Kev zom cov protein los ntawm kev noj zaub mov ua rau cov amino acids ntau dhau, uas yuav tsum tau muab tso tawm kom nyab xeeb. Nyob rau hauv daim siab cov amino acids yog deaminated los tsim ammonia. Ammonia yog tshuaj lom thiab yog li nws tam sim ntawd hloov mus rau urea kom muaj kev nyab xeeb excretion.
Dab tsi yog qhov tawg ntawm cov amino acids ntau dhau hu ua?
Cov txheej txheem metabolic tseem ceeb no hu ua deamination.
Yuav ua li cas rau cov amino acids seem?
Thaum koj noj cov protein, lub cev zom lawv mus rau hauv cov amino acids. Ammonia yog tsim los ntawm cov amino acids tshuav, thiab nws yuav tsum raug tshem tawm ntawm lub cev. Lub siab tsim ntau yam tshuaj (enzymes) uas hloov ammonia rau hauv daim ntawv hu ua urea, uas lub cev tuaj yeem tshem tawm hauv cov zis.
Cov kev mob tshwm sim ntawm ntau cov amino acids yog dab tsi?
Thaum koj lub cev muaj cov amino acids ntau dhau lawm, cov teebmeem hauv qab no tuaj yeem tshwm sim:
- mob plab hnyuv, xws li tsam plab.
- mob plab.
- Zoo.
- Muaj kev pheej hmoo ntawm gout (tsim cov uric acid hauv lub cev, ua rau mob pob qij txha)
- Kev poob qis hauv ntshav siab.
- Kev hloov pauv ntawm kev noj mov.
Yuav ua li cas cov amino acids luv lub neej?
Feem ntau ntawm cov khoom noj amino acid luv luv nrog kev hwm rau 'tsis muaj AA' noj, tshwj tsis yog glutamate, tyrosine thiab tryptophan(daim duab 6; cov khoom siv hluav taws xob ntxiv, rooj S18). Ntawm cov uas luv luv lifespan, plaub muaj teeb meem tshwj xeeb: phenylalanine, serine, threonine thiab methionine (daim duab 6).

Qhov twg deaminates ntau cov amino acids?
Kev daws: Deamination thiab urea tsim yog ib qho haujlwm tseem ceeb ntawm siab. Deamination ntawm amino acids feem ntau yog ua los ntawm daim siab (sib cais ntawm cov amino pawg ntawm cov amino acid thiab nws hloov mus rau ammonia). Kev npaj ntawm urea los ntawm cov amino acids yog ua los ntawm lub siab .
Yuav ua li cas cov proteins tsim los ntawm cov amino acids?
Proteins yog tsim nyob rau hauv cov tshuaj tiv thaiv condensation thaum cov amino acid molecules koom ua ke thiab cov dej molecule raug tshem tawm. Daim ntawv cog lus tshiab tsim nyob rau hauv cov protein molecules uas cov amino acids tau koom nrog (-CONH) yog hu ua amide link lossis peptide link .
Puas yog cov concentrated acids muaj zog acids?
A cov kua qaub uas muaj zog yog ib qho kev sib cais tag nrho los tsim H3O + ions hauv cov tshuaj aqueous, qhov twg raws li cov kua qaub tsis muaj zog tsuas yog ua qee yam. Cov kua qaub concentrated, ntawm qhov tod tes, yog ib qho uas muaj qhov siab heev ntawm H3O + ions hauv cov kua dej .
Puas yog ram ntau dhau lawm?
Muaj ntau tus ram yuav tsis ua rau koj qhov kev ua tau zoo. Yog tias muaj dab tsi, nws yuav ua rau muaj kev ua tau zoo vim nws yuav tsis tau nkag mus rau HDD / SSD qeeb li ntau zaus. Txawm hais tias muaj nplooj ntawv loj heev yuav ua rau kev ua haujlwm tsis zoo .
Puas dhau mus ntev dhau lawm?
Daim Ntawv Nkag Mus Rau Lub Sij Hawm Ntev (LTVP) yog rau tus txij nkawm-txoj cai, cov menyuam yaus lossis cov menyuam xiam oob khab ntawm Daim Ntawv Ua Haujlwm lossis tus tuav S Pass. Cov neeg tuav hla dhau $12,000 kuj tuaj yeem tau txais daim ntawv hla tebchaws rau niam txiv.
