Question

which type of lipid is more likely solid at room temperature?
saturated
unsaturated

Explanation:

Saturated fatty acids have straight hydrocarbon chains that allow them to pack tightly together. This tight - packing results in stronger intermolecular forces, which leads to a higher melting point. Unsaturated fatty acids have kinks in their chains due to double bonds, preventing tight packing and resulting in lower melting points. So, saturated lipids are more likely to be solid at room temperature.

Answer:

saturated
