Kojitriose α-anomer is a trisaccharide, which means it is a carbohydrate composed of three monosaccharide units. Specifically, it is a type of kojitriose, a sugar that is formed during the fermentation process by the action of enzymes from Aspergillus oryzae, commonly known as koji. The α-anomer refers to the specific configuration of the glycosidic bond between the monosaccharide units, where the hydroxyl group (-OH) is on the opposite side of the carbon chain compared to the anomeric carbon. This particular arrangement influences the molecule's chemical properties and reactivity. Kojitriose α-anomer is significant in the field of biochemistry and food science, particularly in the context of fermentation processes used in the production of various foods and beverages, such as sake, miso, and soy sauce.

Check Digit Verification of cas no

The CAS Registry Mumber 6917-17-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,1 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6917-17:
(6*6)+(5*9)+(4*1)+(3*7)+(2*1)+(1*7)=115
115 % 10 = 5
So 6917-17-5 is a valid CAS Registry Number.

Enzymatic synthesis of mannobioses and mannotrioses by reverse hydrolysis using α-mannosidase from Aspergillus niger

Ajisaka, Katsumi,Matsuo, Ichiro,Isomura, Megumi,Fujimoto, Hiroshi,Shirakabe, Mayumi,Okawa, Mitsuyo

, p. 123 - 130 (2007/10/02)

Various manno-oligosaccharides including α-D-man-(12)-D-man and α-D-man-(12)-α-D-man-(12)-D-man were formed when a highly concentrated mannose solution was incubated in the presence of α-mannosidase from Aspergillus niger. α-D-Man-(12)-D-man and α-D-man-(12)-α-D-man-(12)-D-man were isolated by activated carbon chromatography followed by high performance liquid chromatography using an amino-silica column.In addition to the above oligosaccharides, α-D-man-(13)-D-man, α-D-man-(16)-D-man, and α-D-man-(12)-α-D-man-(16)-D-man were also isolated.

ACETOLYSIS OF Leukonostoc mesenteroides NRRL B-1299 DEXTRAN. ISOLATION AND CHARACTERIZATION OF OLIGOSACCHARIDES CONTAINING SECONDARY LINKAGES FROM THE BORATE-SOLUBLE FRACTION

Watanabe, Toshiyuki,Chiba, Michiko,Matsuda, Yutaka,Sakurai, Fukuko,Kobayashi, Mikihiko,Matsuda, Kazuo

, p. 119 - 128 (2007/10/02)

Fractionation of the deacetylated acetolyzate of the borate-soluble fraction of the dextran elaborated by Leuconostoc mesenteroides MRRL B-1299 gave, after chromatography on charcoal-Celite, preparative paper-chromatography, and paper electrophoresis, four trisaccharide fractions and four tetrasaccharide fractions.The isolated oligosaccharides were characterized by their paper-chromatographic mobility, examination of partial acid-hydrolyzates of the oligosaccharides and their corresponding alditols, and methylation analysis.These oligosaccharides were shown to be (a) kojitriose (1), (b) isomaltotriose (2), (c) a mixture of 2-O-α-isomaltosyl-D-glucose (3), 21-O-α-D-glucosylisomaltose (4), and 2-O-α-nigerosyl-D-glucose (5), (d) 6-O-α-kojibiosyl-D-glucose (6), (e) isomaltotetraose (7), (f) a mixture of 2-O-α-isomaltotriosyl-D-glucose (8) and 21-O-α-D-glycosylisomaltotriose (9), (g) 6-O-α-kojitriosyl-D-glucose (10), and (h) 63-O-α-D-glucosylkojitriose (11), respectively.Some of these oligosaccharides are newly isolated and characterized.
