Koj puas paub dab tsi amino acids? Tib neeg yuav tsum tau txais lub zog los ntawm cov zaub mov kom muaj sia nyob thiab tswj lub cev kev loj hlob thiab kev loj hlob. Vim li cas peb yuav tsum noj cov amino acids? Amino acids yog qhov tseem ceeb rau peb lub cev. Cia peb tham txog cov haujlwm thiab cov teebmeem ntawm cov amino acids.
Cov haujlwm ntawm Amino Acids
1. Kev zom thiab nqus cov protein hauv lub cev tau ua tiav los ntawm cov amino acids: Raws li cov khoom noj tseem ceeb hauv lub cev, lub luag haujlwm ntawm cov protein hauv cov khoom noj khoom haus yog pom tseeb. Txawm li cas los xij, nws tsis tuaj yeem siv ncaj qha los ntawm tib neeg lub cev; Hloov chaw, nws yog siv tom qab tawg mus rau hauv cov amino acid molecules.
2. Ua kom muaj nitrogen tshuav nyiaj li cas: Thaum qhov zoo thiab muaj nuj nqis ntawm cov protein nyob rau hauv cov khoom noj txhua hnub yog qhov tsim nyog, tus nqi ntawm nitrogen ingested yog sib npaug rau cov nyiaj tawm hauv cov quav, zis, thiab tawv nqaij, uas yog hu ua tag nrho cov nitrogen tshuav. Hauv kev muaj tiag, nws yog qhov sib npaug ntawm kev sib txuas txuas ntxiv thiab kev sib cais ntawm cov protein thiab cov amino acids. Kev noj cov protein ntau txhua hnub ntawm ib tus neeg ib txwm yuav tsum tau khaws cia nyob rau hauv ib qho chaw. Thaum noj dheev nce lossis txo qis, lub cev tseem tuaj yeem tswj hwm tus nqi ntawm cov protein metabolism kom muaj nitrogen tshuav. Kev noj cov protein ntau dhau, dhau ntawm lub cev kev tswj hwm lub peev xwm, yuav cuam tshuam rau kev sib npaug ntawm cov txheej txheem. Txawm hais tias tsis muaj protein ntau txaus, lub cev nqaij daim tawv nqaij tseem tawg, uas ua rau muaj qhov tsis zoo ntawm nitrogen. Yog tias tsis kho tam sim ntawd, qhov no yuav kawg ua rau cov tshuaj tiv thaiv kab mob tuag.
Cov haujlwm ntawm Amino Acids
-keto acids, tsim los ntawm kev tawg ntawm cov amino acids, yog metabolized los ntawm carbohydrate lossis lipid txoj hauv kev, nyob ntawm lawv cov yam ntxwv tshwj xeeb . -keto acids tuaj yeem rov ua dua tshiab rau hauv cov amino acids tshiab, hloov mus ua suab thaj lossis rog, lossis oxidized thiab decomposed rau hauv CO2 thiab H2O hauv lub zog, tricarboxylic acid. Enzymes yog tshuaj lom neeg cov proteins (ua los ntawm cov amino acid molecules), xws li amylase, pepsin, cholinesterase, carbonic anhydrase, thiab transaminase. Nitrogenous cov tshuaj hormones yog tsim los ntawm cov proteins los yog lawv cov derivatives, xws li kev loj hlob hormone, thyroid-stimulating hormone, adrenaline, insulin, thiab enterotropic hormone. Qee cov vitamins yog tsim los ntawm cov amino acids los yog muaj nyob rau hauv ua ke nrog cov proteins. Enzymes, cov tshuaj hormones, thiab cov vitamins ua lub luag haujlwm tseem ceeb hauv kev tswj hwm lub cev kev ua haujlwm thiab ua rau cov txheej txheem metabolic.
