sib piv, phosphatidylcholine yog kev sib xyaw ntawm choline taub hau thiab phosphoglyceric acid. Ntxiv nrog rau kev ua cov txheej txheem, lawv kuj muaj ntau yam kev ua haujlwm metabolic. Kev noj zaub mov kom tsawg ntawm cov khoom no yog qhov tseem ceeb txhawm rau txhawm rau tswj kev sib npaug hauv txoj hauv kev metabolic. Yog li, qhov no qhia txog qhov sib txawv ntawm choline thiab phosphatidylcholine.
