O se vailaʻau taua ma vailaʻau faʻapisinisi, e masani ona faʻaaogaina i le gaosiga o le cellulose acetate mo ata pue ata, polyvinyl acetate mo le faʻapipiʻi o laupapa, ma le gaosia o alava ma ie. I totonu o fale, o le faʻamaʻaina o le acetic acid e masani ona faʻaaogaina i mea e faʻaaogaina ai meaʻai. I totonu o meaʻai, o le acetic acid o loʻo faʻatonutonuina e le food additive code E260 o se acidity regulator ma o se meaʻai. I le biochemistry, o le acetyl group, na maua mai i le acetic acid, e taua i mea ola uma. Pe a faʻapipiʻi i le coenzyme A, e taua tele i le metabolism o carbohydrates ma gaʻo. Fesili: O le a le ituaiga o le acid E260?
