Diagram showing orientation and location of different alpha-glucan linkages. α-Glucans ( alpha- glucans) are polysaccharides of D-glucose monomers linked with glycosidic bonds of the alpha form. α-Glucans use cofactors in a cofactor site in order to activate a glucan phosphorylase enzyme. This enzyme causes a reaction that transfers a ...
It is defined as "catalysis of the hydrolysis of terminal, non-reducing alpha-linked alpha-D-glucose residue with release of alpha-D-glucose." In this sense, "alpha-glucosidase" can encompass a wide range of enzyme activitiess, differing by the linkage of their terminal (1→3, 1→4, or 1→6), the specific identity of their substrate (sucrose ...
A glycosidic bond or glycosidic linkage is a type of ether bond that joins a carbohydrate (sugar) molecule to another group, which may or may not be another carbohydrate. Formation of ethyl glucoside: Glucose and ethanol combine to form ethyl glucoside and water. The reaction often favors formation of the α-glycosidic bond as shown due to the ...
α(1→4)-glycosidic linkages in the glycogen oligomer α(1→4)-glycosidic and α(1→6)-glycosidic linkages in the glycogen oligomer. Glycogen is a branched biopolymer consisting of linear chains of glucose residues with an average chain length of approximately 8–12 glucose units and 2,000-60,000 residues per one molecule of glycogen.

The polymer main chain consists of α-1,6 glycosidic linkages between glucose monomers, with branches from α-1,3 linkages. This characteristic branching distinguishes a dextran from a dextrin, which is a straight chain glucose polymer tethered by α-1,4 or α-1,6 linkages. [2]
[6] [7] In general, β-1,3 linkages are created by 1,3-Beta-glucan synthase, and β-1,4 linkages are created by cellulose synthase. The process leading to β-1,6 linkages is poorly understood: although genes important in the process have been identified, not much is known about what each of them do. [8]
1,4-a-glucan 6-a-glucosyltransferase. In enzymology, a 1,4-alpha-glucan 6-alpha-glucosyltransferase ( EC 2.4.1.24) is an enzyme that catalyzes the chemical reaction that transfers an alpha-D-glucosyl residue in a 1,4-alpha-D- glucan to the primary hydroxyl group of glucose or 1,4-alpha-D-glucan. This enzyme belongs to the family of ...
