Qhov sib txawv tseem ceeb ntawm DL alpha tocopheryl acetate thiab D alpha tocopherol yog tias DL alpha tocopheryl acetate tshwm sim raws li cov khoom sib xyaw sib xyaw sib xyaw thaum D alpha tocopherol yog ib qho khoom siv ntuj tsim.
DL alpha tocopheryl acetate yog ib qho derivative ntawm D alpha tocopherol. Nws yog ib daim ntawv ester ntawm D alpha tocopherol. Txawm hais tias qhov bioavailability ntawm ob lub tebchaw yog ze li ntawm ib leeg, muaj qhov sib txawv ntawm DL alpha tocopheryl acetate thiab D alpha tocopherol.
DL Alpha Tocopheryl Acetate yog dab tsi?
DL alpha tocopheryl acetate yog ib hom kev sib tw ntawm D thiab L cov ntaub ntawv ntawm alpha tocopheryl acetate. Li no, nws yog ib daim ntawv ntawm ib tug hluavtaws sib tov ntawm tocopherol molecules, thiab nws yog ib qho ntawm cov muaj zog tshaj plaws antioxidant tocopherols. Cov tshuaj formula ntawm alpha tocopheryl acetate (D lossis L daim ntawv) yog C31H52O3 Yog li. Cov molar mass ntawm no compound yog 472.754 g / mol.
Daim duab 01: Cov qauv ntawm Alpha Tocopheryl Acetate
Cov haujlwm antioxidant ntawm cov tshuaj no yog vim muaj phenolic hydrogen ntawm 2H-1-benzopyran-6-ol nucleus. Ntxiv mus, nws muaj plaub pawg methyl ntawm 6-chromanol nucleus thiab. Txawm li cas los xij, lub ntuj D daim ntawv ntawm alpha-tocopherol muaj zog ntau dua li qhov sib xyaw racemic. Tsis tas li ntawd, qhov sib xyaw racemic no muaj alpha tocopherol hauv nws daim ntawv ester (acetate ester), yog vim li cas peb hu nws DL alpha tocopheryl acetate. Tsis tas li ntawd, qhov sib xyaw no tiv taus ntau dua rau oxidation; Yog li, cov tshuaj uas muaj daim ntawv acetate no muaj lub neej ntev. Txawm li cas los xij, qhov bioavailability ntawm cov tshuaj no yog ze li ntawm daim ntawv dawb alpha-tocopherol.
D Alpha Tocopherol yog dab tsi?
D alpha tocopherol yog vitamin E, thiab nws yog ib txwm muaj. Cov tshuaj formula yog C29H50O2. Yog li, molar mass yog 430.717 g / mol. Ntxiv mus, nws yog ib tug fat-soluble vitamin.
Daim duab 02: Cov qauv ntawm Alpha-Tocopherol
Tsis tas li ntawd, nws yog ib qho muaj zog antioxidant uas ntseeg tau tias tseem ceeb hauv kev tiv thaiv cov hlwb los ntawm oxidative kev nyuaj siab. Tsis tas li ntawd, qhov no yog daim ntawv nquag nquag thiab feem ntau bioavailable daim ntawv ntawm tocopherol. Yog li ntawd, peb lub cev nyiam nqus thiab siv daim ntawv no. Tsis tas li ntawd, nws zoo nkaus li cov kua dej daj-xim av. Lub melting point thiab boiling point yog 3.5 ° C thiab 200 mus rau 220 ° C raws.
Qhov txawv ntawm DL Alpha Tocopheryl Acetate thiab D Alpha Tocopherol yog dab tsi?
DL alpha tocopheryl acetate yog ib hom kev sib tw ntawm D thiab L cov ntaub ntawv ntawm alpha tocopheryl acetate thaum D alpha tocopherol yog vitamin E, thiab nws yog ib txwm muaj. Qhov sib txawv tseem ceeb ntawm DL alpha tocopheryl acetate thiab D alpha tocopherol yog tias DL alpha tocopheryl acetate tshwm sim raws li cov khoom sib xyaw sib xyaw sib xyaw thaum D alpha tocopherol yog cov khoom siv ntuj tsim. Ntxiv mus, lub ntuj D daim ntawv ntawm alpha-tocopherol yog active tshaj DL alpha tocopheryl acetate.
Raws li lwm qhov sib txawv tseem ceeb ntawm DL alpha tocopheryl acetate thiab D alpha tocopherol, DL alpha tocopheryl acetate muaj nyob rau hauv cov ntaub ntawv khoom thaum D alpha tocopherol nyob rau hauv daj-xim av kua nplaum. Cov ntaub ntawv hauv qab no muab cov lus qhia ntxiv txog qhov sib txawv ntawm DL alpha tocopheryl acetate thiab D alpha tocopherol.
Summary – DL Alpha Tocopheryl Acetate vs D Alpha Tocopherol
DL alpha tocopheryl acetate yog ester derivative ntawm D alpha tocopherol. Qhov sib txawv tseem ceeb ntawm DL alpha tocopheryl acetate thiab D alpha tocopherol yog tias DL alpha tocopheryl acetate tshwm sim raws li cov khoom sib xyaw sib xyaw sib xyaw thaum D alpha tocopherol yog ib qho khoom xyaw ntuj.
