Qhov sib txawv tseem ceeb ntawm cov kua tsib ntsev thiab cov kua tsib xim yog cov kua tsib ntsev yog cov khoom tseem ceeb ntawm cov kua tsib ua los ntawm kev sib txuas ntawm cov kua tsib nrog cov poov tshuaj ion lossis sodium ion, thaum cov kua tsib pigments yog cov khoom tseem ceeb ntawm cov kua tsib ua los ntawm cov kua tsib. decomposition ntawm lub nplhaib porphyrin.
Bile yog cov kua dej ua thiab tso tawm los ntawm lub siab thiab khaws cia rau hauv lub gallbladder. Nws nquag pab nrog kev zom zaub mov. Cov kua tsib zom cov rog mus rau hauv fatty acids. Cov fatty acids no tuaj yeem coj mus rau hauv lub cev los ntawm kev zom zaub mov. Cov kua tsib muaj 98% dej, 0.7% kua tsib ntsev, 0.2% bilirubin (bile pigments), 0.51% rog, thiab 200 meq/l ntawm inorganic ntsev. Yog li ntawd, cov kua tsib ntsev thiab cov kua tsib xim yog ob yam tseem ceeb ntawm cov kua tsib.
Nyob hauv qab ntsev yog dab tsi?
Bile ntsev yog ib qho tseem ceeb ntawm cov kua tsib ua los ntawm kev sib txuas ntawm cov kua tsib nrog cov poov tshuaj ions thiab sodium ions. Cov kua tsib kua qaub yog tsim los ntawm cov kab mob hepatocyte hauv daim siab. Cov kua tsib kua qaub no yog muab los ntawm cov cholesterol. Bile ntsev zoo ib yam li cov kua tsib acids. Cov kua tsib ntsev yog tsim thaum cov kua tsib acids khi rau cov molecules ntawm poov tshuaj los yog sodium. Tag nrho cov kua tsib ntsev muaj cov roj (cholesterol) los ntawm cov kua tsib kua qaub ua ke rau cov poov tshuaj lossis sodium ions. Qee cov kua tsib ntsev yog hloov los ntawm cov kab mob hauv plab los ntawm kev tshem tawm cov atoms. Qhov no tsim dab tsi yog hu ua cov kua tsib ntsev thib ob. Ntxiv mus, lwm cov kua tsib ntsev conjugate nrog amino acids xws li taurine thiab glycine los tsim conjugated bile ntsev.
Daim duab 01: Npua ntsev
Lub luag haujlwm tseem ceeb ntawm cov kua tsib thiab cov kua tsib ntsev hauv lub cev yog pab zom zaub mov los ntawm kev zom cov rog, pab nqus cov vitamins muaj roj, thiab tshem tawm cov khoom pov tseg. Tsis tas li ntawd, yog tias lub cev tsis tsim cov kua tsib txaus vim muaj cov kab mob xws li lub zais zis tshem tawm, ib tus neeg yuav muaj teeb meem xws li raws plab, muaj roj, roj tsw qab, mob plab, mob plab zom mov, poob phaus, thiab cov quav xim daj ntseg.
Pigments yog dab tsi?
Bile pigments yog ib qho tseem ceeb ntawm cov kua tsib ua los ntawm decomposition ntawm lub nplhaib porphyrin. Lawv tseem hu ua bilins lossis biplanes. Bile pigments yog cov xim lom neeg hauv ntau yam kab mob. Lawv yog cov metabolic los ntawm cov khoom ntawm qee yam porphyrins. Feem ntau, cov kua tsib xim muaj nyob rau hauv ntau yam kab mob, nrog rau cov tsiaj nyeg, vertebrates, invertebrates, liab algae, ntsuab nroj tsuag, thiab cyanobacteria.
Daim duab 02: Bile Pigments
Nyob rau hauv tib neeg, lawv yog cov xim sib xyaw thiab zom cov khoom ntawm cov ntshav pigment hemoglobin uas tau tawm hauv cov kua tsib. Cov kua tsib tseem ceeb tshaj plaws yog bilirubin, uas yog xim txiv kab ntxwv lossis daj, thiab biliverdin (daim ntawv oxidized), uas yog xim ntsuab. Tsis tas li ntawd, sib xyaw nrog cov khoom hauv plab hnyuv, cov kua tsib xim muab xim xim av rau cov quav (urobilinogen).
Dab tsi yog qhov zoo sib xws ntawm cov kua ntsev thiab kua tsib cov xim?
- kua ntsev thiab kua tsib xim yog ob lub ntsiab ntawm cov kua tsib.
- Ob lub ntsiab lus yog zais los ntawm lub siab thiab dhau mus rau lub gallbladder.
- Lawv ua lub luag haujlwm tseem ceeb hauv tib neeg lub cev.
Dab tsi yog qhov txawv ntawm cov kua tsib ntsev thiab kua tsib cov xim?
Bile ntsev yog ib qho tseem ceeb ntawm cov kua tsib ua los ntawm kev sib txuas ntawm cov kua tsib acids nrog cov poov tshuaj ion lossis sodium ion, thaum cov kua tsib xim yog cov khoom tseem ceeb ntawm cov kua tsib los ntawm kev decomposition ntawm lub nplhaib porphyrin. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm cov kua tsib ntsev thiab kua tsib pigments. Tsis tas li ntawd, cov kua tsib muaj 0.7% ntawm cov kua tsib ntsev thiab 0.2% ntawm cov kua tsib xim.
Cov ntawv qhia hauv qab no nthuav tawm qhov sib txawv ntawm cov kua tsib ntsev thiab cov kua tsib xim hauv daim ntawv qhia rau kev sib piv ntawm ib sab.
Summary – Bile S alts vs Bile Pigments
Bile pab txhawb kev zom zaub mov thiab muaj dej, kua tsib ntsev, bilirubin (bile pigments), rog, thiab ntsev inorganic. Bile ntsev yog ib qho tseem ceeb ntawm cov kua tsib ua los ntawm kev sib txuas ntawm cov kua tsib acids nrog cov poov tshuaj ion lossis sodium ion, thaum cov kua tsib pigments yog cov khoom tseem ceeb ntawm cov kua tsib uas ua los ntawm decomposition ntawm lub nplhaib porphyrin. Yog li, qhov no yog qhov txawv ntawm cov kua tsib ntsev thiab cov kua tsib xim.
