Phospholipid bilayer Flashcards
How would you describe the phospholipid bilayer?
- fluid mosaic
- semi-permable
What is the phospholipid bilayer made from?
Two layers of phospholipids
What are the characteristics of phospholipids?
Polar, phosphate, hydrophilic head
Non-polar, fatty acid, hydrophobic tail
What is within the bilayer?
Protiens-
carbohydrates
cholesterol
what does cholesterol do within the bilayer
maintains fluidity
what types of carbohydrates are within the bilayer?
glycoprotiens (carbohydrates on protiens)
Glycolipids (carbohydrates on lipids)
What types of proteins are within the bi layer
Trans membrane (span entire bi layer)
Peripheral (on one side)
what do proteins do within the bilayer?
responsible for transport, signalling and cell to cell recognition
what do carbohydrates do within the bilayer?
Cell recognition and cell to cell adhesion
