Actual meaning of hydophilic & hydrophobic components?
Answer:
Hydrophile :
Hydrophile, from the Greek (hydros) "water" and φιλια (philia) "friendship," refers to a physical property of a molecule that can transiently bond with water (H2O) through hydrogen bonding. This is thermodynamically favorable, and makes these molecules soluble not only in water, but also in other polar solvents. There are hydrophilic and hydrophobic parts of the cell membrane.
A hydrophilic molecule or portion of a molecule is one that is typically charge-polarized and capable of hydrogen bonding, enabling it to dissolve more readily in water than in oil or other hydrophobic solvents. Hydrophilic and hydrophobic molecules are also known as polar molecules and nonpolar molecules, respectively.
Soap has a hydrophilic head and a hydrophobic tail which allows it to dissolve in both waters and oils, therefore allowing the soap to clean a surface.
Hydrophobe:
Hydrophobe (from the combining form of water in Attic Greek hydro- and for fear phobos) in chemistry refers to the physical property of a molecule that is repelled from a mass of water.
As a note - oleophobic: (from the Greek (oleo) "oil") refers to the physical property of a molecule that is repelled from a mass of oil
Hydrophobic molecules tend to be non-polar and thus prefer other neutral molecules and nonpolar solvents. Hydrophobic molecules in water often cluster together. Water on hydrophobic surfaces will exhibit a high contact angle.
Examples of hydrophobic molecules include the alkanes, oils, fats, and greasy substances in general. Hydrophobic materials are used for oil removal from water, the management of oil spills, and chemical separation processes to remove non-polar from polar compounds.
Hydrophobic is often used interchangeably with "lipophilic". However, the two terms are not synonymous. While hydrophobic substances are usually lipophilic, there are exceptions — the silicones, for instance.
hydrophilic .which attracts water or is attracted to water
hydrophobic..the opposite
likes water and doesn't like water
Hydro means water &philic means to love &phobic comes from the word phobia which means to fear or hate . therefore hydrophilic means to love water &hydrophobic means to hate water.
v simple...
hyro= water
phobia= fear
philia= love
so, hydro+phobic= water fearing=water reppelling
& hyro+philic= water loving= water attracting
Wow, some people make this so complicated. To keep the difference straight, think of related words you will actually remember, like arachnophobia (fear of spiders) and Philadelphia (the city of "brotherly love"). Then remember that molecules (and virii and bacteria, and many other things you may learn about in the future) have "loves" and "fears" just like humans do, in this case, water ([hydro]gen dioxide).
And because this probably relates to the lipid bilayer of cell membranes, remember that water is outside & inside the cell, so the balloon shaped hydrophilic "heads" love to stay and float out on the water, while the hydrophobic "tails" hide safe inside (if they can). This would be a typical textbook cartoon ("artist's interpretation") of what a cross section of a cell's lipid bilayer might look like

The big purple Grimace-looking blobs are supposed to be proteins, but the things we're concerned with are the orange looking balloons that each have two tails and are covering the whole picture. (you can ignore the actual words "hydrophobic" & "hydrophilic" in this picture as they are not referring to the phospholipid molecules)
And here's a simple 3D model representing only the phospholipids

And another cartoon of a single phospholipid with the correct "hydro" labels

Hope this helps.
