Metabolite Identification
Common NameMaltohexaose
DescriptionMaltohexaose is a polysaccharide with 6 units of glucose and can be classified as a maltodextrin. Maltodextrin is a polysaccharide that is used as a food additive. It is produced from starch by partial hydrolysis and is usually found as a creamy-white hygroscopic spray-dried powder. Maltodextrin is easily digestible, being absorbed as rapidly as glucose, and might be either moderately sweet or almost flavourless. It is commonly used for the production of natural sodas and candy such as SweeTarts. Maltodextrin consists of D-glucose units connected in chains of variable length. The glucose units are primarily linked with α(1→4) glycosidic bonds. Maltodextrin is typically composed of a mixture of chains that vary from three to nineteen glucose units long. Maltodextrins are classified by DE (dextrose equivalent) and have a DE between 3 to 20. The higher the DE value, the shorter the glucose chains, and the higher the sweetness and solubility. Above DE 20, the European Union's CN code calls it glucose syrup, at DE 10 or lower the customs CN code nomenclature classifies maltodextrins as dextrins (Wikipedia). A 1,4-alpha-D-glucan reacts with H2O to produce maltohexaose. alpha-Amylase is responsible for catalyzing this reaction.
