Qhov sib txawv tseem ceeb ntawm kev hloov pauv thiab kev deamination yog qhov hloov pauv yog hloov ntawm ib pawg amino rau keto whereas deamination yog tshem tawm ntawm pawg amino.
Kev hloov pauv thiab deamination yog ob hom tshuaj tiv thaiv uas qhov kev hloov ntawm cov amino pawg hauv cov organic molecules tshwm sim. Cov txheej txheem no tshwm sim hauv cov amino acid molecules thiab tshwm sim feem ntau yog tsim los yog degradation txoj kev ntawm amino acids.
Kev hloov pauv yog dab tsi?
Kev hloov pauv yog tshuaj lom neeg uas hloov pauv ntawm pawg amino rau ketoacid tshwm sim. Cov txheej txheem no tsim cov amino acids tshiab. Ntxiv mus, cov txheej txheem no yog lub luag haujlwm rau deamination ntawm feem ntau cov amino acids thiab. Nws yog vim hais tias cov amino pawg ntawm ib tug amino acid dhau qhov kev hloov no. Tsis tas li, cov txheej txheem no ua rau kev hloov pauv ntawm cov amino acids tseem ceeb rau hauv cov amino acids tsis tseem ceeb.
Daim duab 1: Kev Sib Tham Sib Tham
Hauv cov kab mob lom neeg, kev hloov pauv tshwm sim nyob rau hauv muaj cov enzymes xws li transaminases thiab aminotransferases. Ntawm no, cov compound alpha-ketoglutarate ua raws li cov amino pawg neeg lees paub thiab nws tsim glutamate. Li no, cov amino acid tshiab uas tsim muaj glutamate. Lwm yam khoom yog alpha-keto acid.
Deamination yog dab tsi?
Deamination yog cov tshuaj tiv thaiv uas cuam tshuam nrog kev tshem tawm cov amino acid pawg los ntawm cov organic compound. Cov tshuaj tiv thaiv no yuav tsum muaj cov deaminases. Hauv lwm lo lus, deaminases catalyze cov txheej txheem deamination.
Daim duab 2: Deamination ntawm Cytosine
Feem ntau, qhov tshuaj tiv thaiv no tshwm sim hauv daim siab ntawm peb lub cev. Txawm li cas los xij, deamination ntawm glutamate tuaj yeem tshwm sim hauv ob lub raum thiab. Qhov tseem ceeb ntawm kev siv cov tshuaj tiv thaiv no yog tias nws rhuav tshem cov amino acids los tsim lub zog. Ntawm no, cov txheej txheem tshem tawm cov nitrogenous ib feem ntawm cov amino acid los ntawm cov molecule thiab hloov mus rau hauv ammonia. Tsis tas li ntawd, qhov uas tsis yog-nitrogenous tau rov ua dua thiab oxidation los tsim lub zog.
Qhov txawv ntawm Kev Hloov Pauv thiab Kev Deamination yog dab tsi?
Qhov sib txawv tseem ceeb ntawm kev hloov pauv thiab kev deamination yog qhov hloov pauv yog hloov ntawm ib pawg amino rau keto acid thaum qhov deamination yog tshem tawm cov amino pawg. Ntxiv mus, transamination muaj ob lub molecules: amino acid thiab ketoacid, thaum deamination muaj ib tug molecule; ib qho amino acid.
Dhau li ntawm qhov sib txawv saum toj no, qhov sib txawv tseem ceeb ntawm kev hloov pauv thiab kev deamination yog qhov kev hloov pauv cuam tshuam nrog kev hloov pauv ntawm cov amino acids tseem ceeb rau hauv cov amino acids tsis tseem ceeb thaum lub deamination cuam tshuam nrog kev tawg ntawm cov amino acids los tsim lub zog.
Summary – Transamination vs Deamination
Hauv luv luv, transamination thiab deamination yog ob txheej txheem uas muaj cov amino acids. Qhov sib txawv tseem ceeb ntawm transamination thiab deamination yog qhov kev hloov pauv yog hloov ntawm ib pawg amino mus rau keto acid thaum lub deamination yog tshem tawm ntawm ib pawg amino.
