Qhov sib txawv tseem ceeb ntawm carbohydrates thiab cov rog yog cov carbohydrates soluble hauv dej thaum cov rog feem ntau tsis soluble hauv dej.
Khoom noj khoom haus thiab koom nrog kev tshawb fawb yog riddled nrog kev thov kom txo qhov hnyav, nce qhov hnyav thiab toning lub cev. Cov ntsiab lus zoo li carbohydrates, rog, proteins, thiab vitamins yog cov ntsiab lus tshwj xeeb nrog rau kev tshawb fawb. Carbohydrates thiab rog yog ob lo lus uas hais txog ob lub macromolecules tseem ceeb rau peb lub cev.
Carbohydrates yog dab tsi?
Carbohydrates, tseem hu ua saccharides, yog cov organic tebchaw ua los ntawm carbon, hydrogen, thiab oxygen. Raws li tus naj npawb ntawm cov tsev blocks (monomers) hauv cov carbohydrate, lawv tuaj yeem yog monosaccharides, disaccharides, oligosaccharides lossis polysaccharides.
Daim duab 01: Carbohydrates
Carbohydrate monomers yog cov monosaccharides (cov suab thaj yooj yim). Qhov tseeb, lawv yog qhov yooj yim tshaj plaws ntawm tag nrho cov thiab pab txhawb kev tsim ntawm lwm hom. Monosaccharides suav nrog piam thaj thiab fructose. Tsis tas li ntawd, cov suab thaj yooj yim ua lub zog thiab cov khoom siv rau kev sib txuas. Glucose muaj xws li glycogen hauv peb lub cev. Hauv cov nroj tsuag, cov piam thaj muaj nyob hauv cov hmoov txhuv nplej siab. Tsis tas li ntawd, cov khoom noj uas muaj hmoov txhuv nplej siab feem ntau yog cov carbohydrates ntau thiab muab 4 kilocalories ib gram ntawm carbohydrate. Oligosaccharides pab tswj cov kab mob hauv plab, uas pab ua ke ntawm ntau yam khoom.
Fat yog dab tsi?
Cov rog yog cov organic sib xyaw ua ke ntawm carbon, hydrogen, thiab oxygen. Lub sij hawm rog suav nrog tag nrho cov lipids thiab roj, nrog rau, cov roj cholesterol esters. Muaj ob hom rog; saturated thiab unsaturated. Unsaturated fats muaj fatty acids chains uas muaj ob daim ntawv cog lus ntawm C atoms. Lawv hloov mus rau hauv lwm cov molecules yooj yim nrog rau kev ntxig ntawm ib tug branching molecule. Saturated fats tsis muaj ob daim ntawv cog lus ntawm C atoms ntawm lawv cov fatty acid chains.
Daim duab 02: Fats
Cov rog yog qhov tseem ceeb hauv kev tsim hluav taws xob, khaws cia lub zog, tiv thaiv cov cua sov, nqus cov as-ham xws li cov vitamins, thiab lwm yam. Cov rog tsim 9 kilocalories ib gram. Lawv nyiam ua ke lwm yam khoom thaum thauj mus rau lub siab. Tag nrho cov ntawm lawv yog ib qho tseem ceeb, tab sis nyob rau hauv qee zaus, ntau tshaj ntawm cov metabolites tuaj yeem ua rau tuag.
Dab tsi zoo sib xws ntawm Carbohydrates thiab rog?
- Carbohydrates thiab rog yog cov organic molecules.
- Lawv yog macromolecules tsim los ntawm monomers.
- Ob leeg muaj C, H thiab O atoms.
- Lawv yog lub zog.
- Ob leeg suav nrog rau hauv peb cov zaub mov.
- Ntau dhau ntawm ob hom tuaj yeem ua rau muaj kab mob.

Summary – Carbohydrates vs Fats
Carbohydrates thiab rog yog macromolecules uas muaj C, H, thiab O atoms. Lawv muab lub zog. Tsis tas li ntawd, carbohydrates yog dej soluble thiab ua lub zog tseem ceeb rau tag nrho cov kab mob nyob. Nyob rau hauv sib piv, cov rog yog tsis-soluble nyob rau hauv dej thiab yog tsawg ntshaw raws li lub zog qhov chaw. Tab sis lawv yog cov khw muag khoom hluav taws xob zoo. Carbs ua piv txwv tsawg zog ib gram. Qhov no yog qhov sib txawv ntawm cov carbohydrates thiab cov rog.
