Detailed explanation-1: -These molecules are also known as lipogylcans due to the presence of lipid and sugar molecules. The lipopolysaccharides are composed of: Lipid A: the hydrophobic domain, which is an endotoxin and the main virulence factor. O-antigen, the repeating hydrophilic distal oligosaccharide.

Detailed explanation-2: -LPS is a large glycolipid composed of three structural domains: lipid A, the core oligosaccharide, and the O antigen (Fig. 1B) (9).

Detailed explanation-3: -Source and Exposure Endotoxin is found in Gram-negative bacteria and bacterial products or debris. Thus, endotoxin is widely present in the environment, including dust, animal waste, foods, and other materials generated from, or exposed to, Gram-negative bacterial products.
