What Is The Function Of Muramic Acid And Peptidoglycan In Cell Wall Of Blue Green Algae?

Muramic acid is a component of peptidoglycan  present in form of N-acetyl muramic acid in the cell wall of blue green algae. Basic functions of peptidoglycan layer in cell wall is to:

• provide tensile strength and support to the cell wall.
• protect the cell from the action of harmful chemicals (antibiotics)
• allow sufficient transport of nutrient and metabolites.
