Question

Which of the following is TRUE about lipids?

• A. Animal fats ae liquid while plant has solid oils
• B. Animal fats are solid while plant has liquid oils
• C. Animal and plants both have solid fats
• D. Animal and plants both have liquid oils

Answer 1

The correct option is B Animal fats are solid while plant has liquid oils

Both fats and oils are molecules shaped like a capital E with a glycerol spine and arms made of fatty acid chains.

In animals, the carbon atoms in the fatty acids are saturated with hydrogen atoms. This allows them to lie straight and the molecules will pack neatly into a solid arrangement.

In plants, missing hydrogen atoms cause bends in the fatty acids. This reduces the amount of intermolecular bonding that can occur and keeps the fat liquid at room temperature.

So the correct answer is option B.
