Glütserooli kasutatakse laialdaselt paljudes tööstus- ja tarbekaupades, nt seebid/pesuained, ravimid, kosmeetikatooted, toiduained, joogid, värvid, vaigud ja paber.
Üldiselt sõltub sigarettides sisalduva glütserooli kogus sigaretimargist. Hollandis moodustab lisatava glütserooli kogus keskmiselt 1% ja maksimaalselt 4,4% kasutatava tubaka kogukaalust. Selline tase on võrreldav ühele sigaretile lisatava glütserooli kogusega ELis tervikuna, kus keskmine kogus on 1,1% ja maksimaalne kogus 4,5% kasutatava tubakakogukaalust. See tähendab, et glütserool on üks enim kasutatavaid tubakalisandeid.
Rasvad on glütserooli (propaan-1,2,3-triooli) ja rasvhapete triestrid. Rasva teket võib ette kujutada kui glütserooli molekuli ja kolme rasvhappe molekuli reaktsiooni, mille käigus moodustub kolm estersidet.
Glycerol is seen in biological systems as an intermediate in carbohydrate and lipid metabolism because surplus carbohydrate can be converted into long chain fatty acids and esterified with the three hydroxyl groups. Glycerol can influence immune reactions in the body through histamines, increased antibody production and by enhancing immune cell activity and is therefore classified as an allergen. In the blood, glycerol can increase blood pressure by preferentially attracting the water from tissues into plasma and lymph. In nephrons, glycerol can increase urine volume by preventing water resorption.
