The lipid molecules that contain phosphate groups and commonly form amphipathic membrane components are __________.

### Why this is right Phospholipids contain phosphate groups and commonly have both polar and hydrophobic regions. This amphipathic structure makes them suited to biological membranes. ### The concept In a membrane, polar groups can face watery environments while nonpolar chains are sheltered from water. The word phospholipid identifies phosphate-containing lipids, although phospholipids include more than one structural subtype. ### Terms - **Hydrophobic**: tending to avoid contact with water. - **Polar**: having an uneven distribution of electrical charge. ### Remember Phosphate-containing membrane lipids are often amphipathic.
