Ní mór cistín (cistéin) agus meitiainín a ocsaídiú chuig aigéad cistéach agus sulfón meitiainín faoi seach roimh hidrealú.
Cyst(e)ine and methionine must be oxidised to cysteic acid and methionine sulphone respectively prior to hydrolysis.

Déantar meitiainín a chinneadh mar shulfón meitiainín i hidrealasáití de shampla ocsaídithe, ach ríomhtar mar mheitiainín é trí úsáid a bhaint as M meitiaimín: 149,21 g/mol.
Methionine is determined as methionine sulphone in hydrolysates of oxidised sample, but calculated as methionine by using M of methionine: 149,21 g/mol.
Buntuaslagán caighdeánach d’aigéad cistéach agus sulfón meitiainín, c = 1,25 μmol/ml.
Stock standard solution of cysteic acid and methionine sulphone, c = 1,25 μmol/ml.
Tháinig an tÚdarás ar an gconclúid freisin gur foinse éifeachtach meitiainín é L-meitiainín arna tháirgeadh ag Corynebacterium glutamicum KCCM 80245 agus Escherichia coli KCCM 80246 do gach speiceas ainmhíoch agus gur cheart an tsubstaint a chosaint ar dhíghrádú sa chogansach ionas go mbeidh sé chomh héifeachtúil céanna le hathchogantaigh agus atá i speicis neamh-athchogantacha.
The Authority further concluded that L-methionine produced by Corynebacterium glutamicum KCCM 80245 and Escherichia coli KCCM 80246 is an effective source of methionine for all animal species and that in order to be as efficacious in ruminants as in non-ruminant species, the substance should be protected against degradation in the rumen.
Mar thoradh ar an athnuachan ar údarú crágaigh mangainéise d’analóg hiodrocsa meitiainín mar bhreiseán beathaithe, ba cheart Rialachán (AE) Uimh. 350/2010 a aisghairm.
