[Description]

Maltotetraose is a tetrasaccharide that is composed of glucose molecules linked by α-1,4 glycosidic bonds and has been found in B. stearothermophilus. It increases the α-amylase synthesis rate in B. stearothermophilus 3-fold greater than sucrose or glucose (Item No. 23733) when used at a concentration of 0.1 mM. Maltotetraose (750 μg/ml) inhibits the growth of E. carotovora in a cylinder-agar plate assay but does not affect the growth of several other microorganisms. It also inhibits TNF-α-induced expression of intercellular adhesion molecule-1 (ICAM-1) in MOVAS-1 mouse smooth muscle cells (VSMCs) transfected with an ICAM-1 luciferase reporter when used at a concentration of 20 μM.

[Uses]

inhibits AIDS virus infection in vitro and tumor necrosis factor-alpha (TNF), interleukin (IL)-1beta, and causes a marked depression of chemiluminescence activity
[Uses]

Maltotetraose is a maltooligosaccharide that is used for research and diagnostic purposes. They can also be used in nutrients and healthcare.
[Definition]

ChEBI: A maltotetraose tetrasaccharide in which the glucose residue at the reducing end is in the aldehydo open-chain form.
