Show answer and explanation
Correct answer: A hydrocarbon chain with a terminal carboxyl group
Fatty acids consist of a long hydrocarbon chain (typically 12–20 carbons) with a terminal carboxyl group (–COOH). The hydrocarbon tail is hydrophobic, while the carboxyl head is weakly acidic and hydrophilic. This structure underlies their role in energy storage and membrane composition.
