Lipids are _______.

Explanation:
Lipids are hydrophobic because they are built mainly from nonpolar carbon-hydrogen bonds, making them insoluble in water. Water is polar, so it energetically favors hydrogen-bonding with itself rather than with these nonpolar molecules, causing lipids to aggregate and form separate, nonpolar phases like fat droplets. While some lipids, such as phospholipids, are amphipathic with both nonpolar tails and polar heads, the general property of lipids as a class is hydrophobic, which is why hydrophilic or polar would not describe them as a whole. Amphipathic describes specific lipid types, not all lipids.
