Are saturated or unsaturated fats generally solids at room temperature? Explain why there is a difference in the fluidity
of these two related molecules
What will be an ideal response?
ANSWER: Saturated fats are generally solids at room temperature. Saturated long chain fatty acids are
straight, and can pack tightly together. However, unsaturated fats have double bonds that
kink the long carbon chains, creating more disorder and preventing them from packing
together like the saturated fats.
