Which fats are solid at room temperature and mostly come from animal sources?

• A. Unsaturated fats
• B. Saturated fats
• C. Trans fats
• D. Monounsaturated fats

Answer: (B)

Saturated fats have no double bonds in their fatty acid chains, so the molecules pack tightly and are solid at room temperature. They’re predominantly found in animal fats like butter, lard, and fatty meats. In contrast, unsaturated fats have one or more double bonds, which cause kinks that keep them liquid at room temperature, and trans fats are mostly industrially produced and not primarily from animal sources. So the fats that are solid at room temperature and come mostly from animal sources are saturated fats.
