The plasma membrane surrounds the cell. Chemically plasma membrane is composed of: (a) Protein: 60 to 80% (b) Phospholipids: 20 to 40% (e) Cholesterol in small amount (d) Carbohydiutes in small amount Different models were put forward about the physiochemical nature of plasma membrane.
Proteins are polymers of .amino acids. The name of proteins is derived from the Greek word called prokios. It means first place. Proteins always contain atoms of carbon, hydrogen, nitrogen. oxygen, and sometimes sulfur. Proteins are composed of more than 50% of the dry
