Substances are hydrophobic because they are nonpolar. Nonpolar molecules are made up of elements with little difference in their electronegativities so they do not have charges or partial charges. Water is a polar molecule so it tends to be attracted to other molecules that are polar as well. This is often summed up as "like attracts like".
Some examples of hydrophobic molecules include fats and oils which are nonpolar because they have large hydrophobic hydrocarbon chains.
No. Hydrophobic is a concept or symptom, not a substance as lipids are.
A hydrophilic substance will dissolve in water. A hydroPHOBIC substance will not.
A term that may be used to describe a substance that is hydrophobic is non polar. Non polar things are repelled by water.
A large hydrophobic protein.
The substance that forms the hydrophobic tail on the back end of a phospholipid are fatty acids. Phospholipids are not "true fats" as they have a phosphate group that replaces one of the fatty acids
No. Hydrophobic is a concept or symptom, not a substance as lipids are.
All substances that are water repelling are considered hydrophobic substances. Ex: Oil, Waxes, etc..
A hydrophilic substance will dissolve in water. A hydroPHOBIC substance will not.
nope acids are hydophilic.
Hydrophobic.
A term that may be used to describe a substance that is hydrophobic is non polar. Non polar things are repelled by water.
It has a harder time passing through. The inside of the membrane is hydrophobic, so something hydrophilic (water-loving), will not be liked by the hydrophobic (water-fearing) membrane.
It depends on the physical properties of the substance. Sometimes heating a hydrophobic substance can increase solubility. Also, heating may cause the substance to denature and dissolve. In the case of proteins, proteins can contain many hydrophobic parts but still be soluble in water. However, hydrophobic substances do not typically dissolve in water, due to the polar nature of water. Typically, scientists use the word "hydrophobic" only to describe substances that have a negligible solubility in water. You may have meant to ask "why do hydrophilic substances dissolve in water".
A large hydrophobic protein.
Hydrophilic means that a substance has an affinity for/attraction to water. It binds with water easily. [It is the opposite of hydrophobic, where a substance has an aversion for water. It forms droplets in water (like oil).]
The substance that forms the hydrophobic tail on the back end of a phospholipid are fatty acids. Phospholipids are not "true fats" as they have a phosphate group that replaces one of the fatty acids
No. Hydrophobic literally means "afraid of water," so they will repel each other, most likely because the other substance is non-polar.
