Nws yog tshuaj chiral nrog ib lub chaw chiralthiab tshwm sim ua khub ntawm enantiomers. (S)-penicillamine yog eutomer nrog rau qhov xav tau kev tiv thaiv kab mob thaum lub (S)-penicillamine yog tshuaj lom heev.
Penicillamine muaj pes tsawg lub chaw chiral?
Zoo li feem ntau cov amino acids, nws yog cov khoom tsis muaj xim uas muaj nyob rau hauv daim ntawv zwitterionic ntawm physiological pH. Penicillamine yog cov tshuaj chiral nrog ib lub chaw stereogenicthiab muaj nyob ua ib khub ntawm enantiomers.
Muaj pes tsawg lub chaw chirality tam sim no?
Muaj rau lub chaw chiral uas tau sib koom ua plaub pawg sib txawv. Nco tseg: Chiral chaw tseem hu ua stereogenic chaw. Thaum daim iav duab ntawm achiral carbon yog tig, thiab cov qauv tuaj yeem ua raws li ib leeg, lawv cov duab iav tau hais tias yog achiral.
Muaj pes tsawg lub chaw chirality nyob hauv benazepril?
Benazepril hydrochloride muaj ob lub chaw stereogenic, tab sis tam sim no muaj nyob rau hauv ib qho enantiomer (S, S configuration) rau kev kho mob ntshav siab.
Puas muaj chirality centers muaj pes tsawg tus stereoisomers muaj?
Kev piav qhia: Qhov siab tshaj plaws ntawm cov stereoisomers uas ib lub molecule tuaj yeem muaj yog 2n, qhov twg n yog tus naj npawb ntawm chiral centres. Ib lub molecule nrog peb lub chaw chiral yuav muaj 23=8 stereoisomers. Piv txwv li, cov aldopentoses tag nrho muaj peb chiral carbons, thiab muaj yim stereoisomers.
