Moving to the next question prevents changes to this answer Question 2 of 10 Question 2 1 points Save Answer Which of the following will have lowest Tm? Membranes made up of pure phospholipids comprising 16C long unsaturated Fatty acids O Membranes made up of pure phospholipids comprising 16C long saturated Fatty acids Membranes made up of pure phospholipids comprising 14C long saturated Fatty acids O Membranes made up of pure phospholipids comprising 18C long unsaturated Fatty acids > Moving to the next question prevents changes to this answer. a estion 2 of 10Explanation / Answer
Melting temperature is the phase transition temperature from solid to fluid like state.
Longer chains have more interactions and hence more melting temperature.
Presence of kinks in unsaturated fatty acids make them irregular and less orderly.
As a result, melting temperatures of lipids with saturated fatty acids is higher than unsaturated
fatty acids.
Hence option a is the correct answer.
