Qhov sib txawv tseem ceeb ntawm lecithin thiab cephalin yog lecithin muaj cov amino cawv thiab choline, thaum cephalin muaj cov amino cawv, serine, lossis ethanolamine.
Lecithin thiab cephalin yog cov organic tebchaw tseem ceeb. Cov tshuaj no muaj lub luag haujlwm tseem ceeb hauv lub cev. Lecithin yog ib pawg ntawm cov roj ntsha daj-xim av uas tshwm sim hauv cov tsiaj thiab cov ntaub so ntswg uas muaj amphiphilic thiab muaj txiaj ntsig zoo rau kev ua kom zoo nkauj ntawm cov zaub mov. Cephalin yog ib chav kawm ntawm phospholipids uas tuaj yeem pom nyob rau hauv daim nyias nyias.
Lecithin yog dab tsi?
Lecithin yog ib pawg ntawm cov roj ntsha daj-xim av uas tshwm sim hauv cov tsiaj thiab cov nroj tsuag cov ntaub so ntswg uas yog amphiphilic thiab muaj txiaj ntsig zoo rau kev ua kom zoo nkauj ntawm cov khoom noj. Amphiphilic txhais tau tias nws tuaj yeem nyiam cov dej thiab cov rog rog. Ntxiv nrog rau kev ua kom zoo nkauj ntawm cov zaub mov, nws kuj tseem siv tau rau hauv emulsifying, homogenizing kua mixs, thiab repelling sticking cov ntaub ntawv.
Cov tshuaj no tau raug cais tawm thawj zaug hauv xyoo 1845 los ntawm Fab Kis Chemist thiab kws muag tshuaj Theodore Gobley. Nws kuj tau piav qhia txog qhov tshwm sim ntawm cov tshuaj no hauv ntau yam khoom siv lom neeg xws li cov ntshav venous, tib neeg lub ntsws, cov kua tsib, tib neeg lub hlwb cov ntaub so ntswg, ntses qe, ntses roe, nqaij qaib, thiab lwm yam.
Daim duab 01: Soy Lecithin
Ntxiv mus, peb tuaj yeem rho tawm cov tshuaj lecithin siv cov kuab tshuaj xws li hexane, ethanol, acetone, roj av ether, lossis benzene. Peb tuaj yeem ua qhov kev rho tawm no mechanically thiab. Cov khoom noj rau lecithins muaj xws li qe qe, zaub mov hauv hiav txwv, taum pauv, mis nyuj, rapeseeds, paj rwb, thiab roj sunflower.
Cov khoom tseem ceeb ntawm lecithin yog emulsification thiab lubricant zog. Cov tshuaj no tuaj yeem ua tiav los ntawm tib neeg, thiab nws tau txais txiaj ntsig zoo los ntawm tib neeg thiab tsis muaj tshuaj lom thaum noj.
Cephalin yog dab tsi?
Cephalin yog ib chav kawm ntawm phospholipids uas tuaj yeem pom hauv cov kab mob lom. Nws tseem hu ua phosphatidylethanolamine. Peb tuaj yeem tsim cov tshuaj no los ntawm kev sib ntxiv ntawm cytidine diphosphate-ethanolamine nrog diglycerides. Qhov no tso tawm cytidine monophosphate. Ntxiv mus, S-adenosyl methionine tuaj yeem ua rau methylate amine ntawm cephalin los ua phosphatidylcholine. Tsis tas li ntawd, peb tuaj yeem pom nws feem ntau hauv cov nplooj ntawv sab hauv ntawm lipid bilayer.
Daim duab 02: Biosynthesis ntawm txawv Phospholipids suav nrog Cephalin
Peb tuaj yeem pom qhov sib xyaw no hauv txhua lub hlwb nyob; Nws muaj li ntawm 25% ntawm tag nrho cov phospholipids. Hauv tib neeg, peb tuaj yeem pom cov khoom no, tshwj xeeb tshaj yog nyob rau hauv cov ntaub so ntswg thiab cov leeg txha caj qaum; Nws tsim txog li 45% ntawm tag nrho cov phospholipids. Hauv daim nyias nyias fusion, cephalin muaj lub luag haujlwm tseem ceeb. Nws tseem yog ib qho tseem ceeb nyob rau hauv lub disassembly ntawm lub contractile nplhaib thaum lub sij hawm cytokinesis nyob rau hauv cell division.
Qhov txawv ntawm Lecithin thiab Cephalin yog dab tsi?
Lecithin thiab cephalin yog cov organic tebchaw tseem ceeb. Cov tshuaj no muaj lub luag haujlwm tseem ceeb hauv tib neeg lub cev. Qhov sib txawv tseem ceeb ntawm lecithin thiab cephalin yog lecithin muaj cov amino cawv thiab choline, thaum cephalin muaj cov amino cawv, serine, lossis ethanolamine. Ntxiv mus, lecithin muaj txiaj ntsig zoo hauv cov txheej txheem metabolic thiab txav cov rog, thaum cephalin muaj txiaj ntsig zoo hauv kev kho cov kab mob hauv lub cev.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm lecithin thiab cephalin hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Lecithin vs Cephalin
Lecithin yog ib pawg ntawm cov roj ntsha daj-xim av uas tshwm sim hauv cov tsiaj txhu thiab cov nroj tsuag cov ntaub so ntswg uas muaj amphiphilic thiab muaj txiaj ntsig zoo rau cov khoom noj kom zoo nkauj. Cephalin yog ib chav kawm ntawm phospholipids uas tuaj yeem pom nyob rau hauv daim nyias nyias. Qhov sib txawv tseem ceeb ntawm lecithin thiab cephalin yog tias lecithin muaj cov amino cawv thiab choline, thaum cephalin muaj cov amino cawv, serine, lossis ethanolamine.
