Lipopolysaccharide Core Antigen (LPS Core Antigen)

Target
LPS Core Antigen
Molecular classification
Glycolipid, Oligosaccharide
01

Overview

The lipopolysaccharide core antigen is a central component of the LPS molecule, a major constituent of the outer membrane of Gram-negative bacteria. It is a nonrepeating oligosaccharide chain that links lipid A to the O-antigen. The core oligosaccharide is crucial for bacterial structural integrity, acts as a permeability barrier, and can be recognized by specific antibodies. While not a direct therapeutic target, its structure and interactions with the host immune system are relevant to bacterial pathogenesis and potential therapeutic interventions.
