L-Phenylalanine CAS 63-91-2 mo le Vasega a le Foma (USP)
Faʻaogaina:
L-Phenylalanine (Faapuupuuina Phe) o se taua amino acid ma na o le pau lea o le ituaiga o phenylalanine maua i polotini. O se tasi o le 18 masani amino acids, ma o se tasi o le valu taua amino acids i le tino o le tagata.
I le avea ai ma mea e faʻaopoopo ai meaʻai, o le L-phenylalanine e mafai ona vaʻaia o se vaega o le benzyl ua suia mo le vaega o le methyl o le alanine, poʻo se vaega o le phenyl e sui ai le hydrogen terminal of alanine. Tele i le tino e ala i le phenylalanine hydroxylase faʻamamaina oxidation i tyrosine, ma gaosia ma tyrosine taua neurotransmitters ma homone, e auai i le tino metabolism o suka ma gaʻo gaʻo.
L-phenylalanine o se bioactive aromatic amino acid. O se tatau amino acid e le mafai ona lava-gaosia e tagata ma manu. E manaʻomia e se tagata le inuina o le 2.2g L-phenylalanine i aso uma. I le avea ai ma se tasi o le valu manaʻomia amino acid mo tagata tino, ua lautele faʻaaogaina i vailaʻau ma meaʻai faʻaopopo pisinisi. O se vaega taua o tuiina amino acid. I pisinisi gaosi meaʻai, L-phenylalanine mafai ona faʻaopopoina i fale fai meaʻai. Ma o meaʻai a le phenylalanine e mafai ona faʻalauteleina ma e le amido-carboxylation ma le glucide.
L-phenylalanine mafai faʻalauteleina meaai manogi ma tausia le paleni o tatau amino acid. I falemaʻi falemaʻi, L-phenylalanine o loʻo faʻaaogaina ose totonugalemu o nisi amino anticancer vailaʻau pei o formylmerphalanum ma isi O loʻo faʻaaogaina foi e gaosia adrenalin, thyroxin ma melanin. O le isi mea taua talosaga o le tuʻufaʻatasia o le aspartame ma le L-aspartic acid.
L - phenylalanine o le autu mata mea o le taua meaʻai faʻaopopo - suamalie Aspartame (Aspartame). I le avea ai o se tasi o amino acid taua i le tino, e masani ona faʻaaogaina le L-phenylalanine mo le amino acid transfusion ma le amino acid vailaʻau i totonu o le kamupani vailaʻau.
