Cov khoom muaj zog thiab ruaj khov

Cov khoom no tsis ruaj khov thiab tuaj yeem hloov mus rau ammonia thiab urea hauv kev daws teeb meem, yog li nws cov tshuaj lom yog tib yam li ntawm urea. Guanidine thiab nws cov derivatives feem ntau muaj tshuaj lom ntau dua li urea.

Lub Hom Phiaj: 1. Nws tuaj yeem siv ua tshuaj nruab nrab, tshuaj tua kab, zas thiab lwm yam organic synthesis. Nws tuaj yeem siv los coj los ua ke 2-Aminopyrimidine, 2-amino-6-methylpyrimidine thiab 2-amino-4,6-dimethylpyrimidine. Nws yog cov khoom nruab nrab rau kev tsim cov sulfadiazine, sulfamethylpyrimidine thiab sulfadimidine.

2. Guanidine hydrochloride (lossis guanidine nitrate) reacts nrog ethyl cyanoacetate los ua 2,4-diamino-6-hydroxypyrimidine, uas yog siv los coj los tiv thaiv cov tshuaj tiv thaiv ntshav qab zib folic acid. Nws kuj tseem siv tau ua antistatic tus neeg sawv cev rau hluavtaws fibers.

3. Nws kuj tseem siv tau ua cov protein ua denaturant.

1. Raws li muaj zog denaturant hauv kev sim ntawm rho tawm tag nrho RNA. Guanidine hydrochloride tov tuaj yeem yaj protein, ua rau lub cell teeb meem puas tsuaj, nuclear protein theem nrab cov qauv kev puas tsuaj, cais tawm ntawm nucleic acid, ntxiv rau, RNase tuaj yeem ua rau tsis muaj zog los ntawm kev txo tus neeg sawv cev xws li guanidine hydrochloride.

hluavtaws qauv

Siv dicyandiamide thiab ammonium ntsev (ammonium chloride) ua cov ntaub ntawv raw, cov roj av guanidine hydrochloride tau txais los ntawm melting cov tshuaj tiv thaiv ntawm 170-230 ℃, thiab cov khoom tiav tiav tau los ntawm kev ua kom zoo.

Sib cuag tswj

1. Tsis txhob nqus cov hmoov av

2. Kev phom sij yog tias nqos

3. Qhov muag tsis pom kev

4. Kev ua haujlwm ntawm daim tawv nqaij

Kev tiv thaiv tus kheej

1. Hnav cov khaub ncaws tiv thaiv kom tsis txhob kov lossis nqus tau; 2. Tsis txhob haus dej, noj lossis haus luam yeeb ntawm chaw ua haujlwm; 3. Siv tsom iav qhov tsom iav
