Of the Following, Which Would Contain the Largest Amount of Fatty

Question

Of the following, which would contain the largest amount of fatty acids with trans double bonds?
A) the fatty acid on carbon #1 of the glycerol of phosphatidylcholine
B) butter
C) canola oil
D) the 2 lb, 99 cent package of cookies containing partially hydrogenated cottonseed and/or soybean oil that you consumed with 3 (or more) cups of coffee while studying last night (or early this morning)
E) none of the above would have very much trans-double bond containing fatty acids

Accepted Answer

The 2 lb, 99 cent package of cookies containing partially hydrogenated cottonseed and/or soybean oil would contain the largest amount of trans-double bond containing fatty acids. Partial hydrogenation is a process that converts liquid vegetable oils into semi-solid or solid fats and creates trans-fatty acids. Butter and canola oil contain some naturally occurring trans-fatty acids, but the amount is much smaller compared to partially hydrogenated oils. The specific fatty acid on carbon #1 of the glycerol of phosphatidylcholine cannot be determined without additional information.
