Folasaga
R-(+) tetrahydrofuranoic acid. O lo'o ta'ua i lalo se fa'amatalaga i nisi o meatotino, fa'aoga, metotia o sauniuniga ma fa'amatalaga saogalemu o le R-(+)tetrahydrofuranoic acid:
Tulaga lelei:
- R-(+)tetrahydrofuranoic acid e leai se lanu e o'o ile lanu samasama ma'alia ma se tofo oona uiga ese.
- E solo i totonu o le vai ma e foliga mai o se vai e feliuliua'i i le vevela o le potu.
- E mafai ona tali atu i isi mea faʻapipiʻi e pei o le esterification, condensation, faʻaititia, ma isi.
Fa'aaogā:
- O le R-(+)tetrahydrofuranoic acid o lo'o fa'aogaina fo'i i le tapenaga o isi mea fa'aola, fa'ata'ita'iga i le tu'ufa'atasiga o palasitika fa'aola e pei ole polylactic acid.
Metotia:
- R-(+)tetrahydrofuranoic acid e mafai ona saunia e auala eseese e pei o le vavaeeseina o mata, faʻaitiitiga vailaʻau, ma metotia enzymatic.
- O le vavae ese o mata o se auala masani e faʻaogaina ai le faʻaogaina e tuʻueseese ai isi isomers o le D-lactate e ala i le filifilia o microorganisms talafeagai poʻo enzymes.
Fa'amatalaga Saogalemu:
- R-(+)tetrahydrofuranoic acid e fai si saogalemu i lalo ole fa'aoga masani.
- Feso'ota'iga umi e ono fa'aita ai le pa'u ma mata, ma e tatau ona fa'aeteete pe a tago.
- Pe a teuina ma faʻapipiʻiina, e tatau ona matua tausisi i faiga faʻaoga saogalemu, ma faʻafesoʻotaʻi ma mea faʻamaʻi malosi ma mea e mu e tatau ona aloese mai ai.
