The copper peptide is a powerful anti-ageing ingredient

Such a relationship is not surprising because most diurnal or nocturnal organisms display daily oscillations in energy intake, locomotor activity, and exposure to exogenous and internally generated oxidants ( The discovery and repeated confirmation of melatonin as an oxygen-based free radical scavenger and antioxidant represents a paradigm shift ( Not only is melatonin produced by peripheral cells, but importantly it is likely generated specifically in mitochondria ( Figure 3 ) ( Figure 3 Locally produced melatonin also protects the intramitochondrial environment from oxidative stress since in addition to acting as a direct radical scavenger it also stimulates enzymes, i.e., superoxide dismutase 2 (SOD2) and glutathione peroxidase (GPx), that remove ROS from the mitochondrial matrix ( The normal nocturnal rise in pineal melatonin and its release (Source # 1) are mediated due to the interaction of postganglionic neuron norepinephrine (NE) with specific receptors on the pinealocyte membrane ( In comparison to what is known about Source # 1 melatonin regulation, information about the control of extrapineal/mitochondrial melatonin (Source # 2) production is negligible
