3-Deoxy-D-manno-2-octulosonic acid (Cat No.:R000076) is a sugar acid commonly found in the lipopolysaccharide (LPS) of Gram-negative bacteria. It plays a crucial role in the structural integrity of the bacterial outer membrane and is a key component of the lipid A region of LPS, which is responsible for the endotoxic activity of these bacteria. The ammonium salt form of Kdo is often used in biochemical and microbiological research as a substrate or standard in assays and experiments aimed at studying the biosynthesis and function of bacterial LPS.
