Sign in to saveAlso known as Sakebiose, 3-O-alpha-D-glucopyranosyl-D-glucopyranose, alpha-D-Glup-(1->3)-D-Glu, alpha-D-Glup-(1->3)-D-Glup
Nigerose, also known as sakebiose, is an unfermentable sugar obtained by partial hydrolysis of nigeran, a polysaccharide found in black mold, but is also readily extracted from the dextrans found in rice molds and many other fermenting microorganisms, such as L. mesenteroides. It is a disaccharide made of two glucose residues, connected with a 1->3 link. It is a product of the caramelization of glucose.
