3-aminopropyl 2-acetamido-2,3-dideoxy-3-{[(3R)-3-hydroxybutanoyl]amino}-beta-D-glucopyranuronosyl-(1->4)-2-acetamido-3-O-acetyl-2,6-dideoxy-alpha-L-galactopyranosyl-(1->3)-2-acetamido-2,6-dideoxy-alpha-D-glucopyranoside
3-aminopropyl 2-acetamido-2,3-dideoxy-3-{[(3r)-3-hydroxybutanoyl]amino}-beta-d-glucopyranuronosyl-(1->4)-2-acetamido-3-o-acetyl-2,6-dideoxy-alpha-l-galactopyranosyl-(1->3)-2-acetamido-2,6-dideoxy-alpha-d-glucopyranoside
An amino trisaccharide that consists of 2-acetamido-2,3-dideoxy-3-{[(3<i>R</i>)-3-hydroxybutanoyl]amino}-β-<small>D</small>-glucopyranuronic acid, 2-acetamido-3-<em>O</em>-acetyl-2,6-dideoxy-α-<small>L</small>-galactopyranose, and 3-aminopropyl 2-acetamido-2,6-dideoxy-α-<small>D</small>-glucopyranoside residues linked sequentially (1→4) and (1→3). It is a derivative of the trisaccharide repeating unit of <em>Pseudomonas aeruginosa</em> serotype O51 O-antigen that contains an amino propyl linker at the reducing end and and an acetamido group instead of the acetimidamido group.
