Question
1. A phospholipid has a "head" made up of a glycerol molecule attached to a single Blank, which is attached to another small molecule.target 1 of 5
2. Phospholipids vary in the small molecules attached to the phosphate group. The phospholipid shown in the figure has a Blank attached to phosphate.target 2 of 5
3. Because the phosphate group and its attachments are either charged or polar, the phospholipid head is Blank, which means it has an affinity for water.target 3 of 5
4. A phospholipid also has two "tails" made up of two Blankmolecules, which consist of a carboxyl group with a long hydrocarbon chain attached.target 4 of 5
5. Because the C-H bonds in the fatty acid tails are relatively nonpolar, the phospholipid tails are Blank, which means they are excluded from water.

1. A phospholipid has a "head" made up of a glycerol molecule attached to a single **phosphate**, which is attached to another small molecule.
2. Phospholipids vary in the small molecules attached to the phosphate group. The phospholipid shown in the figure has a **choline** attached to phosphate.
3. Because the phosphate group and its attachments are either charged or polar, the phospholipid head is **hydrophilic**, which means it has an affinity for water.
4. A phospholipid also has two "tails" made up of two **fatty acid** molecules, which consist of a carboxyl group with a long hydrocarbon chain attached.
5. Because the C-H bonds in the fatty acid tails are relatively nonpolar, the phospholipid tails are **hydrophobic**, which means they are excluded from water.
