: ntawm lossis cuam tshuam rau lub molecule uas tsis yog superimposable ntawm nws daim iav duab.
Lub ntsiab lus ntawm kev hlub yog dab tsi?
Chirality /kaɪˈrælɪtiː/ yog a khoom ntawm asymmetry tseem ceeb hauv ntau ceg ntawm kev tshawb fawbLo lus chirality yog muab los ntawm Greek χειρ (kheir), "tes," ib tug paub chiral khoom. Ib qho khoom lossis lub kaw lus yog chiral yog tias nws txawv ntawm nws daim iav duab; uas yog, nws tsis tuaj yeem superimposed rau nws.
Dab tsi yog qhov txhais zoo tshaj ntawm kev hlub?
/ (kaɪˈrælɪtɪ) / npe. kev teeb tsa lossis txhais tes (sab laug lossis sab xis) ntawm asymmetric, optically active tshuaj compoundtseem hu ua: dissymmetry.
kev hlub yog dab tsi thiab yog vim li cas nws tseem ceeb?
Chirality yog ib lub tswv yim tseem ceeb hauv biology, vim cov hlwb feem ntau yog tsim los ntawm chiral moleculesCov chiral me me xws li amino acids thiab qab zib (daim duab 1, saum) yog lub tsev. blocks ntawm cov molecules loj, xws li cov proteins thiab nucleic acids, uas kuj yog chiral.
txhais li cas los ntawm chirality muab piv txwv?
(i) Chirality yog cov cuab yeej ntawm a molecule kom muaj daim iav tsis-super-imposable. Cov molecules no muaj ib asymmetric carbon atom. Piv txwv li, Butan - 2-ol. (ii) CH3CH(Cl)CH2CH3 yog yooj yim dua hydrolyzed vim yog tsim ntawm ntau ruaj khov theem nrab carbocation.
