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

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

the increase of protons   hope this

thats a little if u want the answer just look it up on google thats what i do haha : )
