Chapter 3, Problem 7SQ
Summary Introduction
To examine: Whether the statement “Unlike saturated fats, all unsaturated fats are beneficial to health because their fatty acid tails kink and do not pack together” is true or false.
Concept introduction: Fat is made of two compounds: glycerol and fatty acids. Fats are of two types: saturated fats and unsaturated fats. Unsaturated fats have fatty acids that have at least one double bond between the carbon atoms in their aliphatic chain, thus making them highly reactive.

Is this statement true or false? Unlike saturated fats, allunsaturated fats are beneficial to health because theirfatty acid tails kink and do not pack together.
Most animal fats are solid at room temperature, whereas plant and fish oils tend to be liquid. Both contain fatty acids. Can you predict which type of fat contains saturated fatty acids, and which type contains unsaturated fatty acids?
When natural monounsaturated fats generally undergo the chemical
process of partial hydrogenation, their fatty acid chains are converted into
the following two forms: trans and saturated.
O True
False
