Question
What is the nature of lipid bilayer?
- Hydrophilic nature
- Hydrophobic nature
- Hydrophilic and hydrophobic nature
- It depends on surrounding medium
Hint:
The lipid component consists of two parts with different properties.
The correct answer is: Hydrophilic and hydrophobic nature
- The lipid bilayer is both hydrophobic and hydrophilic in nature.
- Our cells consist of a cell membrane that surrounds the cytoplasm and protects its inner content. It also allows the movement of certain substances across it due to its semi-permeable nature.
- It is composed of a lipid bilayer with proteins embedded in it and carbohydrates attached through it. The lipid bilayer consists of lipid molecules that have two parts, one head, and one tail. The head part is composed of glycerol attached to the phosphate group that makes it hydrophilic in nature and the tail Is composed of carbon and hydrogen compounds that make it hydrophilic in nature. Thus, we can say that a cell membrane possesses both these properties.
Hydrophilic refers to water-loving and hydrophobic refers to water-hating.
