L-cystine HCL muaj kev ruaj ntseg zoo

L-cystine hydrochloride yog cov organic compound nrog cov tshuaj formula C3H7NO2S·HCl, ntawm cov uas L-cystine yog ib tug natural amino acid uas twb muaj nyob rau hauv lub biological ntiaj teb no ntawm lub ntiaj teb no, nrog rau lom lom thiab antioxidant zog. Daim ntawv hydrochloride txhais tau hais tias cov amino acid nyob rau hauv lub cystine molecule yog ua ke nrog hydrochloric acid los ua ib tug hydrochloride.

    Taw qhia

    L-cystine hydrochloride feem ntau yog dawb crystalline hmoov, soluble nyob rau hauv dej thiab cawv solvents. Nws melting point yog hais txog 213-216 degrees Celsius. L-cystine hydrochloride muaj kev ruaj ntseg zoo thiab tsis yooj yim rau decompose. Nws yog ruaj khov nyob rau hauv nruab nrab los yog me ntsis acidic tej yam kev mob, thiab yuav decompose nyob rau hauv alkaline tej yam kev mob. Tsis tas li ntawd, lub compound yog rhiab heev rau lub teeb thiab cua sov thiab yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav.
