DL-Cysteine (H-DL-Cys-OH) (CAS: 3374-22-9), sulfure munali amino asidi kuti propanoic asidi ndi amino gulu pa udindo 2 ndi gulu sulfanyl pa udindo 3. DL-Cysteine ndi covalently kugwirizana dimeric nonessential amino asidi wopangidwa ndi makutidwe ndi okosijeni wa CYSTEINE.Mamolekyu awiri a cysteine amalumikizidwa pamodzi ndi mlatho wa disulfide kupanga cystine.Cystine ndi amino acid osafunikira omwe amagwira ntchito ngati chopatsa thanzi komanso chopatsa thanzi.Amasungunuka pang'ono m'madzi ndi mowa.imapangitsa kuti puloteni yonse ikhale yabwino m'zakudya zomwe zimakhala ndi mapuloteni osasinthika.
DL-Cysteine ndi amino acid osafunikira omwe amatha kupangidwa ndi thupi la munthu pansi pamikhalidwe yabwinobwino ngati pali methionine yokwanira.Cysteine nthawi zambiri amagwiritsidwa ntchito ngati kalambulabwalo m'mafakitale azakudya ndi zamankhwala.Cysteine amagwiritsidwa ntchito ngati chothandizira pophika, monga chowonjezera mu ndudu, komanso pokonza zokometsera za nyama.
