Question

The two ends of a fatty acid molecule have different properties; the hydrocarbon chain is hydrophobic, whereas the carboxyl group is hydrophilic. Molecules having both properties are called:

1) amphipathic
2) saturated
3) unsaturated
4) polyunsaturated

Answer 1

An amphipathic molecule contains both a hydrophilic and a hydrophobic region. Fatty acids exhibit both properties, making them amphipathic.

Step-by-step explanation:

An amphipathic molecule contains both a hydrophilic and a hydrophobic region. In the case of a fatty acid molecule, the hydrocarbon chain is hydrophobic, while the carboxyl group is hydrophilic. Therefore, molecules having both properties, such as fatty acids, are called amphipathic.
