Study Notes
Glycocalyx Composition
- Composed primarily of polysaccharides and polypeptides, forming a sticky outer layer on cells.
- Consists of glycoproteins and glycolipids, contributing to its structure and functions.
Primary Function
- Acts as a protective barrier for cells, shielding them from mechanical and chemical damage.
Location
- Located on the external surface of the plasma membrane, overlying the cell wall in prokaryotic cells or directly on eukaryotic cells.
Cell Interactions
- Plays a critical role in facilitating cell-cell recognition and interaction, essential for immune response and tissue formation.
Nature
- Typically a fuzzy, viscous layer, aiding in cellular communication and protection.
Protective Mechanism
- Provides a physical barrier against pathogens, preventing their entry and invasion into cells.
Role in Cell Signaling
- Involved in the binding of signaling molecules, enhancing communication between cells and their environment.
Advantages of Composition
- Polysaccharides and polypeptides offer flexibility and resilience, enabling adaptation to various environments and interactions.
Adhesion Contribution
- Enhances cell adhesion to surfaces and other cells through specific molecular interactions, promoting tissue integrity and functionality.
Consequences of Damage
- Damage or impairment of the glycocalyx can lead to increased susceptibility to infections, inflammation, and impaired cell signaling, ultimately affecting cellular health.
