Question

For lipids to be fluid at room temperature, they should have ________. For lipids to be fluid at room temperature, they should have ________. a higher number of glycerol molecules a higher number of cis double bonds a longer carbon chain single bonds only

Answer 1

Answer:

a higher number of cis double bonds

Explanation:

Linear lipids without the cis double bonds align very well with each other. For these lipids, the surface area in contact with one another is maximized, which maximizes the London dispersion forces between the carbon chains and causes them to be solid at room temperature.

The cis double bonds introduce a bend in the chain, making it crooked instead of linear and making alignment of the carbon chain more difficult. Thus, the intermolecular forces between the chains are weaker and these lipids are liquid at room temperature
