Qhov sib txawv tseem ceeb ntawm tocopherols thiab tocotrienols yog tias tocopherols muaj saturated isoprenoid sab chains, whereas tocotrienols muaj unsaturated isoprenoid sab chains.
Muaj ntau hom vitamin E. Lawv tuaj yeem tshwm sim feem ntau yog tocopherols lossis tocotrienols. Cov no yog cov tshuaj lom neeg tseem ceeb heev uas ua lub luag haujlwm tseem ceeb hauv cov txheej txheem biochemical uas tshwm sim hauv tib neeg lub cev.
Dab tsi yog Tocopherols?
Tocopherol yog ib hom organic compound uas los ntawm pawg methylated phenols. Ntau cov methylated phenols muaj vitamin E ua haujlwm. Qhov kev ua vitamin no tau coj mus rau nws lub npe thiab. Thaum xav txog lub hauv paus ntawm tocopherols, tshwj xeeb tshaj yog alpha-tocopherols, tshuaj thiab European zaub mov, uas yog nplua nuj nyob rau hauv txiv roj roj thiab sunflower roj, yog cov loj qhov chaw. Txawm li cas los xij, peb tuaj yeem pom gamma-tocopherols feem ntau hauv Asmeskas cov zaub mov, qhov twg taum pauv thiab pob kws roj tau txais kev sib piv siab heev.
Ntau qhov tseeb, vitamin E tuaj yeem tshwm sim hauv yim txoj kev sib txawv: plaub tocopherols thiab plaub tocotrienols. Tag nrho cov tebchaw no muaj cov qauv chromane nplhaib nrog cov pab pawg hydroxyl uas nyiam pub cov hydrogen atom los txo cov ntsiab lus dawb radical thiab cov saw hlau hydrophobic uas tuaj yeem tso cai nkag mus rau hauv cov kab mob lom.
Daim duab 01: Cov Qauv Tshuaj ntawm Alpha-Tocopherol
Feem ntau, alpha-tocopehrol tuaj yeem pom raws li qhov nyiam tshaj plaws ntawm cov vitamin E hauv tib neeg. Cov compound no muaj peb lub stereocenters, uas ua rau nws muaj chiral compound. Cov stereocenters no yog lub luag haujlwm rau qhov sib txawv ntawm kev npaj cov pab pawg nyob ib ncig ntawm lub stereocenter kom muab cov ntaub ntawv sib txawv tocopherol. Txawm li cas los xij, tocopherols yog ib qho tseem ceeb xws li radical scavengers uas tuaj yeem tua cov dawb radicals.
Dab tsi yog Tocotrienols?
Tocotrienols yog ib pawg ntawm cov organic tebchaw thiab ib hom vitamin E. Muaj plaub lub qauv loj ntawm cov ntaub ntawv no hu ua alpha, beta, gamma, thiab delta forms. Feem ntau, tocotrienols muaj unsaturated isoprenoid sab chains muaj peb carbon-carbon ob daim ntawv cog lus.
Daim duab 02: Cov Qauv Tshuaj ntawm Tocotrienol
Peb tuaj yeem pom cov vitamin E no feem ntau hauv cov roj zaub xws li txiv maj phaub roj, roj nplej, nplej gram, barley, pom palmetto, annatto, qee cov nplej, txiv ntoo, thiab lawv cov roj. Txawm hais tias cov ntaub ntawv sib txawv ntawm cov vitamin E qhia qee qhov kev ua haujlwm raws li cov tshuaj antioxidants, tag nrho cov qauv no tsis muaj qhov sib npaug ntawm cov vitamin E. Feem ntau, tocotrienols qhia kev ua si nyob ntawm seb hom kev ua haujlwm antioxidant uas raug ntsuas.
Dab tsi yog qhov zoo sib xws ntawm Tocopherols thiab Tocotrienols?
- Tocopherols thiab tocotrienols yog methylated phenols.
- Ob leeg tocopherols thiab tocotrienols muaj vitamin E ua haujlwm.
- Lawv yog fat-insoluble antioxidants.
Qhov txawv ntawm Tocopherols thiab Tocotrienols yog dab tsi?
Muaj ntau hom vitamin E uas tuaj yeem tshwm sim feem ntau yog tocopherols lossis tocotrienols. Cov no yog cov tshuaj lom neeg tseem ceeb heev uas ua lub luag haujlwm tseem ceeb hauv cov txheej txheem biochemical uas tshwm sim hauv tib neeg lub cev. Qhov sib txawv tseem ceeb ntawm tocopherols thiab tocotrienols yog tias tocopherols muaj saturated isoprenoid sab chains, whereas tocotrienols muaj unsaturated isoprenoid sab chains.
Cov duab hauv qab no nthuav tawm qhov sib txawv ntawm tocopherols thiab tocotrienols hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Tocopherols vs Tocotrienols
Peb tuaj yeem pom ntau hom vitamin E uas tuaj yeem tshwm sim feem ntau yog tocopherols lossis tocotrienols. Tocopherols yog cov organic tebchaw uas tuaj nyob rau hauv pawg ntawm methylated phenols. Tocotrienols yog ib pawg ntawm cov organic tebchaw thiab ib hom vitamin E. Qhov sib txawv tseem ceeb ntawm tocopherols thiab tocotrienols yog tias tocopherols muaj saturated isoprenoid side chains, whereas tocotrienols muaj unsaturated isoprenoid side chains.
