Imithombo ye-L-cysteine ????inokwahlulwa ibe ngamacandelo amabini alandelayo:

?

1, In vivo synthesis

Ukuguqulwa kweMethionine: Umzimba womntu unokuguqula i-methionine (methionine) ibe yi-L-cysteine ????ngeendlela ze-metabolic.

I-autologous synthesis isakhono: Njenge-amino acid engeyomfuneko, i-L-cysteine ????inodityaniswa ngexabiso elincinci emzimbeni, kodwa ifuna ukuthatha inxaxheba kwizinto ezincedisayo ezifana ne-vitamin B6.

2. Ukufunyanwa kwangaphandle

Ukutya kwendalo:

Ukutya okutyebileyo kwi-methionine, njengentlanzi, amaqanda, ukutya kwaselwandle, njl., kunokukhuthaza ukuhlanganiswa kwe-L-cysteine ????kumzimba ngokungena.

Ukutya okuqulethe ngokuthe ngqo i-L-cysteine: Ezinye iinyama (ezifana nenkukhu) kunye neemveliso zobisi ziqulethe ixabiso elincinci le-L-cysteine.
