Peptidoglycan | Peptidoglycan structure | Biochemistry

This video explains about Peptidoglycan and structure of peptidoglycan.

Peptidoglycan is made up of NAM (N-acetyl Muramic acid) and NAG (N-acetyle Glucosamine) linked with Beta 1 4 glycosidic bond.
Peptidoglycan is heteropolysaccharide and Peptidoglycan is found in cell wall of bacteria so it is call structural polysaccharide.

Peptidoglycan is 3D mesh like structure having pentaglycine interbridge. Pentaglycine interbridge is formed by an enzyme called D D Transpeptidase. Penicillin binds to Transpeptidase enzyme and blocks its activity hence the cellwall systhesis is inhibited and bacteria die.
