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].
