Final answer:
Saturated triglycerides contain single bonds and are solids at room temperature, while unsaturated triglycerides contain double bonds and are liquids at room temperature.
Step-by-step explanation:
Saturated triglycerides contain single bonds and are solids at room temperature, while unsaturated triglycerides contain double bonds and are liquids at room temperature. Saturated fatty acids have no double carbon bonds, which allows them to pack tightly together and form a solid or semi-solid state at room temperature. In contrast, unsaturated fatty acids have double bonds, which introduce kinks in the carbon chain and prevent tight packing, resulting in a liquid state.
