Common NameMaltose
DescriptionD-Maltose, also known as malt sugar, maltobiose or alpha-malt sugar, is a disaccharide consisting of two glucose subunits joined via an alpha-1-4 bond. Carbohydrates are generally divided into different categories based on the number of sugar subunits; monosaccharides (1 sugar subunit), disaccharides (2 sugar subunits), oligosaccharides (3 or more sugar subunits) and polysaccharides (hundreds to thousands of subunits, including starch). Maltose is a common byproduct of starch. When beta-amylase breaks down starch, it removes two glucose units at a time, thereby producing maltose. Maltose can be broken down to glucose by the maltase enzyme, which catalyses the hydrolysis of the glycosidic bond. D-Maltose exists in all living species, ranging from bacteria to humans. 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. Its name comes from malt, combined with the suffix '-ose' which is used in naming all sugars. 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. Maltose, when placed in aqueous solution, exhibits mutarotation. This is because the α and β isomers that are formed by the different conformations of the anomeric carbon have different specific rotations. In aqueous solutions, these two forms are in equilibrium. Maltose has a sweet taste, but is only about 30-60% as sweet as sucrose. Within humans, D-maltose participates in a number of enzymatic reactions. In particular, D-maltose can be converted into Alpha-D-glucose; which is mediated by intestinal maltase-glucoamylase. In addition, D-maltose can be converted into Alpha-D-glucose through its interaction with the enzyme glycogen debranching enzyme. In humans, D-maltose is involved in the metabolic disorder called the sucrase-isomaltase deficiency. Outside of the human body, D-maltose is found in high concentrations a variety of foods such as fruit gums, marshmallows, and oriental wheats. It is found in lower concentrations in bread, bagels, breakfast cereals, crackers, cornmeal, wheat, barley, candies, honey, molasses, beer and wines. Maltose is found mainly in grains and cereals. Wheat, corn, barley and rye all contain varying amounts of maltose. For some foods, cooking can increase the maltose content. For example, raw sweet potatoes don't have any maltose, but cooked sweet potatoes contain maltose at varying amounts depending on the type of sweet potato. Maltose is a component of malt, a substance which is obtained in the process of allowing grain to soften in water and germinate. Maltose is also found in partially hydrolysed starch products like maltodextrin, corn syrup and acid-thinned starch.
