Question

Quizplus · Accepted Answer

Fats that are solid at room temperature contain a higher proportion of saturated fatty acids, which have no double bonds between carbon atoms and are able to pack closely together, resulting in a solid state. Unsaturated fatty acids, on the other hand, have one or more double bonds between carbon atoms, which create kinks in the carbon chain and prevent tight packing, resulting in a liquid state at room temperature.
