Detailed explanation-2: -Steroids are another class of lipid molecules, identifiable by their structure of four fused rings. Although they do not resemble the other lipids structurally, steroids are included in lipid category because they are also hydrophobic and insoluble in water.
Detailed explanation-3: -The many C-C and C-H bonds make fats nonpolar and insoluble in water.
Detailed explanation-4: -Although glucose can be more concentrated outside of a cell, it cannot cross the lipid bilayer via simple diffusion because it is both large and polar, and therefore, repelled by the phospholipid membrane.
