Question
Which of the following statements concerning saturated lipids, eg fatty acids, is not true?Group of answer choicesThey are one of several factors that contribute to atherosclerosis.They generally solidify at room temperature.They are more common in animals than in plants.They contain more hydrogen than unsaturated fats having the same number of carbon atoms.They have multiple double bonds in the carbon chains of their fatty acids.
Solution
The statement that is not true concerning saturated lipids, eg fatty acids, is "They have multiple double bonds in the carbon chains of their fatty acids."
Saturated fats are fats that have all single bonds between the carbons in their fatty acid chains. This means they are "saturated" with hydrogen atoms. On the other hand, unsaturated fats have one or more double bonds in their fatty acid chains, which means they have fewer hydrogen atoms. Therefore, the statement that saturated fats have multiple double bonds is incorrect.
