Metabolite Identification
Common NameD-Maltose
DescriptionMaltose, also known as alpha-malt sugar or cextromaltose, belongs to the class of organic compounds known as o-glycosyl compounds. These are glycoside in which a sugar group is bonded through one carbon to another group via a O-glycosidic bond. Maltose exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule. Maltose exists in all living species, ranging from bacteria to humans.

Enzymes

General function:
Carbohydrate transport and metabolism
Specific function:
Essential for the degradation of glycogen in lysosomes (PubMed:10723725). Has highest activity on alpha-1,4-linked glycosidic linkages, but can also hydrolyze alpha-1,6-linked glucans.

General function:
Carbohydrate transport and metabolism
Specific function:
Lectin that binds to various sugars: mannose = ManNAc > fucose > GlcNAc > glucose = maltose > galactose > lactose > GalNAc. Could play a role in immune defense.
Gene Name:
CL43
Uniprot ID:
P42916
Molecular weight:
33616.0
General function:
Carbohydrate transport and metabolism
Specific function:
Contributes to the lung's defense against inhaled microorganisms, organic antigens and toxins. Interacts with compounds such as bacterial lipopolysaccharides, oligosaccharides and fatty acids and modulates leukocyte action in immune response. May participate in the extracellular reorganization or turnover of pulmonary surfactant. Binds strongly maltose residues and to a lesser extent other alpha-glucosyl moieties.
