(Alpha) Limit dextrin is a short chained branched amylopectin remnant, produced by hydrolysis of amylopectin with alpha amylase. Highly branched cyclic dextrin is a dextrin produced from enzymatic breaking of the amylopectin in clusters and using branching enzyme to form large cyclic chains. [9]
Its substrate, alpha-limit dextrin, is a product of amylopectin digestion that retains its 1-6 linkage (its alpha 1-4 linkages having already been broken down by amylase). The product of the enzymatic digestion of alpha-limit dextrin by isomaltase is maltose. Isomaltase helps amylase to digest alpha-limit dextrin to produce maltose.
Limit dextrinase (EC 3.2.1.142, R-enzyme, amylopectin-1,6-glucosidase, dextrin alpha-1,6-glucanohydrolase) is an enzyme with systematic name dextrin 6-alpha-glucanohydrolase. [1] [2] This enzyme catalyses the hydrolysis of (1->6)-alpha-D-glucosidic linkages in alpha- and beta-limits dextrins of amylopectin and glycogen, in amylopectin and pullulan.
Pullulanase (EC 3.2.1.41, limit dextrinase, amylopectin 6-glucanohydrolase, bacterial debranching enzyme, debranching enzyme, α-dextrin endo-1,6-α-glucosidase, R-enzyme, pullulan α-1,6-glucanohydrolase) is a specific kind of glucanase, an amylolytic exoenzyme, that degrades pullulan.
Amylo-α-1,6-glucosidase (EC 3.2.1.33, amylo-1,6-glucosidase, dextrin 6-α-D-glucosidase, amylopectin 1,6-glucosidase, dextrin-1,6-glucosidase, glycogen phosphorylase-limit dextrin α-1,6-glucohydrolase) is an enzyme with systematic name glycogen phosphorylase-limit dextrin 6-α-glucohydrolase.
α-Amylase is an enzyme (EC 3.2.1.1; systematic name 4-α-D-glucan glucanohydrolase) that hydrolyses α bonds of large, α-linked polysaccharides, such as starch and glycogen, yielding shorter chains thereof, dextrins, and maltose, through the following biochemical process: [2]
Wacker Chemie AG uses dedicated enzymes, that can produce alpha-, beta- or gamma-cyclodextrin specifically. This is very valuable especially for the food industry, as only alpha- and gamma-cyclodextrin can be consumed without a daily intake limit. Crystal structure of a rotaxane with an α-cyclodextrin macrocycle. [13]
A definition of a digestion-resistant maltodextrin is: "Resistant maltodextrin/dextrin is a glucose oligosaccharide. Resistant maltodextrin and dextrin products are composed of non-digestible oligosaccharides of glucose molecules that are joined by digestible linkages and non-digestible α-1,2 and α-1,3 linkages."
