Question

fats and oils are similar molecules. what is the distinction between the terms?
select the correct answer below:
oils are fats that are liquid at room temperature.
oils are fats that are solid at room temperature.
oils contain fatty acids bonded to long - chain alcohols; in fats, the fatty acids are bonded to glycerol.
oils contain two fatty acid chains rather than three, like fats.

Explanation:

Fats and oils are both triglycerides (three - fatty - acid chains bonded to glycerol). The main physical difference is their state at room temperature. Oils are liquid at room temperature, while fats are solid. Option 2 is incorrect as it misstates the physical state. Option 3 is wrong because both fats and oils have fatty acids bonded to glycerol. Option 4 is incorrect as both fats and oils are triglycerides (three fatty - acid chains).

Answer:

Oils are fats that are liquid at room temperature.
