Question

multiple choice question
which of the following describes how the phospholipid tails interact with water?

hydrophobic
hydrophilic
amphipathic
neutral

Explanation:

Phospholipid tails are nonpolar fatty acid chains, which repel and do not interact favorably with polar water molecules—this is the definition of hydrophobic. Hydrophilic refers to water-attracting (true of phospholipid heads, not tails), amphipathic describes the entire phospholipid (having both water-attracting and water-repelling regions), and neutral does not accurately describe their water-interaction behavior.

Answer:

Hydrophobic
