Concept explainers
The fatty acid composition of three triacylglycerols (A, B, and C) is reported below. Predict which one has the highest melting point. Which one do you expect to be liquid (oil) at room temperature? Explain.
Interpretation:
The triacylglycerols with highest melting point and fatty acid expected to be liquid at room temperature has to be identified.
Concept Introduction:
Triacylglycerol:
It is also known as triglyceride, an ester composed of glycerol and long chains of acyl fatty acids.
Explanation of Solution
The fatty acid composition A has the highest melting point and B and C are expected to be at low melting point.
Since the composition A contains
The triacylglycerols with highest melting point and fatty acid expected to be liquid at room temperature was identified.
