So peptide means we have some type of peptide bond, and Glycoin means we have some type of sugar molecule. And that's exactly what our Peptidoglycan is. Peptidoglycan is a polymer of sugar as well as amino acids that create a mesh like structure. Now, each disaccharide within our Peptidoglycan contains several amino acids that basically connect to other amino acids attached to adjacent sugar chain. So, to see exactly what we mean, let's take a look at the following diagram. So, the cell wall is found right outside the inner plasma membrane.
