Notably, GSH binding motif is not conserved among the other seleno-GPxs (GPx2, GPx3, GPx4, and GPx6) justifying their abilities to use wide variety of thiols like cysteine, protein thiols, mercaptoethanol, and dithiothreitol in addition to GSH as reducing equivalent for the catalysis [8, 17, 18]

ALDH is a marker for both normal stem cells and CSCs and is an intracellular enzyme that converts retinol into retinoic acid, and detoxifies the cellular system [59]
Interestingly, Epithalons ability to increase NAD levels (nicotinamide adenine dinucleotide) could also play a role in boosting energy production, enhancing performance, and reducing fatigue
