Drag the terms on the left to the appropriate blanks on the right to complete the sentences. A phospholipid has a "head" made up of a glycerol molecule attached to a single, which is attached to another small molecule. Phospholipids vary in the small molecules attached to the phosphate group. The phospholipid show in the figure has a attached to phosphate. Because the phosphate group and its attachments are either charged or polar, the phospholipid head is, which means it has an affinity for water. A phospholipid also has two "tails" made up of two molecules, which consist of a carboxyl group with a long hydrocarbon chain attached. Because the C - H bonds in the fatty acid tails are relatively nonpolar, the phospholipid tails are, which means they are excluded from water.
