Question

question 4 - 1 point
identify the hydrophilic region in this structure.

select the correct answer below:

both of the above
none of the above

Explanation:

Hydrophilic regions are polar or charged and interact well with water. The \(H_3N^+ - CH_2CH_2 - O - \overset{O}{\overset{||}{P}} - O - CH_2\) part has a charged \(N\) (from \(H_3N^+\)) and polar \(P - O\) bonds. The hydrocarbon chains (the zig - zag lines) are non - polar (hydrophobic).

Answer:

The second option (\(H_3N^+ - CH_2CH_2 - O - \overset{O}{\overset{||}{P}} - O - CH_2\)) is the hydrophilic region.
