Which of the following statements regarding saturated fatty acids is true?
A
Saturated fatty acids are more prone to oxidation than unsaturated fatty acids.
B
Saturated fatty acids contain one or more double bonds in their hydrocarbon chain.
C
Saturated fatty acids are typically liquid at room temperature.
D
Saturated fatty acids have no double bonds between carbon atoms in their hydrocarbon chain.
Verified step by step guidance1
Understand the structure of saturated fatty acids: Saturated fatty acids are composed of long hydrocarbon chains with no double bonds between the carbon atoms. This means all carbon-carbon bonds are single bonds.
Compare with unsaturated fatty acids: Unsaturated fatty acids contain one or more double bonds in their hydrocarbon chains, which introduces kinks and affects their physical properties.
Consider the oxidation tendency: Double bonds in unsaturated fatty acids make them more prone to oxidation compared to saturated fatty acids, which lack these double bonds.
Analyze physical state at room temperature: Saturated fatty acids, due to their straight chains, can pack closely together, making them solid at room temperature, unlike unsaturated fatty acids which are typically liquid.
Identify the correct statement: Based on the above analysis, the statement 'Saturated fatty acids have no double bonds between carbon atoms in their hydrocarbon chain' is true, as it accurately describes the structure of saturated fatty acids.
