  <description>Alpha-Maltotriose is a chemical compound with the formula C18H32O16. Alpha-Maltotriose belongs to the carbohydrates and carbohydrate conjugates, a subclass of organooxygen compounds within the organic compounds. With an average molecular weight of 504.44 g/mol, Alpha-Maltotriose is a heavy molecule.

This compound is found in or released from 14 recorded sources across several categories. Within food, food processing, and cookware, it is associated with the preparation of malt, the preparation of vinegar, the preparation of wine or sparkling wine, molasses and the treatment of molasses, and agglomerated sugar products, among three other sources. It is also linked to electrical and electronic equipment, specifically amplifiers, microphones, and television systems. Additionally, Alpha-Maltotriose is found in household cleaning and consumer products, including tobacco product cases and other smoking requisites, as well as in building and construction materials such as ceilings.

In biological systems, Alpha-Maltotriose interacts with two recorded protein targets. These targets include the maltodextrin-binding protein (malE) and Alpha-amylase 2B (AMY2B).</description>
