glutathione is amino acid precursors to Synthase 13: Metabolism of Methionine &

GSH can also be oxidized to its disulfide form (GSSG) by reactive oxygen species (ROS) and other electrophiles, which can be reduced back to GSH by GR using NADPH as a reducing agent

The role of copper in this regard is argued to be protective, with copper being released into the synaptic cleft at concentrations of up to 100 M upon depolarization, inhibiting the activity of postsynaptic NMDA, AMPA, and GABA receptors upon binding, thus preventing overstimulation in a negative feedback system (DAmbrosi and Rossi, 2015)

Cats are common carriers of pollen and dust particles, which can exacerbate allergies

Sure, some of the concepts are complex, but you can find some super interesting and helpful information out there
