L-cysteine Base | 52-90-4
Bayanin samfur:
Cysteine fari crystal ne ko crystalline foda, mai narkewa a cikin ruwa, dan kadan wari, insoluble a cikin ethanol, insoluble a Organic kaushi kamar ether. Matsayin narkewa 240 ℃, tsarin monoclinic. Cysteine daya ne daga cikin amino acid mai sulfur, wanda ba shi da mahimmanci amino acid.
A cikin kwayoyin halitta, ana maye gurbin zarra na sulfur na methionine tare da zarra na oxygen na hydroxyl na serine, kuma an haɗa shi ta hanyar cystathionine.
Daga cysteine, ana iya samar da glutathione. glycerol. Cysteine tsayayyen acid ne, amma yana da sauƙin oxidized zuwa cystine a cikin tsaka tsaki da mafita na alkaline.
Ingancin L-cysteine Base:
Yana da haɗin kai a cikin jiki, da dai sauransu.
Yadda ya kamata hanawa da magance raunin radiation.
Yana kula da aikin sulfhydrylase mai mahimmanci a cikin samar da keratin na sunadaran fata, kuma yana haɓaka ƙungiyoyin sulfur don kula da yanayin fata na yau da kullun da daidaita ma'aunin melanin da ke haifar da sel pigment a cikin mafi ƙasƙanci Layer na epidermis. Yana da matukar manufa na halitta whitening kwaskwarima.
Duk lokacin da kumburi ko rashin lafiyan ya faru, sulfydrylase irin su cholphosphatase yana raguwa, kuma ƙarin L-cysteine na iya kula da aikin sulfydrylase kuma inganta alamun fata na kumburi da rashin lafiyan.
Yana da tasirin narkar da keratin, don haka yana da tasiri ga cututtukan fata tare da keratin hypertrophy.
Yana da aikin hana tsufa na halitta.
