Is the polar end of the phospholipid plasma membrane hydrophobic or hydrophilic?
The polar end of a phospholipid in the plasma membrane is hydrophilic, meaning it is attracted to water. This hydrophilic end faces outward towards the aqueous environment both inside and outside the cell.
What is the difference between the hydrophilic end and the hydrophilic end of a phospholipid?
The hydrophilic end of a phospholipid, known as the "head," is typically composed of a phosphate group and is attracted to water, making it water-soluble. In contrast, the hydrophobic end, or "tail," consists of long fatty acid chains that repel water, making them water-insoluble. This amphipathic nature allows phospholipids to form bilayers, which are essential for cell membrane structure and function. Thus, the hydrophilic head interacts with the aqueous environment, while the hydrophobic tails orient away from it.
How can a polypeptide have both hydrophilic and hydrophobic properties?
Many organic molecules have an end that will dissolve in fat (this would be the hydrophobic end) and an end that will dissolve in water (this will be the hydrophilic end). As the ends are joined together by the rest of the molecule, the molecule has both properties at once and such molecules are frequently used in the formation of organic membranes.
What group does the polar end of a phospholipid contain?
A phospholipid is a type of fat found in the body. Phospholipids are made up of a polar hydrophilic head and a nonpolar hydrophobic tail. Hydrophilic means water-loving and hydrophobic means water hating.
Which end of a phospholidid is attracted to water?
The hydrophilic head which is made up of a phosphate group and a polar molecule.
Is the polar end of the phospholipid plasma membrane hydrophobic or hydrophilic?
The polar end of a phospholipid in the plasma membrane is hydrophilic, meaning it is attracted to water. This hydrophilic end faces outward towards the aqueous environment both inside and outside the cell.
Which end of the plasma membrane is hydrophilic?
The "head" of the membrane, the phosphate.

Is salt a hydrophilic or hydrophobic?
No. Instead, salt is hydrophilic ("water-loving"). Salt (NaCl, or Na+ and Cl-) is very attracted to Water (H20, or H2+ and O-) because opposite electrostatic charges attract. The anionic ("negatively charged") Chlorine end of the salt molecule is attracted to the 2 cationic ("positively charged") Hydrogen ions of the water molecule: Cl- wants H2+. In the same way, the cationic Sodium end is attracted to the anionic Oxygen end: Na+ wants O-. Since each end of the salt molecule is attracted to the reciprocal end of the water molecule, there is a strong overall molecular attraction.
The polar end of the phospholipid plasma membrane is . hydrophilic hydrophobic?
"philic" ( likes water)
How does soap help to remove dirt?
Soap molecules have a hydrophilic (water-attracting) end and a hydrophobic (water-repelling) end. When soap is mixed with water, the hydrophobic end attaches to dirt and oil, while the hydrophilic end allows them to be rinsed away. This process helps to lift the dirt from surfaces and emulsify it in water for easy removal.

Which end of a phospholidid is attracted to water?
The hydrophilic head which is made up of a phosphate group and a polar molecule.
How does a soap clean a fat stain from clothing?
Soap molecules have one end that is attracted to water (hydrophilic) and another end that is attracted to fats and oils (hydrophobic). When soap is added to a fat stain, the hydrophobic end attaches to the fat molecules, while the hydrophilic end binds to water, allowing the fat molecules to be lifted off the fabric and rinsed away with water.
Are fish scales hydrophilic or hydrophobic?
Hydrophilic
Are carbohydrates hydrophilic or hydrophobic and how do you test this?
Carbohydrates are hydrophilic, meaning they have an affinity for water. To test this, you can perform a simple solubility test: add the carbohydrate sample to water and observe if it dissolves. If it dissolves, it is hydrophilic; if it does not dissolve or forms a separate layer, it is likely hydrophobic.
