  • What are lipids?

    Lipids are fats and fat-like molecules important for energy storage and cell membrane structure.
  • What is the fatty acid tail in a lipid?

    The fatty acid tail is the hydrophobic (water-repelling) part of a lipid molecule.
  • What is a phospholipid?

    A phospholipid is a lipid with a hydrophilic (water-attracting) head and hydrophobic tails.
  • What is a bilayer in cell membranes?

    A bilayer is two layers of phospholipids arranged with hydrophobic tails inward and hydrophilic heads outward.
  • What are triglycerides?

    Triglycerides are lipids used for long-term energy storage in organisms.
  • What role do phospholipids play in cells?

    Phospholipids form the structural basis of cell membranes, creating a selective barrier.
