Qhov sib txawv tseem ceeb ntawm casein thiab lactose yog tias casein yog tsev neeg ntawm phosphoproteins pom hauv cov mis nyuj thaum lactose yog disaccharide (qab zib) pom hauv mis.
Lactose yog ib qho disaccharide ua los ntawm ob qho yooj yim suab thaj: qabzib thiab galactose. Nws yog lub ntsiab carbohydrate hauv cov khoom noj siv mis. Nws kuj muaj nyob rau hauv cov kua mis. Casein yog cov protein tseem ceeb tshaj plaws hauv cov mis nyuj. Casein muaj peev xwm muab tag nrho cov amino acids tseem ceeb. Yog li, ob qho tib si lactose thiab casein yog cov khoom ntawm cov mis nyuj uas muaj txiaj ntsig zoo. Qee tus neeg tuaj yeem ua rau tsis haum rau lactose thiab casein; lawv yuav tsum tsis txhob noj zaub mov uas muaj ob yam khoom no.
Casin yog dab tsi?
Casein yog cov kua mis muaj protein ntau hauv cov khoom siv mis nyuj. Nws yog cov khoom dawb uas tsis qab thiab tsis muaj ntxhiab. Nws yog cov protein ua tiav uas tuaj yeem muab tag nrho cov amino acids tseem ceeb uas peb xav tau rau kev loj hlob thiab kho. Cov tshuaj formula ntawm casein yog C81H125N22O39 P, thiab qhov hnyav molecular yog 2062 g / mol.
Daim duab 01: Casein
Casein yog cov protein uas zom qeeb qeeb uas qhia tau tias qhov nqus tau qeeb ntawm lub plab. Ntxiv mus, casein tsis zoo soluble hauv dej. Yog li ntawd, nws yog hydrophobic. Casein muaj txiaj ntsig zoo rau cov leeg nqaij vim nws muab cov leucine ntau, uas pib cov leeg nqaij protein synthesis. Qee tus neeg tuaj yeem ua rau tsis haum rau casein, qhia cov tsos mob xws li roj, plab hnyuv thiab raws plab.
YLactose yog dab tsi?
Lactose yog hom qab zib uas muaj nyob hauv cov mis nyuj ntawm cov tsiaj. Qhov tseeb, nws yog ib qho disaccharide tsim los ntawm galactose thiab qabzib subunits. Cov tshuaj formula ntawm lactose yog C12H22O11 Cov khoom hnyav ntawm lactose yog 342.3 g / mol. Lactose yog dawb, dej-soluble, tsis-hygroscopic khoom nrog ib tug me ntsis qab zib saj.
Daim duab 02: Lactose
Y Hauv tib neeg, lactase yog cov enzyme uas zom cov lactose thaum lub plab zom mov. Lactose intolerance yog ib qho teeb meem digestive uas hais txog qhov tsis muaj peev xwm zom cov lactose hauv cov khoom noj siv mis. Bloating, raws plab, roj thiab mob plab yog cov tsos mob ntawm lactose intolerance.
Dab tsi zoo sib xws ntawm Casein thiab Lactose?
- Ob leeg casein thiab lactose yog ob yam khoom pom hauv cov mis nyuj.
- Qee tus neeg tuaj yeem ua rau tsis haum rau lactose thiab casein.
- Yog li ntawd, ob qho tib si tuaj yeem ua rau muaj cov tsos mob xws li roj, plab hnyuv thiab raws plab.
Qhov txawv ntawm Casein thiab Lactose yog dab tsi?
Casein yog mis nyuj protein, thaum lactose yog mis nyuj qab zib (carbohydrate). Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm casein thiab lactose. Tsis tas li ntawd, casein yog dej-insoluble thaum lactose yog dej-soluble. Yog li, qhov no kuj yog qhov sib txawv tseem ceeb ntawm casein thiab lactose.
Tsis tas li ntawd, casein yog cov protein uas zom qeeb qeeb thaum lactose yog cov piam thaj sai sai. Trypsin digests casein thaum lactase digests lactose. Ntxiv rau cov no, casein tsis qab qab thaum lactose muaj qab zib me ntsis.
Cov hauv qab no infographic tabulates qhov sib txawv ntawm casein thiab lactose kom ntxaws.
Summary – Casein vs Lactose
Casein thiab lactose yog ob yam khoom xyaw ntawm mis nyuj. Casein yog ib qho protein uas nplua nuj nyob hauv cov amino acids tseem ceeb. Lactose, ntawm qhov tod tes, yog ib qho disaccharide uas muaj ob lub suab thaj molecules. Trypsin yog cov enzyme uas zom cov casein thaum lactase yog cov enzyme uas zom cov lactose. Casein yog dej-insoluble thaum lactose yog dej-soluble. Casein muaj qhov hnyav molecular piv rau lactose. Ntxiv mus, casein muaj phosphorus, tsis zoo li lactose. Yog li, qhov no qhia txog qhov sib txawv ntawm casein thiab lactose.
