Maltotetraose is a tetrasaccharide that is composed of glucose molecules linked by alpha-1,4 glycosidic bonds and has been found in B. stearothermophilus.1,2,3,4 It increases the alpha-amylase synthesis rate in B. stearothermophilus 3-fold greater than sucrose or glucose when used at a concentration of 0.1mM.2 Maltotetraose (750ug/ml) inhibits the growth of E. carotovora in a cylinder-agar plate assay but does not affect the growth of several other microorganisms.4 It also inhibits TNF-alpha-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 20uM.5 Synonyms: O-alpha-D-glucopyranosyl-(14)-O-alpha-D-glucopyranosyl-(14)-O-alpha-D-glucopyranosyl-(14)-D-Glucose, Amylotetraose, alpha-1,4-Tetraglucose CAS No: 34612-38-9 Molecular Formula: C24H42O21 Molecular Weight: 666.58 Appearance: White to off-white powder Purity: 95% Melting Point: 209-211C (dec.)
