Saldhigga L-cysteine | 52-90-4
Sharaxaada Alaabta:
Cysteine waa kareem cad ama budo crystalline ah, oo ku milma biyaha, wax yar ur leh, aan lagu milmin ethanol, aan milmin karin dareeraha organic sida ether. Meesha dhalaalka 240 ℃, nidaamka monoclinic. Cysteine waa mid ka mid ah amino acids-ka baaruudku ku jiro, taas oo ah amino acid aan muhiim ahayn.
In organismka, atamka baaruudda ee methionine waxaa lagu beddelaa atamka oksijiinta hydroxyl ee serine, waxaana lagu dhex abuuraa cystathionine.
Laga soo bilaabo cysteine, glutathione ayaa laga dhalin karaa. glycerol. Cysteine waa mid xasiloon aashitada, laakiin si fudud ayaa oksaydh loogu sameeyaa cystineka xal dhexdhexaad ah iyo alkaline ah.
Waxtarka saldhigga L-cysteine :
Waxay leedahay isku xirnaanta jirka, iwm.
Si wax ku ool ah uga hortag oo u daweeyo dhaawaca shucaaca.
Waxay ilaalisaa dhaqdhaqaaqa muhiimka ah ee sulfhydrylase ee soosaarka keratin ee borotiinnada maqaarka, waxayna kordhisaa kooxaha sulfur si ay u ilaaliso dheef-shiid kiimikaadka caadiga ah ee maqaarka waxayna nidaamisaa melanin-ka hoose ee ay soo saaraan unugyada midabka ee lakabka ugu hooseeya ee epidermis. Waa qurxinta dabiiciga ah ee caddeynta aad ugu habboon.
Mar kasta oo barar ama xasaasiyadu dhacdo, sulfydrylase sida cholphosphatase waa la dhimaa, iyo kabidda L-cysteine waxay sii wadi kartaa dhaqdhaqaaqa sulfydrylase waxayna hagaajin kartaa calaamadaha maqaarka ee caabuqa iyo xasaasiyadda.
Waxay leedahay saameynta kala dirida keratin, sidaas darteed waxay sidoo kale waxtar u leedahay cudurrada maqaarka ee leh keratin hypertrophy.
Waxay leedahay shaqada ka hortagga gabowga noolaha.
