CAT and malaria: The main sources of antioxidant defenses involved in malaria are: (1) host enzyme antioxidants (SOD, CAT, GSH-Px, GST, GR, Prx, and Trx); (2) host non-enzymatic antioxidants (vitamins A, D, E, and C; carotenoids; uric acid; and GSH); (3) non-enzymatic antioxidants from the host’s metal chelation system (iron, copper, and metallothionein-chelating proteins); (4) exogenous antioxidants of dietary origin or drugs (flavonoids, phenolic compounds, minerals, NAC, and the mushroom A. sylvaticus).
