Lub siab yog qhov chaw tseem ceeb rau kev hloov pauv. Tag nrho cov amino acids tuaj yeem hloov pauv tsuas yog lysine, threonine, proline thiab hydroxy proline. Txhua qhov kev hloov pauv hloov pauv hloov pauv tau.
Kev hloov pauv hauv lub cev li cas?
Lub siab yog qhov chaw tseem ceeb ntawm cov amino acid metabolism, tab sis lwm cov ntaub so ntswg, xws li lub raum, cov hnyuv me, cov leeg, thiab cov ntaub so ntswg adipose, koom nrog. Feem ntau, thawj kauj ruam hauv kev tawg ntawm cov amino acids yog kev sib cais ntawm cov amino pawg los ntawm cov pob txha pob txha, feem ntau yog los ntawm cov tshuaj tiv thaiv transamination.
Puas hloov pauv tshwm sim hauv cytosol lossis mitochondria?
Valine, leucine, thiab isoleucine degradation
Valine, leucine, thiab isoleucine yog cov saw hlau amino acids (BCAAs) thiab lawv txoj kev degradation feem ntau nyob hauv cheeb tsam mitochondria tsuas yog thawj qhov kev hloov pauv. kauj ruam, uas tshwm sim hauv cytoplasm (8).
Puas hloov pauv tshwm sim hauv cytosol?
Alpha-ketoglutarate qee zaum sau ua 2-oxoglutarate. Muaj ob hom kev sib txawv ntawm cov enzyme no (qhov sib txawv ntawm cov amino acid sib txawv), ib qho nyob hauv mitochondrion thiab ib qho hauv cytosol (soluble cytoplasm).
Kev hloov pauv ntawm alanine tshwm sim nyob qhov twg?
Lub siab siv cov alanine thiab hloov nws rov qab rau hauv pyruvate los ntawm kev hloov pauv. Cov pyruvate tuaj yeem siv rau gluconeogenesis thiabcov amino pawg nws thiaj li tshwm sim li urea. Kev thauj mus los no yog hu ua lub voj voog alanine.
