1.Lub plab zom mov thiab nqus cov protein hauv lub cev tau ua tiav los ntawm cov amino acids: ua thawj cov khoom noj muaj txiaj ntsig hauv lub cev, cov protein muaj lub luag haujlwm tseem ceeb hauv kev noj zaub mov, tab sis nws tsis tuaj yeem siv ncaj qha hauv lub cev. Nws yog siv los ntawm kev hloov mus rau hauv cov amino acids me me molecules.

2. ua lub luag haujlwm ntawm nitrogen sib npaug: thaum qhov ua tau zoo thiab muaj protein ntau hauv kev noj zaub mov txhua hnub tsim nyog, cov nitrogen noj yog sib npaug ntawm cov nitrogen uas tawm los ntawm cov quav, zis thiab tawv nqaij, uas hu ua tag nrho cov nyiaj tshuav. ntawm nitrogen. Qhov tseeb, nws yog qhov sib npaug ntawm kev sib txuas tas mus li thiab kev sib cais ntawm cov protein thiab amino acids. Kev noj cov protein txhua hnub ntawm tib neeg ib txwm yuav tsum tau khaws cia hauv qee qhov. Thaum noj cov zaub mov tam sim ntawd nce lossis txo qis, lub cev tseem tuaj yeem tswj cov metabolism hauv cov protein kom tswj tau nitrogen sib npaug. Kev noj cov protein ntau dhau, dhau ntawm lub cev lub peev xwm los tswj, cov txheej txheem kev tshuav nyiaj yuav raug rhuav tshem. Yog tias koj tsis noj cov protein txhua, cov nqaij protein hauv koj lub cev tseem yuav raug decomposed, thiab qhov tsis zoo nitrogen sib npaug tseem yuav tshwm sim. Yog tias koj tsis ntsuas ntsuas raws sijhawm, cov tshuaj tiv thaiv kab mob yuav tuag thaum kawg.

3. Hloov pauv mus rau qab zib lossis rog: a-keto acid uas tsim los ntawm catabolism ntawm cov amino acids tau hloov pauv raws txoj kev zom zaub mov ntawm cov piam thaj lossis rog nrog cov yam ntxwv sib txawv. a-keto acid tuaj yeem rov ua dua tshiab rau hauv cov amino acids tshiab, lossis hloov pauv mus rau hauv qab zib lossis rog, lossis nkag mus rau tri-carboxy cycle kom oxidize thiab lwj mus rau CO2 thiab H2O, thiab tso tawm lub zog.

4. Koom nrog kev tsim cov enzymes, cov tshuaj hormones, thiab qee cov vitamins: cov tshuaj lom ntawm cov enzymes yog protein (cov amino acid molecular composition), xws li amylase, pepsin, cholinesterase, carbonic anhydrase, transaminase, thiab lwm yam. cov tshuaj hormones yog cov protein lossis lawv cov txiaj ntsig, xws li kev loj hlob hormone, thyroid stimulating hormone, adrenaline, insulin, enterotropin thiab lwm yam. Qee cov vitamins tau hloov pauv los ntawm cov amino acids lossis ua ke nrog cov protein. Enzymes, cov tshuaj hormones, thiab cov vitamins ua lub luag haujlwm tseem ceeb hauv kev tswj hwm lub cev kev ua haujlwm thiab txhawb cov metabolism hauv.
