Which compound is missing four or more hydrogen atoms?
A)Monounsaturated fatty acid
B)Polyunsaturated fatty acid
C)Long-chain saturated fatty acid
D)Short-chain saturated fatty acid
E)Triglycerides

Question

Quizplus · Accepted Answer

Polyunsaturated fatty acids have multiple double bonds in the carbon chain, meaning that they are missing at least four or more hydrogen atoms compared to a fully saturated fatty acid. Monounsaturated fatty acids have only one double bond, meaning they are missing only two hydrogen atoms. Long-chain and short-chain saturated fatty acids have no double bonds, therefore are missing zero hydrogen atoms compared to a fully saturated fatty acid. Triglycerides are glycerol molecules with three fatty acid chains attached, so they do not directly relate to the number of missing hydrogen atoms.
