Experimental data are presented which were obtained under comparative evaluation of influen­ce of different freezing-thawing conditions on antioxidant properties of isolated proteins: human serum albumin, cytochrome с from the horse heart and glucose oxidase from Aspergillus niger. The observed protein antioxidant activity alterations are assumed to be a result of protein conformational changes. The character of freezing-thawing influen­ce on the protein antioxidant activity depends on the molecular structure and cooling conditions.

Key words: albumin, glucoseoxidase, cytochrome с, freezing-thawing, antioxidant activity.
