A thiol lossis thiol derivative yog ib qho organosulfur compound ntawm daim ntawv R-SH, qhov twg R sawv cev rau alkyl lossis lwm yam organic hloov. -SH pab pawg ua haujlwm nws tus kheej raug xa mus rau pawg thiol lossis pawg sulfhydryl, lossis pawg sulfanyl.
Pab pawg ntseeg yog dab tsi?
Ib pawg sulfhydryl (tseem hu ua "thiol pawg") muaj cov sulfur atom nrog ob leeg ib leeg, sib koom ua ke rau hydrogenCov pab pawg sulfhydryl muaj nyob hauv peb lub cev thiab feem ntau pom. nyob rau hauv daim ntawv oxidized li disulfide linkages. Cov kev sib txuas ntawm cov disulfide pab txhawb rau tertiary thiab quaternary qauv ntawm cov proteins.
piv txwv ntawm thiol yog dab tsi?
Ib thiol feem ntau muaj qhov kub qis dua li cov hydroxyl compound zoo li cov qauv; Piv txwv li, methanethiol boils ntawm 6 ° C(43 ° F), methanol ntawm 65 ° C (149 ° F). Qhov qis aliphatic thiols muaj txiaj ntsig zoo li ceeb toom cov ntxhiab tsw hauv cov pa roj thiab muaj tshuaj lom me ntsis.
Pab pawg twg ua haujlwm hu ua thiol?
