Feem ntau hauv tib neeg, kev deamination tshwm sim thaum ntau tshaj ntawm cov protein tau noj, ua rau tshem tawm cov pab pawg amine, uas tom qab ntawd hloov mus rau hauv ammonia thiab tshem tawm los ntawm kev tso zis. Cov txheej txheem deamination no tso cai rau lub cev hloov cov amino acids ntau dhau rau hauv cov khoom siv tau.
Yuav ua li cas rau cov khoom ntawm cov txheej txheem deamination?
Urea yog tsim Thaum Deamination thiab tshem tawm raws li cov khoom pov tseg. Cov ammonia tso tawm thaum lub sij hawm deamination raug tshem tawm ntawm cov ntshav yuav luag tag nrho los ntawm kev hloov mus rau hauv urea hauv daim siab. Qhov no tshwm sim los ntawm lwm cov txheej txheem metabolic hu ua lub voj voog urea (saib daim duab 2.11.
Vim li cas kev hloov pauv thiab kev txiav txim siab tseem ceeb?
Kev hloov pauv yog ntawm tseem ceeb hauv cov amino acid metabolism, muab txoj hauv kev rau catabolism ntawm feem ntau cov amino acids nrog rau kev sib txuas ntawm cov amino acids uas muaj qhov chaw ntawm cov amino acids. oxo-acid uas tsis yog los ntawm cov amino acid nws tus kheej-cov amino acids tsis tseem ceeb.
Qhov tseem ceeb ntawm oxidative deamination yog dab tsi?
Oxidative deamination yog ib kauj ruam tseem ceeb hauv catabolism ntawm cov amino acids, tsim cov tshuaj metabolizable ntau dua ntawm cov amino acid, thiab tseem tsim cov ammonia ua cov khoom muaj tshuaj lom. Cov ammonia tsim nyob rau hauv cov txheej txheem no tuaj yeem ua rau neutralized rau hauv urea ntawm lub voj voog urea.
Ib yam piv txwv ntawm deamination yog dab tsi?
Deamination hloov nitrogen los ntawm cov amino acid rau hauv ammonia, uas yog hloov los ntawm lub siab mus rau hauv urea hauv lub voj voog urea. Qhov piv txwv no yog los ntawm Wikipedia thiab yuav rov qab siv tau raws li daim ntawv tso cai CC BY-SA. Kev hloov pauv ntau tshaj plaws yog deamination ntawm cytosine rau uracil.
