Cov vitamins tau muab faib ua rog-soluble (A, D, E, K) thiab dej-soluble (B- complex, C) raws li solubility- qhov tseem ceeb no sib txawv ntawm lawv qhov nqus, khaws cia, kev nyab xeeb, thiab kev ua haujlwm, muab cov lus qhia tseem ceeb rau kev npaj noj haus.
Solubility & Absorption: Rog-Dependent vs Dej-Soluble
Rog- cov vitamins soluble tsuas yog yaj hauv cov rog thiab cov kuab tshuaj organic xwb, xav tau cov kua tsib kua qaub los ua cov rog rau txoj hnyuv nqus, nrog kev thauj mus los ntawm lipoproteins. Kev noj zaub mov muaj roj ncaj qha cuam tshuam rau lawv qhov nqus tau zoo. Hauv qhov sib piv, dej- cov vitamins soluble yaj hauv dej, ua kom nqus tau sai los ntawm cov hnyuv mucosa yam tsis muaj kev pabcuam rog, thiab xa mus sai sai rau cov ntaub so ntswg ntawm cov hlab ntsha.
Cia & Metabolism: Ntev- Lub Sij Hawm Sib Nqus vs. Tam Sim No Excretion
Rog- cov vitamins uas muaj kuab lom feem ntau hauv daim siab thiab cov ntaub so ntswg adipose, khaws cia rau lub lis piam mus rau hli, yog li kev noj tshuaj txhua hnub tsis tsim nyog. Dej- cov vitamins soluble tsis tshua khaws cia; Cov nyiaj ntau dhau raug tso tawm los ntawm ob lub raum hauv cov zis, xav kom noj txhua hnub kom tsis txhob muaj qhov tsis txaus.
Kev Nyab Xeeb Profile: Ntau dua Toxicity Risk vs Tsawg Risk
Rog- cov vitamins uas muaj kuab lom ua rau muaj kev phom sij ntau dua vim muaj kev txuam nrog. Kev noj ntau dhau -tshwj xeeb ntawm A thiab D- tuaj yeem ua rau daim siab puas lossis hypercalcemia. Dej- cov vitamins feem ntau muaj kev nyab xeeb; toxicity tsuas yog tshwm sim nrog lub sijhawm ntev ultra- koob tshuaj B6 siab (muaj peev xwm ua rau neurotoxicity), thaum noj zaub mov ntau dhau yog tawm mus.
Khoom noj khoom haus & Kev ruaj ntseg
Rog- cov vitamins soluble muaj ntau nyob rau hauv cov khoom noj muaj roj ntau (tsiaj siab, roj, qe qe, txiv ntseej), ruaj khov rau cua sov thiab oxygen tab sis rhiab rau UV teeb. Dej- cov vitamins muaj nyob hauv cov txiv hmab txiv ntoo tshiab, zaub, nplej, thiab legumes, tab sis yog cov cua sov/oxygen-sensitive-yuav poob thaum boiling/frying. ceev do-frying los yog txias hnav khaub ncaws yog pom zoo kom khaws cia.
Physiological Functions
Rog- cov vitamins soluble tswj lub cev ntev - cov txheej txheem ntawm lub cev: A txhawb kev pom thiab kev tiv thaiv kab mob, D pab txhawb kev nqus calcium, E ua raws li antioxidant, thiab K ua kom cov ntshav khov. Dej- cov vitamins soluble tsom rau lub zog metabolism thiab cov kev xav tau tam sim: B- pab cuam nyuaj rau carbohydrate / fat / protein metabolism, thaum C muaj cov txiaj ntsig antioxidant, txhawb nqa collagen synthesis, thiab txhawb kev nqus hlau.
Hauv cov ntsiab lus, solubility tsav qhov sib txawv tseem ceeb ntawm ob pawg. Rog- cov vitamins soluble yuav tsum tau ceev faj ntxiv kom tsis txhob muaj tshuaj lom, thaum dej- cov vitamins soluble xav tau kev noj haus thiab ua noj kom zoo. Kev noj zaub mov kom zoo nrog ob qho tib si ua kom cov khoom noj muaj txiaj ntsig zoo rau kev noj qab haus huv.
