Hiki ke ho?oka?awale ?ia nā kumu o L-cysteine ??i ?elua mau ?āpana:

?

1, In vivo synthesis

Ho?ololi Methionine: Hiki i ke kino o ke kanaka ke ho?ololi i ka methionine (methionine) i L-cysteine ????ma o nā ala metabolic.

Hiki ke ho?ohuihui autologous: Ma ke ?ano he waikawa amino pono ?ole, hiki ke ho?ohui ?ia ?o L-cysteine ????ma nā li?ili?i i loko o ke kino, akā pono ke komo ?ana o nā mea kōkua e like me ka huaora B6.

2、 Loa?a i waho

Mea?ai maoli:

?O nā mea?ai waiwai i ka methionine, e like me ka i?a, nā hua manu, ka i?a, a me nā mea ?ē a?e, hiki ke ho?oikaika i ka synthesis o L-cysteine ????i ke kino ma o ka lawe ?ana.

?O nā mea?ai i loa?a pololei i ka L-cysteine: ?O kekahi mau ?i?o (e like me ka moa) a me nā huahana waiu he li?ili?i ka L-cysteine.
