Talosaga

Fa'aopoopoga mea'ai a le L-Valine. E mafai ona saunia fa'atasi le fa'afefiloi o amino acid ma sauniuniga atoatoa o amino acid ma isi amino acid taua. Fa'aopoopo le valine (1g,/kg) i keke araisa, ma e iai le manogi sesame i le oloa. E mafai fo'i ona fa'aleleia atili ai le tofo o falaoa pe a fa'aaogaina. O le L-Valine o se tasi o amino acid e tolu e fa'alava ma o se amino acid taua e mafai ona togafitia ai le fa'aletonu o le ate ma le fa'aletonu o le tino tutotonu.
