O le Bisphenol A (BPA) o se fa'alapotopotoga fa'aola. O le Bisphenol A o se malo e leai se lanu i le samasama e mafai ona solu i solu faʻaola pei ole ketones ma esters.
O se auala masani mo le sauniaina o le bisphenol A e ala i le faʻafefeteina o faʻamaʻi o phenols ma aldehydes, e masani ona faʻaaogaina mea faʻamaʻi. I le faagasologa o sauniuniga, o tulaga tali atu ma le filifiliga o le catalyst e tatau ona pulea ina ia maua ai oloa bisphenol A maualuga-mama.

Fa'amatalaga Saogalemu: O le Bisphenol A ua manatu e o'ona ma e ono afaina ai le si'osi'omaga. O suʻesuʻega ua faʻaalia ai o le BPA e mafai ona i ai se faʻalavelave faʻalavelave i le endocrine system ma e manatu e iai ni aʻafiaga leaga i le fanautama, popole ma le puipuia. E mafai ona i ai se aafiaga le lelei i le atina'eina o pepe ma tamaiti ile taimi umi ole aafia ile BPA.
