Maltose (/ ˈ m ɔː l t oʊ s / [2] or / ˈ m ɔː l t oʊ z / [3]), also known as maltobiose or malt sugar, is a disaccharide formed from two units of glucose joined with an α(1→4) bond. In the isomer isomaltose , the two glucose molecules are joined with an α(1→6) bond.

Chemical formula. C 12 H 24 O 11: Molar mass: 344.313 g·mol −1 Melting point: ... Maltitol is a disaccharide produced by hydrogenation of maltose obtained from starch.
Amylose A is a parallel double-helix of linear chains of glucose. Amylose is made up of α(1→4) bound glucose molecules. The carbon atoms on glucose are numbered, starting at the aldehyde (C=O) carbon, so, in amylose, the 1-carbon on one glucose molecule is linked to the 4-carbon on the next glucose molecule (α(1→4) bonds).

Hydrolysis of (1→4)-α-D-glucosidic linkages in polysaccharides so as to remove successive maltose units from the non-reducing ends of the chains This enzyme acts on starch , glycogen and related polysaccharides and oligosaccharides producing beta- maltose by an inversion.

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]
The chemical family has had a history of changes in classification. As of 2023, a digestion-resistant maltodextrin is considered a resistant dextrin [ 7 ] and a resistant starch of type 5. [ 9 ] [ 10 ] [ a ] Another study contrasted resistant dextrins and resistant maltodextrins, finding them to differ chemically and functionally. [ 11 ]
