Question

solid fats usually have a high proportion of _______ fatty acids.
unsaturated
saturated
polyunsaturated
monounsaturated

Explanation:

Saturated fatty acids have no double bonds in their carbon - chain structure. This allows them to pack closely together, resulting in a more solid structure at room temperature. Unsaturated (including polyunsaturated and monounsaturated) fatty acids have double bonds which introduce kinks in the carbon chain, preventing close packing and making them more likely to be liquid at room temperature.

Answer:

B. saturated
