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.
Maltotriose is a trisaccharide (three-part sugar) consisting of three glucose molecules linked with α-1,4 glycosidic bonds. [1]It is most commonly produced by the digestive enzyme alpha-amylase (a common enzyme in human saliva) on amylose in starch.
PubChem can be accessed for free through a web user interface. Millions of compound structures and descriptive datasets can be freely downloaded via FTP. PubChem contains multiple substance descriptions and small molecules with fewer than 100 atoms and 1,000 bonds. More than 80 database vendors contribute to the growing PubChem database. [2]
Hydrolysis reaction of Maltose being broken at the 1-4 alpha-glucosidase linkage. The mechanism of all FamilyGH13 enzymes is to break a α-glucosidase linkage by hydrolyzing it. Maltase focuses on breaking apart maltose, a disaccharide that is a link between 2 units of glucose, at the α-(1->4) bond.

In enzymology, a maltose epimerase (EC 5.1.3.21) is an enzyme that catalyzes the chemical reaction alpha-maltose ⇌ {\displaystyle \rightleftharpoons } beta-maltose Hence, this enzyme has one substrate , alpha-maltose , and one product , beta-maltose .
Prior to the use of computer graphics in representing molecular structure, Robert Corey and Linus Pauling developed a system for representing atoms or groups of atoms from hard wood on a scale of 1 inch = 1 angstrom connected by a clamping device to maintain the molecular configuration. [4]
