So if we, for example, zoom in on this region, we get the following diagram, as shown. So, the Peptidoglycan consists of two types of amino sugars or sugars, connected by beta one four glycocytic linkages, creating a polysaccharide chain. So these are the polysaccharide chains, and these individual sugars are connected by beta one four glycosytic linkages. Now, two or more polysaccharide chains. So one and two. So let's say these two polysaccharide chains are connected by cross links between these amino acids, shown in purple.
