- glycerol and phospholipids
- heads and tail cartoon and membrane phospholipids
- condensation reactions and synthesis of membrane phospholipids
- membrane fluidity and cell function
- length of fatty acid chains in phospholipids and membrane fluidity
- saturation of fatty acid chains in phospholipids and membrane fluidity
- amphipathic nature of cholesterol and its ability to interact with membrane phospholipids
- lipid rafts and membrane fluidity
- ether linkages in phospholipids and response to acidic conditions
- ester linkages in phospholipids and response to acidic conditions
- strong detergent such as SDS and membrane proteins
- weak detergent such as Triton X-100 and membrane proteins
- detergents and their effect on lipid bilayers
Explanation / Answer
Glycerol and phospholipids – Structural relationship: the glycerol is the constituent of Phopholipid.
- Heads and tail cartoon and membrane phospholipids - Structural relationship: the head and tail are the hydrophobic and hydrophilic regions of phospholipid. These represent the structural characterstics of phospholipid.
- Condensation reactions and synthesis of membrane phospholipids – Contrary relationship: both processes are opposite to each other.
- Membrane fluidity and cell function: complementary relationship: Fluidity provide cell to function according the requirement.
Length of fatty acid chains in phospholipids and membrane fluidity – the invert proportional relationship; lesser the length higher the flexibility in the fluidity.
- Saturation of fatty acid chains in phospholipids and membrane fluidity: Invert proportional relationship: saturated fatty acid provides straight and stiff fatty acid. Therefore, unsaturated fatty acid most prefer.
- amphipathic nature of cholesterol and its ability to interact with membrane phospholipids: Positive relationship: More it contact with phospholipid causes more increase in rigidity of the membrane.
