Question
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.

Students have asked these similar questions
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.
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
Saturated fatty acids are called "saturated" because they are saturated with what component? C, H, or double bonds?
