Question

Quizplus · Accepted Answer

Lipid A is the toxic portion of endotoxins, which are part of the lipopolysaccharide (LPS) in the outer membrane of Gram-negative bacteria. The toxic effects are generally similar regardless of the bacterial source, and lipid A itself is not immunogenic. Endotoxins are not proteins; they are lipopolysaccharides.
