What does it mean when a lipid is non-polar?
There isn't exactly something known as a non-polar lipid. A lipid consists of a polar phosphate 'head' and a non-polar hydrocarbon 'tail'. When something is 'polar', it means that that the charges between a compound aren't shared equally. For example, in water (H2O), H has a slightly positive charge while O has a slightly negative charge. Since the 'head' of the lipid is polar, it attracts H2O molecules and so it is hydrophilic. On the other hand, the 'tail' of the lipid is non-polar, hence it is hydrophobic.
What example of a lipid which is both polar and non polar?
A type of lipid molecule with polar and non polar regions are phospholipids. Phospholipids are a class of lipids that are a major component of all cell membranes as they can form lipid bilayers.
Is the glycerol head of a lipid is polar or nonpolar?
glycerin was polar. One day it became non polar. So it depends upon time!!
Is cell membrane a lipid?
Yes, the cell membrane is made out of a type of lipid called phospholipids. These have a phosphate group and a lipid tail. The phosphate head is polar and water-loving, the lipid tail is non-polar and hydrophobic (water-hating).
Are lipids polar?
Lipids, both fats and oils, have a polar head and a non-polar tail.
Is a polar head a lipid or a protein or a carbohydrate?
Lipid

What can you conclude from the level of lipid solubility in organic solvents?
Another term for organic solvent is non polar solvent, because it dissolves non polar molecules. A lipid is also a fatty acid as it contains both a charged polar 'head' and a non polar 'tail'. This polar head will tend to interfere with the tail's dissolving in organic solvents, so the longer the non polar tail [to overcome this] of a lipid the greater its solubility.
Why is a lipid bilayer incellmembrane considered as a barrier to the diffusion of polar molecules?
Polar molecules are hydrophilic in nature. They tend to repel from the lipid content and would easily adhere or mix with the water molecules. A lipid bi-layer consists of lipids and so it would not allow the polar molecules to pass through.

Which macromolecules are insoluble in water but dissolvable non polar solvents?
lipid
Can non polar molecules cross the lipid bi layer easily?
no
What is the most common bond in a lipid?
a non-polar covalent bond
What prevents lipid from mixing water?
Water is polar, but lipids are nonpolar.
