Qhov sib txawv tseem ceeb ntawm MCT thiab LCT yog tias MCT muaj cov roj carbon fatty acids nrog 6 - 12 chains, whereas LCT muaj carbon fatty acids nrog >12 carbon chains.
Triglyceride yog hom roj loj uas khaws cia los ntawm lub cev. Cov rog peb noj, xws li butter, margarine, thiab roj, feem ntau tuaj yeem pom nyob rau hauv daim ntawv ntawm triglycerides. Tsis tas li ntawd, cov calories ntau dhau, cawv, thiab qab zib hauv lub cev tig mus rau hauv triglycerides, thiab tom qab ntawd, cov no tau khaws cia hauv cov rog hauv lub cev. Muaj ob hom triglycerides: nruab nrab-chain triglycerides thiab long-chain triglycerides.
MCT (Medium Chain Triglyceride) yog dab tsi?
Lo lus MCT sawv cev rau cov saw hlau nruab nrab triglycerides. Cov no yog triglycerides nrog ob lossis peb fatty acids uas muaj aliphatic tail ntawm 6 - 12 carbon atoms. Cov tebchaw no tuaj yeem pom nyob rau hauv cov txiv maj phaub roj thiab cov txiv maj phaub roj, thiab peb tuaj yeem cais MCT ntawm lawv los ntawm kev sib faib. Ntxiv mus, peb tuaj yeem siv kev txaus siab los tsim MCT. Txawm li cas los xij, khw muag khoom MCT hmoov muaj cov carbohydrates ntxiv rau cov rog vim tias MCT no tau muab tso rau hauv cov hmoov txhuv nplej siab. Peb tuaj yeem tsim cov hmoov MCT no los ntawm kev ziab kom qhuav.
MCT tuaj yeem siv rau kev txwv calorie vim tias, raws li qee qhov kev tshawb fawb, nws tuaj yeem txo qis kev noj qab haus huv ntxiv tab sis tsis cuam tshuam rau kev noj qab haus huv. Tsis tas li ntawd, nws yog siv rau kev noj zaub mov muaj txiaj ntsig vim tias, raws li qee qhov kev ntsuas qhov hnyav ntawm cov mis nyuj los ntawm ntau hom, cov mis nyuj rog feem ntau muaj cov roj ntsha ntev ntev, thaum kwv yees li 10 - 20% ntawm fatty acid cov ntsiab lus hauv cov mis nyuj los ntawm nees, nyuj, yaj., thiab tshis yog nruab nrab saw fatty acids. Raws li qee qhov kev tshawb fawb, MCTs txhawb cov roj oxidation thiab txo cov zaub mov kom tsawg thiab raug pom zoo los ntawm qee cov neeg ncaws pob thiab cov zej zog tsim lub cev.
Daim duab 01: Medium Chain Triglyceride
Tsis tas li ntawd, MCTs tuaj yeem cuam tshuam los ntawm GI ib puag ncig mus rau lub portal system yam tsis tas yuav hloov cov saw ntev fatty acids thiab cov saw ntev ntev fatty acids. Tsis tas li ntawd, cov tshuaj no tsis xav tau cov kua tsib ntsev rau kev zom zaub mov. Yog li ntawd, peb tuaj yeem siv nws los kho cov neeg mob uas tsis muaj zaub mov tsis txaus, malabsorption, thiab qee qhov fatty acid metabolism tsis zoo. Qhov no yog vim MCTs tsis xav tau lub zog rau kev nqus, siv, thiab khaws cia.
LCT (Long Chain Triglyceride) yog dab tsi?
Lo lus LCT sawv cev rau cov saw ntev triglycerides. Cov no suav hais tias yog qhov tseem ceeb tshaj plaws ntawm kev noj zaub mov lipid. Kev zom ntawm cov tshuaj no nyob ntawm qhov sib cuam tshuam ntawm pancreatic lipase, colipase, thiab bile acids. Ntxiv mus, nws hydrolyzes triglyceride molecule rau hauv ob fatty acid molecules thiab 2-monoacyglycerol. Txhawm rau ua cov tshuaj tiv thaiv no, lipase khi rau cov roj-dej cuam tshuam ntawm cov tee dej. Cov khoom noj uas peb tuaj yeem nrhiav tau LCTs yog cov roj txiv roj, roj taum pauv, ntses, txiv ntseej, avocado, thiab nqaij. LCTs thiab 2-monoglycerol yog absorbed tom qab kev koom ua ke rau hauv micelles.
Raws li qee cov kev tshawb fawb tshawb fawb, cov protein thiab carbohydrates tuaj yeem muab txog 17 kJ g-1 lub zog, thaum LCTs tuaj yeem muab txog 38 kJ g -1. Yog li ntawd, cov fatty acids no yog siv los tsim lub zog hauv cell mitochondria thiab peroxisomes.
Qhov txawv ntawm MCT thiab LCT yog dab tsi?
MCT thiab LCT yog cov txiaj ntsig ntawm triglycerides. MCT stands rau nruab nrab-chain triglycerides whereas LCT stands rau long-chain triglycerides. Qhov sib txawv tseem ceeb ntawm MCT thiab LCT yog tias MCT muaj carbon fatty acids nrog 6 - 12 chains, whereas LCT muaj carbon fatty acids nrog >12 carbon chains.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm MCT thiab LCT hauv daim ntawv teev npe rau kev sib piv ntawm ib sab.
Summary – MCT vs LCT
Lub sij hawm MCT sawv cev rau nruab nrab cov saw triglycerides thaum lub sij hawm LCT sawv cev rau cov saw ntev triglycerides. Qhov sib txawv tseem ceeb ntawm MCT thiab LCT yog tias MCT muaj carbon fatty acids nrog 6 - 12 chains, whereas LCT muaj carbon fatty acids nrog >12 carbon chains.
