Answer:
Hydrophillic head and a hydrophobic tail
Explanation:
Every fatty acid is composed of long chain of hydrocarbon tail. This hydrocarbon tail is nonpolar and insoluble in water. Hence this tail is labeled 'hydrophobic'.
However, the head of the fatty acid contains polar COOH group which is capable of interacting with water, hence the head is hydrophillic.
Hence, a fatty acid is composed of a hydrophillic head and a hydrophobic tail.
