RESUMO
1. Oxalic acid protects adrenalin against oxidation, in the presence of copper, as well as other substances of biological interest, such as ascorbic acid, p-aminobenzoic acid and tyrosin. 2. The mechanism ol action can be a combination of oxalic acid with copper and iron ions in the oxidative system, forming very little ionizable copper and iron oxalate. 3. Oxalic acid should not be considered as an undesirable catabolic product, but on the contrary, as an agent with active participation in the phenomenon of intra-organic oxido-reduction.
