I-DL-Cysteine (H-DL-Cys-OH) (i-CAS: 3374-22-9), i-amino acid enesulfure ene-propanoic acid kunye neqela le-amino kwindawo ye-2 kunye neqela le-sulfanyl kwindawo ye-3. DL-Cysteine yi-covalently dimeric nonessential amino acid eyenziwe yi-oxidation ye-CYSTEINE.Iimolekyuli ezimbini ze-cysteine zidibene kunye nebhulorho ye-disulfide ukwenza i-cystine.I-cystine yi-amino acid engabalulekanga esebenza njengezondlo kunye nezongezo zokutya.Inyibilika kancinane kakhulu emanzini nasetywaleni.iphucula umgangatho webhayoloji weprotheyini iyonke ekutyeni okuqulethe iprotein eyenzeka ngokwemvelo.
I-DL-Cysteine yi-amino acid engabalulekanga enokuthi yenziwe ngumzimba womntu phantsi kweemeko eziqhelekileyo ze-physiological ukuba kukho ubungakanani obaneleyo be-methionine.I-cysteine idla ngokusetyenziswa njenge-precursor kumashishini okutya kunye namayeza.I-Cysteine isetyenziswa njenge-processing aid yokubhaka, njenge-additive kwi-cigarettes, kunye nokulungiswa kwencasa yenyama.
