Glycine

Glycine(wanda aka rage wa suna Gly), wanda kuma aka sani da acetic acid, amino acid ne wanda ba shi da mahimmanci, tsarin sinadaransa shine C2H5NO2. Glycine amino acid ne na glutathione mai rage yawan antioxidant, wanda galibi ana ƙara shi ta hanyar tushen waje lokacin da jiki ke cikin matsananciyar damuwa, kuma wani lokacin ana kiransa amino acid mai mahimmanci. Glycine yana ɗaya daga cikin amino acid mafi sauƙi.

Kayayyakin sinadarai:

Farin lu'ulu'u mai siffar monoclinic ko hexagonal, ko farin lu'ulu'u mai siffar crystalline. Ba shi da wari, tare da ɗanɗano mai daɗi na musamman. Yana narkewa cikin sauƙi a cikin ruwa, yana narkewa cikin ruwa: 25g/100ml a 25℃; A 50℃, 39.1g/10Chemicalbook0ml; 54.4g/100ml a 75℃; A 100℃, yana da 67.2g/100ml. Ba ya narkewa sosai a cikin ethanol, kusan 0.06g yana narkewa a cikin ethanol mai launin ruwan kasa 100g. Kusan ba ya narkewa a cikin acetone da ether.
