BIOCHM-CLVKAN

Which of the following triacylglycerols (TAGs) would have the highest melting point?

A

A TAG composed of two 24-carbon saturated fatty acids and a 20-carbon fatty acid with a single trans-double bond.

B

A TAG composed of two 20-carbon saturated fatty acids and a 24-carbon fatty acid with a single trans-double bond.

C

A TAG composed of two 24-carbon saturated fatty acids and a 20-carbon fatty acid with two cis-double bonds.

D

A TAG composed of one 24-carbon saturated fatty acid and two 20-carbon fatty acid one with a single trans-double bond and one with a single cis-double bond..

E

A TAG composed of three 20-carbon unsaturated fatty acids each with a single trans-double bond.

F

All of the above will have the same melting point.
