Common NameLactitol
DescriptionLactitol, also known as importal or oponaf, belongs to the class of organic compounds known as fatty acyl glycosides of mono- and disaccharides. Fatty acyl glycosides of mono- and disaccharides are compounds composed of a mono- or disaccharide moiety linked to one hydroxyl group of a fatty alcohol or of a phosphorylated alcohol (phosphoprenols), a hydroxy fatty acid or to one carboxyl group of a fatty acid (ester linkage) or to an amino alcohol. Lactitol is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, Lactitol is found, on average, in the highest concentration within milk (cow). Lactitol has also been detected, but not quantified in, herbs and spices. Lactitol was first documented in 1987 (PMID: 2885579). This could make lactitol a potential biomarker for the consumption of these foods (PMID: 10654158) (PMID: 1596932) (PMID: 21853265) (PMID: 23165913).
