May 14, 2018  · Amphipathic Structure. Lipids that form cellular membranes are usually amphipathic. This means that one end of each lipid molecule is attracted to water and the other repels water. When submerged in water like they are in living cells, this property automatically forces the lipids into an alignment that creates a natural water barrier.

Dec 20, 2018  · The chemical nature of the fatty acids contained within the lipid determines its physical characteristics. For instance, a fatty acid that is saturated with as many hydrogen atoms as it can hold is solid at room temperature, while unsaturated fatty acids are liquid.
