The plasma membrane and other membranes of a cell are composed mostly of proteins and a type of lipid called phospholipids. A phospholipids molecule is structured with two fatty acids. The two fatty acids at one end (the tail) of the phospholipids are hydrophobic (not attracted to water). The other end (the head) of the molecule includes a phosphate group, which is negatively charged and hydrophilic (attracted to water). Thus, the tail end of a phospholipids is pushed away by water, while the head is attracted to water.

A double layer of phospholipids makes up the plasma membrane.


How are phospholipids oriented in the plasma membrane and what role does this orientation play in the structure and function of the membrane?

Phospholipids in the plasma membrane are arranged in a bilayer, with the hydrophilic heads facing outward towards the watery environment and the hydrophobic tails facing inward. This orientation helps maintain the integrity and fluidity of the membrane, allowing it to selectively control the movement of substances in and out of the cell.

The plasma membrane contains two kinds of lipids?

Phospholipids. They feature a phosphate group at one end of each molecule. The heads, or phosphate ends, are hydophilic ("water-loving") and the tails are hydrophobic ("water-fearing"), which keeps them oriented correctly, with the tail ends always inside the lipid layer.


Are peripheral steroids part of plasma membrane?

No, peripheral steroids are not part of the plasma membrane. Peripheral steroids are molecules found in the cytoplasm and do not directly interact with the plasma membrane. The plasma membrane is primarily composed of phospholipids, proteins, and cholesterol.
