Lecithin hmoov (8002-43-5) Cov Lus Qhia dav dav

Zaub mov-qib lecithin yog tau los ntawm taum pauv thiab lwm yam khoom cog. Nws yog cov sib xyaw ua ke ntawm acetone-insoluble phosphatides uas muaj thawj cov phosphatidyl choline, phosphatidyl etha nolamine, thiab phosphatidyl inositol, ua ke nrog ntau cov nqi ntawm lwm yam tshuaj xws li triglycerides, fatty acids, thiab carbohydrates. Qib rov qab ntawm lecithin tuaj yeem muaj ib feem ntawm cov sib txawv no kom muaj ntau qhov sib txawv thiab sib xyaw nyob ntawm seb siv cov zauv seem npaum li cas. Nyob rau hauv nws cov roj-dawb daim ntawv, tso cai ua ntej ntawm kev tawm tsam triglycerides thiab fatty acids uas yog raug tshem tawm thiab cov khoom muaj 90% lossis ntau dua ntawm phosphatides sawv cev rau tag nrho lossis qee feem ntawm tag nrho cov phosphatide. Qhov sib xyaw ua ke ntawm ob qib ntuj thiab qib siab ntawm lecithin tuaj yeem sib txawv ntawm cov yas mus rau kua, nyob ntawm cov roj ntsha dawb thiab roj cov ntsiab lus, thiab raws li qhov muaj los yog tsis muaj lwm yam tsis zoo. Nws cov xim nws txawv ntawm lub teeb daj mus rau xim av, nyob ntawm lub hauv paus, ntawm cov qoob loo hloov pauv, thiab nyob ntawm seb nws puas los yog ntxuav. Nws muaj ntxhiab tsw lossis muaj tus yam ntxwv, ntxhiab tsw zoo li txiv ntseej thiab lub siab ntsim. Cov khoom noj tau zoo, xws li cocoa butter thiab roj zaub, feem ntau hloov cov roj taum pauv los txhim kho cov txiaj ntsig zoo thiab ua kom hnov ​​qab ntawm tus kheej. Lecithin tsuas yog ib nrab soluble hauv dej, tab sis nws yooj yim hydrates los ua emulsions. Cov roj-dawb phosphatides yog soluble hauv cov roj ntsha, tab sis tau xyaum hauv cov roj tsis ruaj. Thaum tag nrho cov phosphatide feem tam sim no, lecithin yog ib feem soluble hauv cawv thiab xyaum ua cov tsis muaj tshuaj nyob hauv acetone.

 

Lecithin hmoov (8002-43-5) Keeb Kwm

Lecithin tau ua ntej cais nyob rau xyoo 1845 los ntawm Fabkis tus kws tshuaj thiab kws tshuaj Théodore Gobley. Xyoo 1850, nws tau tis npe rau phosphatidylcholine lécithine. Gobley keeb kwm cais lecithin los ntawm lub qe qe - λέκιθος lekithos yog "qe lub qe" hauv Greek Greek - thiab tsim cov tshuaj ua kom muaj tshuaj phosphatidylcholine thaum xyoo 1874; nyob rau hauv nruab nrab, nws tau ua pov thawj tias muaj lecithin nyob rau hauv ntau yam ntawm kev lom neeg, suav nrog cov leeg ntshav, hauv tib neeg lub ntsws, cov nqaj, tib neeg lub hlwb cov nqaij, cov qe ntses, ntses roe, thiab nqaij qaib thiab yaj hlwb.

 

Lecithin hmoov (8002-43-5) Mechanism Ntawm Kev Ua

Lecithin (phosphatidylcholine) yog ib qho ua ntej rau choline. Xws li, nws tau koom nrog hauv cov tshuaj ntawm cov neurotransmitter acetylcholine, thiab qib ntawm lecithin sib txheeb nrog cov qib choline thiab acetylcholine. Thiaj li, ib qho kev xav los ntawm kev ua ntawm lecithin yog qhov nce ntawm cov khoom cua, tso tawm, thiab muaj cov acetylcholine. Txawm li cas los xij, lecithin tseem tuaj koom rau hauv cov txheej txheem ua haujlwm tsis yooj yim, suav nrog cov cai ntawm cellular membrane permeability. Raws li tau tham txog saum toj no, cov neeg mob uas muaj kev puas siab puas ntsws bipolar qhia kev hloov pauv phospholipid metabolism, thiab cov choline qis dua nyob rau hauv orbital frontal grey teeb meem tau pom nyob hauv cov neeg mob uas muaj cov tsos mob manic. Yog li, kev txhawb ntxiv nrog lecithin thaj ua rau lub ntsws puas tsuaj thiab hloov lub peev xwm.

Lecithins kuj tseem siv tau los ua kev sib koom ua ke ntawm cov khoom noj khoom haus rau cov khoom noj thiab ua niam txiv.

Muaj cov ntaub ntawv pov thawj tias phosphatidylcholine (ib qho tseem ceeb ntawm lecithin) yog qhov tseem ceeb uas yog cov khoom noj muaj txiaj ntsig rau kev loj hlob ntawm tus me nyuam hauv plab thiab menyuam mos. Ntxiv mus, choline yog qhov xav tau ntawm FDA-pom zoo cov mis mos qauv. Lwm qhov kev tshawb fawb tau qhia tias lecithin tuaj yeem tiv thaiv kev haus cawv hauv lub siab, txo qis cov roj cholesterol ntau, thiab txhim kho lub hlwb thiab lub cev.

Liposomes nyob rau hauv uas lecithin suav nrog ua ib feem ntawm cov bilayer tau siv los encapsulate yeeb tshuaj; Lawv cov peev txheej raws li lub tshuab xa xov tshiab tau raug tshawb xyuas qhov tseeb. Daim ntawv thov no feem ntau yuav tsum tau lim cov lecithins ua ke hauv cov qib tshwj xeeb.

Kho, lecithin thiab derivatives tau siv los ua pulmonary surfactant hauv kev kho tus mob neonatal pa nyuaj siab.
