The discrepancies between experiment and theory throughout the long history of vitamin B12 research are caused by the significant influence of the pseudo-Jahn-Teller effect on its biochemical processes, which cannot be accounted for by either the standard density functional theory (DFT) method [88] or the QM-DFT approximation used in most quantum mechanics/molecular mechanics (QM/MM) studies [2, 89]

Cross-sectional studies have shown that plasma and tissue glutathione concentrations decrease by approximately 10-15% per decade after age 45, and this decline is accelerated in conditions associated with chronic oxidative stress, including type 2 diabetes, cardiovascular disease, neurodegenerative diseases, HIV/AIDS, chronic liver disease, and chronic obstructive pulmonary disease (COPD) [2][3][10][11]
The samples were collected, drop-cast onto Formvar-coated copper grids, dried, and then visualized at predetermined time points (0, 1, 3, 7, 10, and 14 d)
