Modifications of Superoxide dismutase, catalase and isofermentative forms under the influence of polyphenols extracted from dandelion (Taraxacum officinale)

Abstract

As a result of the vital activity of living organisms through the metabolism of energy substances, the formation and accumulation of reactive oxygen species (ROS) occurs, regardless of the state of bio-objects, that is, with the physiological or pathological course of these metabolic processes. At the same time, living organisms have formed antioxidant protection systems against these invasive and toxic substances. Given that these toxic substances influence negatively on endocellular, exocellular metabolic processes and in general the body`s tissues, they can cause various pathological conditions and disturbances in the stable functioning of the body. In this paper are analyzed some researches on the enzymatic activity of superoxide dismutase, isofermentative forms of this and catalase. Superoxide dismutases (SOD) possess the ability to convert superoxide into hydrogen peroxide, which is then removed by catalase. Analyzing the obtained results of these researches about the role of these enzymes from the first line of antioxidant protection we will obtain information that will demonstrate their activity under the influence of dandelion polyphenols.
