Qhov sib txawv tseem ceeb ntawm cov roj saturated thiab unsaturated fats yog cov roj saturated tsis muaj ob daim ntawv cog lus ntawm fatty acid chains thaum unsaturated fats muaj ob daim ntawv cog lus nyob rau hauv cov fatty acid chains.
Fat lossis lipid yog ib qho tseem ceeb macromolecule uas muaj lub hauv paus glycerol molecule thiab peb fatty acid chains txuas ua ke. Muaj ob hom rog raws li kev sib txuas ntawm cov molecules ntawm fatty acid chains; lawv yog cov rog saturated thiab unsaturated fats.
Dab tsi yog Saturated fats?
Cov rog rog yog hom rog uas tsis muaj ob daim ntawv cog lus ntawm cov molecules ntawm fatty acid chains. Txhua daim ntawv cog lus yog ib daim ntawv cog lus hauv cov rog no. Feem ntau cov khoom noj tsiaj muaj cov roj saturated. Lawv yog cov khoom nyob rau hauv chav tsev kub thiab muaj ib tug siab melting point piv rau unsaturated fats.
Daim duab 01: Saturated Fats
Tsis tas li ntawd, cov roj saturated kuj suav tias yog cov rog tsis zoo vim lawv tuaj yeem nce qib roj cholesterol hauv cov ntshav thiab tuaj yeem thaiv cov hlab ntsha, ua rau lub plawv nres thiab mob stroke. Butyric acid, palmitic acid, lauric acid, myristic acid yog ib co piv txwv ntawm saturated fatty acids.
Dab tsi yog Unsaturated fats?
Cov rog tsis txaus yog hom rog uas muaj ob daim ntawv cog lus ntawm C atoms ntawm fatty acid chains. Lawv nyob twj ywm li kua nyob rau hauv chav tsev kub. Cov zaub mov cog thiab ntses yog nplua nuj nyob rau hauv lawv. Lawv kuj muaj qhov qis melting point. Tsis tas li ntawd, cov roj unsaturated tsis nce qib roj cholesterol hauv peb cov ntshav lossis ua rau muaj kev pheej hmoo ntawm cov kab mob plawv. Li no, lawv ua cov rog muaj txiaj ntsig.
Daim duab 02: Unsaturated fats
Txawm li cas los xij, cov rog tsis muaj rog muaj tsis muaj cov ntsiab lus siab zog. Yog li, lawv muab cov calories tsawg. Palmitoleic acid, oleic acid, myristoleic acid, linoleic acid, thiab arachidonic acid yog ob peb yam piv txwv ntawm lawv.
Dab tsi yog qhov zoo sib xws ntawm Saturated thiab Unsaturated fats?
- Saturated thiab unsaturated fats muaj glycerol thiab fatty acids.
- Ob cov rog muaj nyob hauv peb cov zaub mov.
- Ob hom rog muab lub zog.
Qhov txawv ntawm Saturated thiab Unsaturated Fats yog dab tsi?

Summary – Saturated vs Unsaturated Fats
Zuag qhia tag nrho, qhov sib txawv ntawm cov roj saturated thiab unsaturated yog nyob rau hauv qhov tsis muaj thiab muaj ob daim ntawv cog lus ntawm C atoms ntawm fatty acid chains. Txij li cov roj saturated tuaj yeem nce qib roj cholesterol hauv cov ntshav thiab ua rau muaj kev pheej hmoo ntawm cov kab mob plawv, lawv feem ntau raug cais raws li cov rog tsis zoo. Unsaturated fats yog cov rog uas muaj txiaj ntsig muaj nyob hauv cov zaub mov uas muaj cov nroj tsuag thiab ntses.
