D-Galactose e masani ona faʻaaogaina i falemaʻi, meaʻai ma mea teuteu.I totonu o fale talavai, e masani ona faʻaaogaina e avea o se mea e faʻaogaina i vailaʻau eseese ma o se mea e faʻaogaina i luga o faʻasalalauga faʻasalalauga.Ua lauiloa ona o lona gafatia e faʻaleleia le mautu ma faʻaleleia le solubility o vailaʻau faʻamalosi.E le gata i lea, o le D-galactose e faʻaaogaina i fale suʻesuʻe suʻesuʻe e suʻesuʻe ai le tuputupu aʻe o sela, metabolism, ma le glycosylation.
I totonu o pisinisi taumafa, D-galactose e mafai ona faʻaaogaina e avea o se suamalie masani ma le faʻaleleia o meaʻai.E faʻaaogaina i le gaosiga o meaʻai, meainu ma meaʻai susu.O lona suamalie uiga ese, tu'ufa'atasia ma le maualalo o le kalori, ua avea ai ma sui lelei mo i latou e mana'omia se isi suka.E le gata i lea, ua maua le D-galactose o loʻo iai ni mea faʻamaʻi e faʻaleleia ai le tuputupu aʻe o siama aoga o le manava ma lagolagoina le soifua maloloina o meaʻai.
