It is clear that the loss of biological activity of human serum albumin by MCO system appears of medical relevance and if LA exerts similar effects seen in the present study, it is possible that cellular prooxidant activity can also result consuming this unique antioxidant in certain doses.
The Universal Soldier: Enzymatic and Non-Enzymatic Antioxidant Functions of Serum Albumin
It has been concluded that it is fundamentally possible to regulate the antioxidant properties of albumin with various ligands, and the binding and/or enzymatic features of the protein by changing its redox status.

It is proposed that, considering the poor glucose control found in diabetics as well as the key role of oxidative stress in vascular complications, glycation‐mediated and free radical‐induced impairment of the antioxidant properties of albumin might be important parameters in vascular complication encountered in diabetes.
Physiological and pathological changes in the redox state of human serum albumin critically influence its binding properties

This review examines the specific role of sulfur-containing amino acids in protein degradation and their possible interplay with the reversal of limited oxidative lesions, and the participation of proteins in the overall antioxidant defense is discussed, specifically the role of metallothionein as an intracellular antioxidant and that of albumin as a circulating antioxidant.
Contribution of superoxide to reduced antioxidant activity of glycoxidative serum albumin
