L-cystine HCL ine kugadzikana kwakanaka
Nhanganyaya
L-cystine hydrochloride inowanzo chena crystalline poda, inonyungudika mumvura uye doro zvinonyungudutsa. Kunyungudika kwayo kunenge 213-216 degrees Celsius. L-cystine hydrochloride ine kugadzikana kwakanaka uye haisi nyore kuora. Iyo yakanyanya kugadzikana pasi pekusarerekera kana zvishoma acidic mamiriro, uye inoora pasi pemamiriro e alkaline. Pamusoro pazvo, komboni yacho inonzwa kuchiedza nekupisa uye inoda kuchengetwa munzvimbo inotonhorera, yakaoma.
