Question

In order for a polar compound to enter into the hydrophobic space of the phospholipid tails, it would need to break the many __________ bonds it has formed with the water and enter into a space where these bonds cannot form. Therefore, it is not a repelling action but a "lack of attraction.

Answer 1

Answer:

In order for a polar compound to enter into the hydrophobic space of the phospholipid tails, it would need to break the many polar covalent bonds bonds it has formed with the water and enter into a space where these bonds cannot form. Therefore, it is not a repelling action but a "lack of attraction".

Explanation:

Water as polar solvent and the phospholipids:

Water is very different on the molecular and that is due to the more polar nature, which is caused by the hydrogen bonding with in a H₂0 molecule. As the water molecules forms bonds with the other molecules in a specific formation of unequal polarities on its molecules. As the molecules have an unequal amount of charges present on it. For, the phospholipids they have two hydrophobic tails and the hydrophilic head. Through which they form most of the cell membrane structures.

In order to add any polar molecule to the hydrophilic head of the phospholipid there are many covalent bonds which are required to be broken, as these bonds include the covalent bonds found inside the molecular level. While, the hydrophobic tails of the molecules can't arrange themselves to form the bonds with the polar molecules more frequently.

Answer 2

In order for a polar compound to enter into the hydrophobic space of the phospholipid tails, it would need to break the many HYDROGEN bonds it has formed with the water.

The cell membrane is a lipid bilayer, which is mainly composed of phospholipids. A phospholipid is a molecule composed of a polar phosphate head and two non-polar fatty acid chains.

In the lipid bilayer, phospholipids are arranged so their hydrophilic phosphate heads face outward in contact with water (and other molecules), both inside and outside the cell.

In consequence, phospholipidic phosphate heads form hydrogen bonds with water on both surfaces (exterior and interior) of the cell.

Conversely, the fatty acid tails of phospholipids are hydrophobic and thereby they face inside the lipid bilayer, facing and interacting with each other.

In conclusion, in order for a polar compound to enter into the hydrophobic space of the phospholipid tails, it would need to break the many HYDROGEN bonds it has formed with the water.
