phospholipid yog dab tsi?
Phospholipid yog ib feem ntawm lub cev hlwb. Nws tau tshawb pom los ntawm Uauquelin hauv tib neeg lub hlwb hauv xyoo 1812. Nyob rau xyoo 1844, Fabkis tus txiv neej Gohley thawj zaug cais exogenous phospholipid Cheebtsam ntawm qe qe, yog li nws tau hu ua lecithin. Txoj kev naming ntawm lecithin tau txuas ntxiv mus ntev, thiab txawm tias niaj hnub no, ntau tus neeg tseem tsis tuaj yeem paub qhov txawv ntawm "phospholipid tsev neeg". Qhov tseeb, nyob rau hauv qhov tseeb, lecithin tsuas yog ib feem ntawm phospholipids, thiab phospholipids kuj muaj xws li cephalin thiab phosphatidylinositol.
Thaum hais txog phospholipids, peb yuav tsum tham txog cov cell thiab cell membranes. Vim hais tias tag nrho cov kab mob - tsiaj txhu, nroj tsuag thiab cov kab mob, yog tsim los ntawm cov hlwb, txheej txheej ntawm lub cell hu ua cell membrane, thiab ntau organelles nyob rau hauv lub cell kuj muaj cov qauv membrane. Cov khoom tseem ceeb uas tsim cov txheej txheem membrane no yog phospholipids.
Cov khoom noj uas muaj phospholipids
Soybeans, nceb, qe yolks, walnuts, ceev, ntses roe, nqaij qaib, duck, ntses thiab tsiaj offal, thiab lwm yam.
Thaum tib neeg xub pom phospholipids, lawv nyob hauv qe qe, yog li lawv feem ntau hu ua "lecithin".
Tom qab ntawd, tib neeg pom tias taum pauv tau ntau dua thiab yooj yim dua kom tau txais cov txiaj ntsig ntawm lecithin. Yog li ntawd, feem ntau ntawm cov lecithin siv los ua ib qho ntxiv hauv kev lag luam lossis ua cov khoom noj khoom haus lossis cov khoom noj qab haus huv yog muab rho tawm los ntawm cov taum pauv, tab sis lub npe ntawm lecithin yog siv tawm ntawm tus cwj pwm.
Vim li cas nws yooj yim rau cov neeg niaj hnub no kom tsis muaj lecithin kom tsawg?
Vim muaj coob tus neeg niaj hnub txhawj xeeb txog kev rog rog thiab txhob txwm noj nqaij tsawg, tshwj xeeb tshaj yog cov nqaij rog, tsiaj offal, qe, thiab lwm yam.;
Nyob rau tib lub sijhawm, kev ua zaub mov niaj hnub no yog qhov zoo, thiab cov roj ua kom zoo, cov roj zaub xam lav, thiab lwm yam. txo cov qub nplua nuj lecithin;
Vim tias lecithin tsis tuaj yeem tiv taus cua sov, nws yooj yim poob nws cov haujlwm tom qab tshaj 50 degrees Celsius, thiab txoj kev ua noj yuav cuam tshuam rau kev noj haus;
Cov menyuam yaus thiab cov neeg laus feem ntau yuav muaj kev noj zaub mov tsis txaus vim lawv xaiv zaub mov tsawg thiab kev zom zaub mov thiab muaj peev xwm nqus tau;
Cov tub ntxhais kawm muaj lub nra hnyav rau kev kawm thiab siv lawv lub hlwb ntau dhau, thiab cov neeg ua haujlwm dawb-dhau muaj kev nyuaj siab ntau dhau hauv lub neej thiab kev ua haujlwm, uas yuav siv cov lecithin ntau thiab ua rau qhov xav tau ntau ntxiv.
Nyob rau tib lub sijhawm, peb txhua tus paub tias vim muaj hnub nyoog nce ntxiv, qhov kev puas tsuaj ntawm qhov chaw nyob thiab kev cuam tshuam ntawm kev ua neej nyob tsis zoo, ntau cov dawb radicals raug tsim tawm hauv tib neeg lub cev. Dawb radicals yuav ncaj qha oxidize cov phospholipids ntawm lub cell membrane, ua kev puas tsuaj rau lub cell membrane qauv, thiab ces ncaj qha cuam tshuam rau lub physiological kev ua ntawm lub cell. Qee tus neeg piv txwv piv phospholipid PC rau "cov khoom siv ntawm lub cell membrane". Kev xyuam xim rau kev noj cov phospholipid PC yuav muaj txiaj ntsig zoo rau ntau yam ntawm peb lub cev ua haujlwm.
tsev neeg phospholipid
Cov phospholipids peb feem ntau tham txog yog lub tswv yim ntawm kev sib xyaw, uas suav nrog ntau yam phospholipid cov khoom xyaw uas muaj cov qauv sib txawv thiab kev ua haujlwm.
Ntawm lawv yog: phosphatidylcholine (PC), phosphatidylinositol (PI), phosphatidylethanolamine (PE), phosphatidylserine (PS), phosphatidic acid (PA), thiab lwm yam. Feem ntau hais lus, lecithin hais txog ntau yam tshwj xeeb rau phosphatidylcholine (PC), vim nws muaj qhov siab tshaj plaws. cov ntsiab lus hauv phospholipid ua haujlwm pab pawg thiab tuaj yeem cuam tshuam rau tib neeg kev noj qab haus huv hauv ntau txoj hauv kev. Yog li ntawd, cov ntsiab lus ntawm phosphatidylcholine hauv cov khoom tau dhau los ua qhov tseem ceeb rau peb los txiav txim qhov sib txawv ntawm cov khoom siv lecithin.
Cov teebmeem kev noj qab haus huv ntawm phospholipids
1. Phospholipids yog indispensable rau cell membranes
Peb lub cev yog tsim los ntawm cov hlwb, thiab phospholipids yog cov khoom tseem ceeb ntawm cov cell membranes.
Tsis tas li ntawd, phospholipids ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa kev loj hlob ntawm cov ntaub so ntswg ntawm tes, ua kom cov hlwb, tswj cov metabolism, cov metabolism hauv basal thiab sib npaug ntawm cov tshuaj hormones, thiab txhim kho lub cev tiv thaiv kab mob thiab rov tsim dua tshiab.
2. Txhawb lub hlwb kev loj hlob
Phospholipids suav txog li 30%, thiab qhov kev faib ua feem hauv lub hlwb yog ntau dua, suav txog li 70-80%. Cov poj niam cev xeeb tub ntxiv phospholipids kuj tseem muaj txiaj ntsig zoo rau kev loj hlob ntawm fetal hlwb. Cias muab, koj ntse heev, thiab phospholipids tau pab!
Tsis tas li ntawd, qhov txo qis ntawm acetylcholine, ib qho neurotransmitter hauv lub hlwb, yog qhov ua rau Alzheimer's disease, thiab cov choline hauv phospholipids tuaj yeem ua ke nrog acetyl hauv tib neeg lub cev kom tau txais acetylcholine, yog li muab lub hlwb nrog cov ntaub ntawv xa mus txaus, uas. Nws muaj txiaj ntsig zoo rau cov neeg mob Alzheimer's disease.
3. Cov hlab ntsha scavenger
Cov roj (cholesterol) ntau dhau hauv cov ntshav yog qhov ua rau mob arteriosclerosis.
Cov roj (cholesterol) yog txuas mus rau cov hlab ntsha ntawm tib neeg lub cev xws li nplai. Nyob rau tib lub sijhawm, nws yuav ua rau cov hlab ntsha tsis tshua muaj zog, cov ntshav tsis txaus, thiab ua rau cov kab mob plawv thiab hlwb. Ntshav siab, thrombosis, cerebral hemorrhage thiab lwm yam kab mob yog tshwm sim los ntawm ntau cov roj cholesterol thiab lipids tso rau ntawm phab ntsa ntawm cov hlab ntsha.
Ib yam li cov tshuaj ntxuav tes tuaj yeem ntxuav cov nplai, phospholipids tuaj yeem emulsify cov rog nruab nrab thiab tso cov roj cholesterol rau hauv cov khoom uas tsis muaj teeb meem rau tib neeg lub cev, yaj hauv dej thiab yooj yim rau metabolize; Nyob rau tib lub sijhawm, nws inhibits qhov tso tawm ntawm cov roj ntau dhau ntawm phab ntsa ntawm cov hlab ntsha thiab txo qhov siab ntawm cov hlab plawv thiab cov hlab ntsha.
4. Anti-aging
Lub hauv paus ua rau tib neeg aging yog cell aging.
Cov txheej txheem ntawm lub voj voog tas mus li ntawm kev tuag ntawm tes thiab kev tsim dua tshiab yog cov txheej txheem ntawm kev noj cov phospholipids tas li. Yog tias cov phospholipids noj los ntawm tib neeg txhua hnub tsis tau ntxiv, cov hlwb yuav nyob rau hauv lub xeev ntawm kev noj zaub mov tsis txaus, tsis muaj zog, thiab maj mam tuag, thaum kawg ua rau kev laus ntawm tib neeg lub cev.
Kev siv thaj chaw ntawm phospholipids
1. Cov kua nplaum thiab cov khoom siv mis nyuj yog cov chaw ntawm phospholipids. Lawv cov khoom zoo emulsifying ua rau cov roj ntsha sib npaug sib npaug, ua rau lawv muaj dej ntau dua thiab ruaj khov.
2. Rau cov khoom ci, lecithin tuaj yeem txhim kho cov yam ntxwv ntawm kev ua khob noom cookie, ua kom cov dej xa tawm ntau dua, thiab tsim cov txheej txheem nrog cov protein kom ruaj khov ntawm cov khoom. Tsis tas li ntawd, lecithin tuaj yeem ua rau cov khoom ci tau yooj yim rau demould thiab muaj qhov zoo nkauj thiab zoo nkauj.
3. Rau cov khoom qab zib, chocolates, thiab lwm yam., emulsifiers feem ntau yog siv cov khoom qab zib, chocolates, thiab lwm yam, uas tuaj yeem ua rau cov khoom sib npaug sib npaug tsis ua rau qab zib thiab sib cais.
