Therefore, accurately monitoring GSH variations is critical for understanding liver injury mechanisms, early diagnosis, and treatment evaluation.

Furthermore, molecules possessing multiple aromatic rings or large, flexible, rotatable moieties were found to exhibit enhanced sensitivity to viscosity due to increased frictional interactions in solutions.
