DL-Cysteine (H-DL-Cys-OH) (CAS: 3374-22-9), he waikawa amino whanariki kei roto he waikawa propanoic me te roopu amino kei te tuunga 2 me te roopu sulfanyl i te waahi 3. DL-Cysteine he waikawa amino koretake e honoa ana i roto i te dimeric i hangaia e te oxidation o CYSTEINE.E rua nga ngota ngota o te cysteine ka honoa e te piriti disulfide ki te hanga cystine.Ko te Cystine he waikawa amino koretake e mahi ana hei taapiri matūkai me te kai.He paku noa te wairewa ki te wai me te waipiro.ka whakapai ake i te kounga koiora o te katoa o te pūmua i roto i nga kai kei roto i te pūmua mau tonu.
Ko te DL-Cysteine he waikawa amino kore-tino ka taea te whakahiato e te tinana o te tangata i raro i nga tikanga ahupūngao noa mena kei te waatea te rahinga methionine.Ko te Cysteine te nuinga o te wa e whakamahia ana hei tohu i roto i nga umanga kai me te rongoa.Ka whakamahia te Cysteine hei awhina mo te tunu tunu, hei taapiri i roto i te hikareti, tae atu ki te whakarite i nga kai reka.
