Qhov sib txawv tseem ceeb ntawm saturated thiab unsaturated triglycerides yog tias saturated triglycerides tsuas muaj ib daim ntawv cog lus ntawm carbon atoms, whereas unsaturated triglycerides muaj ob los yog triple bonds ntawm carbon atoms.
Lub sij hawm saturated txhais tau hais tias cov pa roj carbon atoms nyob rau hauv lub molecule yog saturated nrog hydrogen los yog lwm yam atoms bonded nrog plaub covalent sigma bonds nyob ib ncig ntawm txhua carbon atom. Yog li ntawd, tsis muaj ob los yog triple bonds ntawm carbon atoms. Nyob rau hauv sib piv, unsaturated txhais tau tias cov pa roj carbon atoms tsis tag saturated nrog hydrogen los yog lwm yam atoms, yog li lawv tau tsim ob los yog triple bonds nyob ib ncig ntawm lawv.
YTriglycerides yog dab tsi?
Triglycerides yog ester compounds muab los ntawm glycerol thiab peb fatty acid chains. Cov tebchaw no yog cov khoom tseem ceeb ntawm lub cev rog hauv tib neeg thiab lwm cov vertebrates (thiab tseem muaj roj zaub). Tsis tas li ntawd, triglycerides muaj nyob hauv cov ntshav txhawm rau txhawm rau txhawm rau hloov pauv bidirectional ntawm adipose rog thiab ntshav qabzib los ntawm daim siab.
Muaj ntau ntau hom triglycerides, suav nrog saturated thiab unsaturated triglycerides, uas yog cais raws li qhov muaj los yog tsis muaj ob thiab triple bonds ntawm carbon atoms ntawm fatty acid carbon saw. Yog li ntawd, saturated triglycerides tsis muaj C=C bonds, thaum unsaturated triglycerides muaj ib los yog ntau tshaj C=C bonds.
YSaturated Triglycerides yog dab tsi?
Saturated triglycerides yog cov organic tebchaw uas tsis muaj ob lossis peb npaug ntawm cov pa roj carbon atoms hauv cov saw hlau. Cov triglycerides no muaj feem ntau ntawm saturated fatty acids hauv lawv cov qauv. Hauv lwm lo lus, saturated triglycerides yog saturated nrog sigma covalent bonds nyob ib ncig ntawm cov pa roj carbon atoms, thiab lawv kuj muaj ntau cov hydrogen atoms rau ib tug muab cov pa roj carbon atoms nyob rau hauv cov fatty acid chain structure.
Feem ntau, saturated triglycerides muaj lub siab melting point dua li cov ntaub ntawv tsis txaus ntseeg uas muaj qhov hnyav zoo sib xws. Yog li ntawd, saturated triglycerides feem ntau yuav muaj zog ntawm chav tsev kub. E.g. lom zem thiab os.
Dab tsi yog Unsaturated Triglycerides?
Unsaturated triglycerides yog cov organic tebchaw uas muaj ib lossis ntau dua ob lossis peb daim ntawv cog lus ntawm carbon atoms hauv cov saw hlau. Cov triglycerides no muaj feem ntau ntawm unsaturated fatty acids hauv lawv cov qauv. Yog li ntawd, unsaturated triglycerides tsis saturated nrog sigma covalent bonds nyob ib ncig ntawm carbon atoms; Yog li, lawv muaj tsawg kawg nkaus ntawm hydrogen atoms rau ib tug muab cov pa roj carbon atoms nyob rau hauv fatty acid saw qauv.
Peb tuaj yeem faib cov tshuaj no ntxiv rau hauv ob pawg ua monounsaturated triglycerides thiab polyunsaturated triglycerides. Daim ntawv monounsaturated tsuas muaj ib daim ntawv cog lus ob npaug rau cov saw hlau, thaum daim ntawv polyunsaturated tuaj yeem muaj ob lossis ntau dua ob daim ntawv cog lus rau cov saw hlau nyob hauv tib lub molecule.
Feem ntau, polyunsaturated triglycerides muaj cov ntawv thov tseem ceeb hauv kev lag luam khoom noj vim yog cov khoom noj khoom haus, tab sis tuaj yeem muaj qee qhov kev siv tsis yog khoom noj thiab. Cov ntawv thov tsis yog khoom noj muaj xws li kev tsim cov roj kom qhuav, suav nrog linseed, tung, poppy noob, perilla thiab walnut roj.
Peb tuaj yeem hloov pauv tsis txaus triglyceride rau hauv daim ntawv saturated los ntawm cov tshuaj tiv thaiv nrog hydrogen nyob rau hauv muaj cov catalyst. Nws yog lub npe hu ua txheej txheem hydrogenation. Peb tuaj yeem siv cov tshuaj tiv thaiv no los hloov cov roj zaub rau hauv cov roj zaub lossis cov roj semisolid xws li margarine.
Qhov txawv ntawm Saturated thiab Unsaturated Triglycerides yog dab tsi?
Cov ntsiab lus saturated thiab unsaturated hais txog qhov tsis muaj lossis muaj ob lossis peb daim ntawv cog lus ntawm carbon atoms, feem, hauv cov organic compound. Qhov sib txawv tseem ceeb ntawm saturated thiab unsaturated triglycerides yog tias saturated triglycerides tsuas muaj ib daim ntawv cog lus ntawm carbon atoms, whereas unsaturated triglycerides muaj ob los yog triple bonds ntawm carbon atoms.
Cov hauv qab no infographic suav qhov sib txawv ntawm cov saturated thiab unsaturated triglycerides nyob rau hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Saturated vs Unsaturated Triglycerides
Cov ntsiab lus saturated thiab unsaturated hais txog qhov tsis muaj lossis muaj ob lossis peb daim ntawv cog lus ntawm carbon atoms, feem, hauv cov organic compound. Qhov sib txawv tseem ceeb ntawm saturated thiab unsaturated triglycerides yog tias saturated triglycerides tsuas muaj ib daim ntawv cog lus ntawm carbon atoms, whereas unsaturated triglycerides muaj ob los yog triple bonds ntawm carbon atoms. Yog li ntawd, saturated triglycerides tsis muaj C=C bonds, thaum unsaturated triglycerides muaj ib los yog ntau tshaj C=C bonds.
