Meatotino Faaletino ma Vailaau	(s) -3-hydroxy-gamma butyrolactone o se vai lanu, soluble i le vai, ava malosi ma isi solvents organic, insoluble i le suauu ether, ma isi, o se intermediates synthesis organic taua tele, o se punavai taua foi o uiga alofa. E masani ona faʻaaogaina e avea o se vaega autu o le Modulator (R) -gamma-hydroxy-beta-Q hydroxybutyric acid [(R) -GABOB], (R) -GABOB e faʻaaogaina e togafitia ai le hyperlipidemia; (s) -Oxiracetam o se faʻalauiloaina o le faiʻai. metabolism, ae faapea foi lona tuufaatasia; O lona fa'aitiitiga e mafai ona maua (s) -3-hydroxytetrahydrofuran, o se mea taua tele mo togafitiga o vailaʻau AIDS; o le (s)-3-hydroxy-4-bromobutyric acid e fa'apipi'iina mai ai ose mea e mafai ona fa'amautu; Ua liua i le (s) -5-hydroxymethyl-1, 3-oxazolin-2-one avanoa mo le tupulaga aupito lata mai o vailaau antibacterial; E le gata i lea, (s) -n-methyl-3-hydroxypyrrole ma (R) -N-methyl -3-methyl-pyrrole e iai foʻi mea taua faʻaletino, e mafai foi ona maua e ala i le liua faigofie o (s) -3-hydroxy- gamma butyrolactone. Ole tele o oloa fa'anatura e mafai fo'i ona fa'apipi'iina mai (s)-3-hydroxy-γbutyrolactone.

Folasaga

(S) -3-hydroxy-γ-butyrolactone o se faʻalapotopotoga faʻapitoa. O se vai e leai ni lanu ma se tofo suamalie suamalie.

E tele auala mo le saunia o le (S) -3-hydroxy-γ-butyrolactone, lea e masani ona maua e le catalytic hydrogenation. O le auala faʻapitoa o le tali atu lea i se aofaiga talafeagai o le γ-butyrolactone faʻatasi ai ma se faʻamalosi (e pei o le kopa-lead alloy) i se vevela talafeagai ma le mamafa, ma a maeʻa le hydrogenation catalytic, (S) -3-hydroxy-γ-butyrolactone e maua.

Fa'amatalaga Saogalemu: (S)-3-hydroxy-γ-butyrolactone e maualalo le oona i lalo ole fa'aoga lautele ma e le o se vaila'au matautia. E tatau ona faʻaeteete ina ia aloese mai le faʻafesoʻotaʻi ma le paʻu, mata, ma le manava ile taimi ole faʻaoga. Pe a fa'afuase'i ona fa'afeso'ota'i, fa'amama i le vai ma sa'ili fa'afoma'i ile taimi. E tatau ona 'alo'ese mai le fa'amumu ma si'osi'omaga maualuga le vevela, ma 'alofia le fa'afeso'ota'i ma oxidants ma acids. E le gata i lea, e tatau ona faʻaaogaina e tusa ai ma faiga faʻaoga tatau ma faiga saogalemu.
