    Fa'aoga

    Pa'epa'e tioata pa'epa'e
    Pa'epa'e, tioata tioata po'o le pau'u e iai sona manogi fa'apitoa.E tasi le g e liusua ile 30 mL ole vai.E mafai ona solu i totonu o vai vai vai ma vaifofo o alkali hydroxides.E matua solu i le ava malosi, ma e toetoe lava a le mafai ona solu i le eter.E le mafai ona gaoioi.Ole pH ole 1 ile 100 fofo ole va ole 5.6 ma le 6.1.E mafai ona saunia lenei mea e ala i le fa'aopoopoina o le methanethiol i le acrolein;e ala i le faaliliuina o vailaau o le methylthiopropionic aldehyde.

    d,l-Methionine e iai sona manogi uiga.O se amino acid taua ma e faʻaaogaina foi e fai ma meaʻai ma meaʻai faaopoopo.

    Gaosiga o mea fa'afefiloi e feso'ota'i ma le tofo o mea'ai mai le fa'aleagaina e Strecker o le DL-methionine.O le fa'aopoopoina o le methionine i le aofa'i talafeagai i nei mea'ai e ono fa'amoemoe e fa'aleleia ai le tau o porotini.I le tamaoaiga, DL-methionine e sili ona lelei.O se amino acid nonpolar taua ma oxidative stress puipuiga properties.DL-Methionine o nisi taimi e tuuina atu o se faaopoopoga i taifau;e fesoasoani e taofia maile mai le faaleagaina o le mutia e ala i le faaitiitia o le pH o le urine.Methionine e faatagaina e fai ma faʻaopoopoga i fafaga moa faʻaola i lalo ole polokalame faʻaletino faʻamaonia a Amerika.
