Question

Which chemical property is shared by all types of lipids forming the plasma membrane?

• A. Sugar component
• B. Glycerol backbone
• C. Phosphate group
• D. Hydrophobic region

Answer 1

The correct option is D Hydrophobic region

Lipids are usually amphipathic i.e., one end is hydrophilic (attracts water) and another end is hydrophobic (repels water ). They show a unique behaviour with water, they spontaneously form ordered molecular aggregates, with their hydrophilic ends on the outside, in contact with the water and their hydrophobic parts on the inside, shielded from the water. This property is key to their role as the fundamental components of cellular and organelle membranes.

So,the correct answer is " Hydrophpbic region ".
