Dab tsi yog noog lub zes acid (sialic acid)?
Noog lub zes acid, tseem hu ua sialic acid (SA), lub npe scientific yog "N-acetylneuraminic acid", molecular mis: C11H19NO9. Nws yog ib qho amino monosaccharide nrog cuaj lub caj qaum thiab ib txwm muaj nyob hauv cov khoom noj xws li mis niam, noog lub zes, thiab cov khoom siv mis nyuj. Nws yog Ameslikas cais los ntawm mucin nyob rau hauv lub submandibular caj pas, li no lub npe sialic acid. Salivary acid feem ntau muaj nyob rau hauv daim ntawv ntawm oligosaccharides, glycolipids, los yog glycoproteins. Cov ntsiab lus sialic acid nyob rau hauv tib neeg lub hlwb yog siab tshaj, thiab cov ntsiab lus sialic acid nyob rau hauv cov teeb meem grey yog 15 npaug ntau dua li cov hauv nruab nrog cev xws li lub siab thiab lub ntsws. Cov khoom noj tseem ceeb ntawm sialic acid yog cov kua mis thiab cov noog lub zes, tsuas yog muaj cov kab nyob hauv cov mis nyuj, qe, thiab cheese. A 900g ntawm cov kua mis ib txwm muaj tsawg dua 0.5g ntawm sialic acid. Raws li kev tshawb fawb soj ntsuam, cov ntsiab lus ntawm sialic acid nyob rau hauv noog lub zes yog siab li 7% -13%, uas yog ntau dua li lwm yam zaub mov thiab yog lub luag hauj lwm tseem ceeb ntawm noog lub zes. Yog li ntawd, sialic acid tseem hu ua noog lub zes acid.
Dab tsi yog qhov cuam tshuam ntawm noog lub zes acid rau tib neeg lub cev?
01 Txhim khu kev tiv thaiv
Noog lub zes acid tuaj yeem txhim kho tib neeg kev tiv thaiv kab mob, tshwj xeeb tshaj yog rau cov menyuam yaus. Noog lub zes acid tuaj yeem ua ke nrog cov kab mob thiab cov kab mob los ntawm qee cov txheej txheem kom ua tiav cov teebmeem tiv thaiv thiab tiv thaiv.

Kev kho mob: Rau cov kab mob uas twb tau nkag mus rau hauv cov pa mucosa, noog lub zes acid tuaj yeem tiv thaiv lawv cov kev rov ua dua thiab tso tawm, ua lub luag haujlwm tua tus kab mob. Noog lub zes acid tau siv rau hauv ntau qhov chaw rau nws cov tshuaj tiv thaiv kab mob thiab kis kab mob, txhim kho kev tiv thaiv.
02 Txhawb plab hnyuv antibacterial thiab detoxification
Cov noog lub zes acid ntawm cov cell membrane cov protein ua lub luag haujlwm tseem ceeb hauv kev txhim kho lub peev xwm ntawm tes, tshem tawm cov kab mob cholera toxin, tiv thaiv kab mob Escherichia coli, thiab tswj lub neej ib nrab ntawm cov ntshav protein.
03 Txhim kho plab hnyuv muaj peev xwm nqus tau
Cov zaub mov muaj txiaj ntsig zoo thiab qee cov vitamins uas nkag mus rau hauv txoj hnyuv tau yooj yim khi rau cov noog lub zes acid uas tsis zoo, yog li txhim kho plab hnyuv muaj peev xwm ntawm cov vitamins thiab minerals.
04 "Lub Plawv Kub" rau Kev Txhim Kho Kev Txawj Ntse
Noog lub zes acid tuaj yeem txhawb txoj kev loj hlob ntawm kev nco thiab kev txawj ntse. Los ntawm kev cuam tshuam nrog lub hlwb cell membranes thiab synapses, noog lub zes acid ua rau cov tshuaj tiv thaiv ceev ntawm lub hlwb paj hlwb synapses, yog li txhawb kev loj hlob ntawm kev nco thiab kev txawj ntse.
05 Ua Neej Nyob
Noog lub zes acid muaj kev tiv thaiv thiab stabilizing cov hlwb, thiab qhov tsis muaj sialic acid tuaj yeem ua rau txo qis hauv cov ntshav cell lifespan thiab glycoproteins hauv cov metabolism.
