Lipopolysaccharides (LPS), also known as lipoglycans, play an important role in the functioning of bacteria. Its various aspects are discussed in this article. The large molecules formed from polysaccharides and lipids are known as lipopolysaccharides. The O-polysaccharide, lipid A, and core are the components of LPS.They are present in the outer membranes of bacteria and function as endotoxins. Eliciting immune responses in animals is also one of its important functions.ipopolysaccharides (LPS), also known as lipoglycans, play an important role in the functioning of bacteria.
