Which of the Following is NOT Correctly Paired

Question

Which of the following is NOT correctly paired?
A) organic osmolytes and compatible solutes
B) counteracting solute and TMAO
C) methylamine and proline
D) carbohydrate and myo-inositol
E) none of these.

Accepted Answer

Methylamines (such as TMAO) and proline are both types of organic osmolytes, but they belong to different categories. Methylamines are known for their role in counteracting the effects of urea and stabilizing proteins, while proline is a compatible solute that helps in osmoregulation but they are not directly paired as a counteracting solute relationship like TMAO with urea.
