Study Notes
Cell Recognition
- Cells identify one another through specific binding to surface molecules on the plasma membrane.
- These surface molecules often include carbohydrates that extend outside the cell.
Membrane Carbohydrates
- Membrane carbohydrates can be attached to lipids, creating structures known as glycolipids.
- More frequently, carbohydrates are attached to proteins, resulting in glycoproteins.
Variation in Carbohydrates
- The composition of carbohydrates on the extracellular side of the plasma membrane differs across species.
- Within a single individual, the carbohydrate types can vary between different cell types.
- This variability plays a crucial role in cellular recognition and interaction.
