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.

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

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

1. Preparation of maltotetrasaccharide by single enzyme method

Maltotetrasaccharide amylase is mainly used to decompose starch to get. Due to the unique molecular structure of the enzyme, the starch needs to be pre-treated, so that its DE va
