O le a(S)-3-Hydroxy-gamma-butyrolactoneCAS7331-52-4？

(s) 3-hydroxy - γ - butyrolactone o se vai e le lanu e mafai ona solu i le vai, ava malosi, ma isi solvents organic, ae e le mafai ona faʻafefe i le suauʻu ethers. Ose mea e sili ona taua ole synthesis fa'aleogalemu ma ose punavai sili ona taua (Chiral Pool). E masani ona faʻaaogaina e avea o se mea autu mo le faʻatonutonuina (R) - γ - hydroxy - β - Q hydroxybutyric acid [(R) - GABOB], lea e faʻaaogaina e togafitia ai le hyperlipidemia; (s) Oxiracetam ose fa'atupuina le metabolism o le fai'ai ma lona tu'ufa'atasiga; (s) -3-hydroxytetrahydrofuran e mafai ona maua e ala i le faʻaitiitia, o se mea taua tele o vailaʻau AIDS.
