生化/生理作用

Lactulose is a synthetic disaccharide derived from galactose and fructose. It is not absorbed in the gut and is frequently used in the treatment of constipation and hepatic encephalopathy. Studies have reported that lactulose administration may cause an increase in fecal nitrogen. It is also known to function as a prebiotic. Lactulose measurements can be used to detect gastrointestinal dysfunctions.

Oligosaccharides derived from lactulose (β-D-Galp-(1 → 4)-D-Fru) are drawing more and more attention nowadays because of their strong resistance to gut digestion, and the interest to discover novel prebiotics. Compared to galactooligosaccharides, currently known structures of lactulose oligosaccharides are very limited. In
