Question

phospholipids are a unique lipid because they have both a hydrophilic portion and a hydrophobic portion. this property is referred to as:
○ amphipathic
○ bilayer
○ hybrid
○ triglyceride

Explanation:

To solve this, we analyze each option:

• Amphipathic: A molecule with both hydrophilic (water - attracting) and hydrophobic (water - repelling) regions. Phospholipids have a hydrophilic head and hydrophobic tails, so this matches.
• Bilayer: Refers to the double - layered structure formed by phospholipids in a cell membrane, not the property of having both hydrophilic and hydrophobic parts.
• Hybrid: Does not relate to the chemical property of having both water - attracting and water - repelling regions.
• Triglyceride: A type of lipid composed of glycerol and three fatty acids, and it is not amphipathic (it is mostly hydrophobic).

Answer:

A. Amphipathic
