And these individual polysaccharide chains that themselves consist of disaccharide units, are connected to one another as a result of cross linkages or cross links. So basically, these amino acids connect to one another as a result of a bridge known as the Interbridge. So basically, we have one of the amino acids on this chain, connects to one of the amino acids on this chain, and this is known as an Interbridge. 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.
