Definition, Meaning & Synonyms
murein
noun
/ˈmjʊəraɪn/

Definition
Murein is a polymer consisting of glycan strands cross-linked by peptides, forming a crucial component of bacterial cell walls.

Examples
- The murein layer in Gram-positive bacteria is thick and retains the crystal violet stain used in the Gram staining procedure.
- Antibiotics like penicillin target the synthesis of murein, weakening bacterial cell walls and leading to cell lysis.
- Researchers study murein to develop new antibacterial therapies that can combat resistant strains of bacteria.

Meaning
It helps maintain the structure and integrity of bacterial cells by providing rigidity and protection against environmental stress.

Synonyms
- peptidoglycan
- cell wall (in the context of bacteria)
