tag nrho peptides thiab protein muab qhov kev sim zoo . Histidine tsuas yog cov amino acid xwb uas muab biuret kuaj pom zoo.
Yuav ua li cas cov proteins muab qhov kev kuaj biuret zoo?
Txhua cov proteins thiab peptides muab qhov zoo. Tsuas yog amino acid, Histidine, muab qhov txiaj ntsig zoo. Tsis muaj kev hloov xim. Tsis tas li ntawd, txhawm rau xyuas kom meej tias cov qauv ntsuas yog alkaline, ntxiv ob peb tee ntawm 5% sodium hydroxide tov rau txhua lub raj kuaj.
Puas kuaj biuret kuaj rau cov protein?
Tus biuret cov tshuaj tiv thaiv tuaj yeem siv los ntsuas qhov concentration ntawm cov proteins vim tias peptide bonds tshwm sim nrog tib zaus ib qho amino acid hauv peptide. … Qhov kev sim no muaj npe vim tias nws kuj muab cov tshuaj tiv thaiv zoo rau peptide zoo li daim ntawv cog lus hauv biuret molecule.
Yuav ua li cas protein tsis muab tshuaj biuret?
Vim tias tsis muaj amide linkage hauv carbohydrates, lawv tsis muab qhov kev sim no. B. Cov saw hlau polypeptide yog cov saw hlau ntawm cov amino acids txuas ua ke los ntawm peptide bonds. Nws tseem tuaj yeem txhais tau tias yog kev txiav txim siab ntawm mRNA rau hauv cov protein.
YYuav ua li cas biuret teb nrog cov protein?
Proteins tuaj yeem kuaj pom los ntawm kev siv Biuret kuaj. Tshwj xeeb, peptide bonds (C-N bonds) hauv cov proteins complex nrog Cu2+ hauv Biuret reagent thiab tsim xim violet. A Cu2+ yuav tsum complex nrog plaub mus rau rau peptide bonds los tsim cov xim; yog li ntawd, dawb amino acids uatsis pom zoo teb.

Cov khoom xyaw twg hauv qab no ua cov tshuaj tsw qab hauv cov tshuaj txhuam hniav?
Sodium lauryl sulfate (SLS) yog surfactant feem ntau siv. YPuas yog tshuaj txhuam hniav puas yog surfactant? Surfactants. Ntau, txawm tias tsis yog tag nrho, tshuaj txhuam hniav muaj sodium lauryl sulfate (SLS) lossis lwm yam surfactants (detergents).
Yuav ua li cas hloov cov proteins?
Protein synthesis yog ua tiav los ntawm tus txheej txheem hu ua translation. Tom qab DNA tau sau rau hauv tus xa xov RNA (mRNA) molecule thaum lub sijhawm sau ntawv, mRNA yuav tsum tau muab txhais ua cov protein. Hauv kev txhais lus, mRNA nrog rau kev hloov RNA (tRNA) thiab ribosomes ua haujlwm ua ke los tsim cov protein.
Yuav ua li cas cov proteins secretory tsim?
Secretory proteins yog synthesized los ntawm ribosomes txuas rau cisternae ntawm endoplasmic reticulumthiab translocated mus rau lub lumen ntawm endoplasmic reticulum. cov proteins uas zais cia nyob qhov twg? Yog li, los ntawm lub sijhawm cov protein ua tiav nws daim ntawv kawg, nws tau muab tso rau hauv daim nyias nyias (Daim duab 1).
Yuav ua li cas txhaj tshuaj tiv thaiv kab mob hauv qab no niaj hnub muab tshuaj intramuscularly?
Nyob, cov tshuaj tiv thaiv tsis zoo (piv txwv li, MMR, varicella, daj kub taub hau) thiab qee yam tshuaj tiv thaiv tsis ua haujlwm (xws li meningococcal polysaccharide) tau pom zoo los ntawm cov tuam txhab ua haujlwm los ntawm subcutaneous. txhaj tshuaj.
Cov tshuaj twg yog cov tshuaj uas tsis yog tshuaj tiv thaiv inflammatory analgesic?
Txhua yam koj yuav tsum paub txog NSAIDs. Nonsteroidal anti-inflammatory tshuaj (NSAIDs) yog cov tshuaj uas txo qis lossis txo qhov mob. Cov piv txwv nrov tshaj plaws ntawm cov tshuaj hauv pawg no yog aspirin thiab ibuprofen. NSAIDs tuaj nyob rau hauv lub ntsiab lus dav ntawm non-opioid analgesics.
