I-D-Galactose isetshenziswa kabanzi ezimbonini zemithi, zokudla nezimonyo.Embonini yezemithi, ivamise ukusetshenziswa njengesamukeli ekwakhiweni kwemithi ehlukahlukene nanjengesithako kumidiya ye-cell culture.Kwaziwa ngekhono layo lokuthuthukisa ukuzinza nokuthuthukisa ukunyibilika kwezithako ezisebenzayo zemithi.Ukwengeza, i-D-galactose isetshenziswa ezindaweni zokucwaninga ukutadisha ukukhula kwamaseli, i-metabolism, nezinqubo ze-glycosylation.
Embonini yokudla, i-D-galactose ingasetshenziswa njengesiphuzo semvelo nesithuthukisi ukunambitheka.Isetshenziselwa ukukhiqizwa kwe-confectionery, iziphuzo kanye nemikhiqizo yobisi.Ubumnandi bayo obuyingqayizivele, obuhlanganiswe nekhalori ephansi, buyenza ibe indawo ekahle yalabo abadinga omunye ushukela.Ukwengeza, i-D-galactose itholwe inezakhiwo ze-prebiotic ezikhuthaza ukukhula kwamagciwane atholakala emathunjini futhi asekele impilo yokugaya ukudla.
