O le L-Valine o se mea'ai taua tele mo puaa ma moa e pei o le lysine, theonine, methionine ma le tryptophan.I fua fa'atatau a Europa, L-Valine e masani ona manatu o le amino acid fa'atapula'a lona lima.Talu ai e le mafai ona faʻapipiʻiina i le tino, e manaʻomia le faʻaopoopoga mai meaʻai.Valine o se amino acid filifili lala faatasi ma leucine ma isoleucine, e aofia ai i le tele o galuega taua.E mafai ona fesoasoani i le faʻaleleia atili o le susu mo le fafagaina o le lulu ma faʻaleleia le puipuiga o manu.
2. Mo Mea'ai Vasega Valine:
O le L-Valine o se amino acid filifili lala, faatasi ai ma le leucine ma le isoleucine, e taua tele e toe faaleleia ai aano, kulukose masani o le toto ma maua ai le malosi mo le tino o le tagata, aemaise lava mo faamalositino malosi.O le mea lea, e mafai ona faʻaaogaina mo mea inu taʻaloga.E le gata i lea, e mafai foi ona faʻaaogaina Valine e fai ma meaʻai faʻaopoopo i fale falaoa e faʻaleleia ai le tofo o meaʻai.Sa fa'aaogaina fo'i e fai ma mea'ai fa'aopoopo i fale gaosi mea'ai ma meainu.E le gata i lea, e iai sona sao taua i le faatumauina o le malosi o le mafaufau, faʻamaopoopo maso ma le toʻa o lagona.L-Valine o se amino acid taua e maua i polotini;taua mo le tuputupu ae lelei o pepe ma mo le tuputupu ae o tamaiti ma le paleni nitrogen i tagata matutua.
3. Mo Vailaau Vasega Valine:
I le avea ai ma se tasi o vaiinu amino acid, L-Valine e mafai ona faʻaaogaina e togafitia ai nisi faʻamaʻi ate.E le gata i lea, o le valine o se tasi o mea muamua mo le tuufaatasia o fualaau fou.
L-Valine e mafai ona faʻaaogaina mo suʻesuʻega faʻaola kemikolo, le saunia o ala o aganuʻu aganuʻu.L-Valine na faʻaaogaina foi e avea ma amino acids faʻamaʻi taumafa i vailaʻau.
E lelei foi le L-Valine mo le faasa'oina o le ituaiga o faaletonu o le amino acid e mafai ona mafua ona o vaisu.
