When ROS levels exceed those of antioxidant defenses, there is an aberrant increase in free radical generation resulting in mitochondrial damage and leading to oxidative stress and subsequently this increased stress can reduce ETC activity (Gu et al., 2013) (Figure 2)
Handling and Stability Risks Improper handling exposure to light, heat, repeated freeze-thaw cycles, or strongly alkaline conditions can degrade the peptide or disrupt copper coordination, producing experimental variability that is sometimes mistaken for biological inconsistency
The following recommendations are derived from the comparative data
