Protein catabolism Protein catabolism Nyob rau hauv molecular biology, protein catabolism yog tawg ntawm cov proteins rau hauv me peptides thiab thaum kawg rau hauv cov amino acids. Protein catabolism yog lub luag haujlwm tseem ceeb ntawm kev zom zaub mov. Protein catabolism feem ntau pib nrog pepsin, uas hloov cov proteins rau hauv polypeptides. Cov polypeptides no yog tom qab ntawd degraded ntxiv. https://en.wikipedia.org › wiki › Protein_catabolism
Y Protein catabolism - Wikipedia
is ib feem tseem ceeb ntawm kev hloov pauv ntawm tes. Thaum cov cytosolic proteins xws li kev taw qhia lossis cov qauv peptides tsis xav tau lawm, lawv yuav tsum tau tawg hauv lysosomes los tsim cov proteins tshiab uas tuaj yeem ua tiav cov haujlwm tsim nyog metabolic.
YYuav ua li cas cov proteins catabolized?
Nyob rau hauv molecular biology, protein catabolism yog kev tawg ntawm cov proteins rau hauv me peptides thiab thaum kawg rau hauv cov amino acids. Protein catabolism yog lub luag haujlwm tseem ceeb ntawm kev zom zaub mov. Protein catabolism feem ntau pib nrog pepsin, uas hloov cov proteins rau hauv polypeptides. Cov polypeptides no ces degraded ntxiv.
Dab tsi ua rau cov protein catabolism?
Accelerated protein catabolism nyob rau hauv uremia tshwm sim nyob rau hauv cov tsiaj thiab cov neeg mob mob (ARF) thiab mob raum tsis ua hauj lwm (CRF). Cov ua tau muaj xws li tawm tsam rau ob qho tib si insulin-induced inhibition ntawm protein-degradation thiab insulin-induced stimulation ntawm protein synthesis.
Lub hom phiaj ntawm cov protein yog dab tsimetabolism?
Function. Protein metabolism muaj ib lub voj voog ntawm kev rhuav tshem cov proteins, tsim cov tshiab thiab tshem tawm cov khoom pov tseg nitrogenous uas tshwm sim los ntawm cov tshuaj tiv thaiv no. Tus nqi ntawm cov protein xav tau los sib npaug ntawm lub voj voog no hloov pauv thoob plaws ib tus neeg lub neej.
Catabolized amino acids li cas?
Catabolism ntawm cov amino acids koom nrog tshem tawm cov amino pawg, ua raws li kev tawg ntawm cov pob txha ua carbon. Hauv kev sib piv rau lwm cov amino acids, BCAAs yog metabolized feem ntau los ntawm cov ntaub so ntswg peripheral (tshwj xeeb yog cov leeg nqaij), tsis yog los ntawm lub siab [11].

Vim li cas kev taw qhia tseem ceeb hauv cov qauv ntawm cov protein?
Vim tias cov qauv ntawm cov amino acids, cov saw hlau polypeptide muaj kev taw qhia, txhais tau tias nws muaj ob qhov kawg uas yog tshuaj sib txawv ntawm ib leeg. … Yuav kom kawm paub tias kev sib cuam tshuam ntawm cov amino acids ua rau cov protein ntau npaum li cas rau hauv nws qhov kev paub tab, kuv xav kom cov yeeb yaj kiab ntawm kev txiav txim ntawm cov qauv protein.
Vim li cas cov zaub mov muaj protein tsawg tsawg carb noj?
Cov protein ntau, cov zaub mov tsis muaj carb yuav txhawb kev poob phaus, khaws cov leeg nqaij, txhim kho ntshav qab zib, txo koj txoj kev pheej hmoo ntawm kab mob plawv, thiab txhim kho pob txha noj qab haus huv. Vim li cas cov zaub mov muaj protein ntau tsawg ua haujlwm?
Puas yog qabzib tsuas yog molecule uas tuaj yeem catabolized?
Puas yog cov piam thaj tib yam uas tuaj yeem ua rau catabolized thaum lub sijhawm ua pa ntawm tes? Glucose yog lub ntsiab molecule rau kev ua pa cellular respiration (los ntawm glycolysis thiab ces kreb lub voj voog) muab ATP. Lwm cov molecules suav nrog cov khoom ntawm glycolysis thiab kreb lub voj voog tshwj xeeb tshaj yog acetyl-coenzyme A (acetyl CoA).
Yuav ua li cas rau cov molecule ntawm cov protein thaum lub sij hawm zom mov?
Ib zaug ib qho khoom noj protein nkag mus rau hauv koj lub plab, hydrochloric acid thiab enzymes hu ua proteases zom nws mus rau hauv cov saw me me ntawm cov amino acids. Amino acids koom ua ke los ntawm peptides, uas tawg los ntawm proteases.
Cov khoom lag luam puas tuaj yeem kho tus kheej vim li cas lossis vim li cas ho tsis?
Cov khoom lag luam yuam kev feem ntau yog kho tus kheej, txhais tau tias qhov ua yuam kev hauv qhov kawg cov khoom muag Yuav muaj qhov cuam tshuam rov qab rau cov nyiaj tau los hauv lub sijhawm nyiaj txiag tom ntej. Yog li dhau ob xyoos, tag nrho cov nyiaj tau los yog qhov tseeb vim qhov ua yuam kev sib cuam tshuam.
