They can sometimes be the toxic metabolic wastes of the organisms. Endotoxins are part of the Gram (-) bacterial cell wall and are Lipids + Sugars while Exotoxins typically come from Gram (+) bacteria and are PROTEINS that are excreted. Exotoxins are usually heat labile proteins secreted by certain species of bacteria which diffuse into the surrounding medium. Endotoxins are heat stable lipopolysaccharide-protein complexes which form structural components of cell wall of Gram Negative Bacteria and liberated only on cell lysis or death of bacteria. That's why they are called endotoxin. Endotoxins are lipopolysaccharide, which is an integral part of the cell wall of Gram-negative bacteria. Kestabilan haba endotoxin dan eksotoksin. Although some gram-negative pathogens produce exotoxins, the majority are produced by gram-positive pathogens.

Endotoxins are bonded within the bacterial cell wall and released upon the death of the bacterium. Endotoxin is mainly composed of lipopolysaccharide complexes. Endotoxins are relatively stable and can withstand several hours above 60-degree centigrade. Exotoxins can travel from a source of infection to a distant part of the body and cause damage. Toxins and enzymes play important role in pathogenecity. Endotoxins are the lipopolysaccharide-protein complexes, produced at the time of cell death. Toxins are micro molecules but can also be peptides or proteins produced by cells and they have the ability to cause diseases and/or structural damage once they are in contact with the tissues.
