Question

Quizplus · Accepted Answer

Endotoxins are part of the outer membrane of the cell wall of Gram-negative bacteria, with Lipid A being the toxic component. They are not proteins but rather complex lipopolysaccharides, and their toxic effects do not significantly vary with the bacterial source. Lipid A is also heat-stable, not heat-sensitive.
