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.
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.
glycerin was polar. One day it became non polar. So it depends upon time!!
Yes, a molecule can exhibit both polar and non-polar characteristics depending on its structure. For example, in a large molecule with both polar functional groups (like -OH) and non-polar hydrocarbon chains, the overall polarity can vary. If the non-polar regions dominate, the molecule may behave as non-polar, while the presence of polar regions can impart some polar characteristics. This duality is often seen in amphipathic molecules, like phospholipids, which have both hydrophilic and hydrophobic parts.
Most lipids are nonpolar molecules due to their hydrophobic nature, meaning they do not mix well with water. However, some lipids, suchjson as phospholipids, have polar regions (like the phosphate head) and nonpolar regions (like the fatty acid tails), making them amphipathic.
An example of a lipid bilayer is the cell membrane. It is formed by two layers of phospholipids, which have a polar head and non polar tails, providing an anfoteric environment in which phospholipids arrange to form a membrane.

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.

No, non-polar molecules are hydrophobic because they cannot form hydrogen bonds. A good example of this would be a cell membrane. The fatty acids in the lipid bilayer are non-polar and hydrophobic, while the polar ends that face the outside and inside of the cell are hydrophilic.

Glycerophospholipid is more soluble in water because it contains both polar and non polar regions, which allow them interact with polar and non polar substance. The ionized alcohol and phosphate portion is polar and strongly attracted to water.
The head (or top) of a phospholipid is polar and the carbon chain tail is non-polar.
Yes, Since the lipid bilayer of cells is nonpolar, only non-polar substances can pass directly through the bilayer without the need for any help by membrane transport proteins.

Non-polar- both atoms have the same electronegativity as they are both chlorine!
