- Which of the following statements about Lipopolysaccharide is FALSE? The lipid A portion is a form of bacterial toxin. The core oligosaccharide contains unusual or unique monosaccharides. The basal ring complexes are composed of the protein flagellin. O The O-linked oligosaccharide is the same "O" antigen used in specific epithets such as "0157:H7". O Lipopolysaccharide is often referred to as bacterial endotoxin.It has long been recognized that breast milk protects infantsfrom infectious diseases, especially those that affect the digestive tract. The main reason for this protection appears tobe a large group of oligosaccharides that are components ofhuman milk.
