Maltose is the two-unit member of the amylose homologous series, the key structural motif of starch. Maltose ( or ), also known as maltobiose or malt sugar, is a disaccharide formed from two units of glucose joined with an α(1→4) bond. [citation needed], Like glucose, maltose is a reducing sugar, because the ring of one of the two glucose units can open to present a free aldehyde group; the other one cannot because of the nature of the glycosidic bond.

As water ionizes into H+ and OH-, it will break apart a molecule such as maltose into two glucose molecules. [5], Maltose was 'discovered' by Augustin-Pierre Dubrunfaut, although this discovery was not widely accepted until it was confirmed in 1872 by Irish chemist and brewer Cornelius O'Sullivan. It’s created in seeds and other parts of plants as they break down their stored energy in order to sprout.

It is also present in highly variable quantities in partially hydrolysed starch products like maltodextrin, corn syrup and acid-thinned starch. 2. Xingchu Gong, Huali Chen, Jianyang Pan, Haibin Qu. Maltose (malt sugar) is a disaccharide consisting of two molecules of glucose interconnected.Maltose soluble in water, insoluble in alcohol and ether.In animals maltose is formed by the enzymatic breakdown of starch and other polysaccharides (for example, in the process of digestion or under the influence of malt). Dissolved in water, ethanol-soluble and insoluble in ether. It is obvious to one who does a great deal of cooking that a sugar that requires 6 pounds of water to dissolve 1 pound of sugar, could not be used for concentrated sugar products like jellies, jams, frostings, or even cakes..

Its solubility in ethanol is 0.0111g at 40°C and 0.0270g at 60°C per 100g solution. [citation needed], Maltose in aqueous solution exhibits mutarotation, because the α and β isomers that are formed by the different conformations of the anomeric carbon have different specific rotations, and in aqueous solutions, these two forms are in equilibrium. Paul Brack, S.E. When alpha-amylase breaks down starch, it removes two glucose units at a time, producing maltose. C 12 H 22 O 11 + 24H 2 SO 4 → 12CO 2 + 35H 2 O + 24SO 2. An example of this reaction is found in germinating seeds, which is why it was named after malt. Maltodextrin is a polysaccharide that is used as a food additive.
