Final answer:

Lipopolysaccharide (LPS) in Gram-negative bacteria plays crucial roles in protection, stability, and immune response triggering.


Explanation:

Lipopolysaccharide (LPS) is a toxin found in the outer membrane of Gram-negative bacteria, which consists of Lipid A, a core polysaccharide, and an O side chain. LPS plays roles in providing protection, stabilizing the outer membrane, and triggering immune responses in hosts.

The O-antigen or O-polysaccharide represents the outermost part of the LPS structure, while lipid A acts as an endotoxin that can cause symptoms of illness and even endotoxic shock if released in large amounts into the bloodstream.
