QUICK LINKS

Kojibiose falls under the category of organic compounds known as fatty acyl glycosides of mono- and disaccharides. These compounds consist of a mono- or disaccharide unit linked to one hydroxyl group of a fatty alcohol or phosphorylated alcohol (phosphoprenols), a hydroxy fatty acid, or one carboxyl group of a fatty acid (ester linkage), or to an amino alcohol. Being soluble in water, kojibiose exhibits very weak acidity (based on its pKa). Inside the cell, kojibiose is predominantly found in the cytoplasm.
