antioxidants

In the context of the infl uence of negative environmental and social factors, prolonging human active life and curbing age-related changes have become an urgent task. One way to solve these problems is to eat foods rich in antioxidants, such as vitamin E, polyphenols, tannins, anthocyanins, carotenoids. Breeders work on expanding the resource potential of products with functional properties. One global trend is the development of wheat varieties rich in purple grain antioxidants.

The influence of syntetical compound with antioxidative activity on increaseing of vitality gram-positive and gram-negative microorgan­ isms under stressful action of antibiotical factors was shown.

The purpose of this study was the investigation of lipid peroxidation products and photosynthetic pigment content in cells of herbs of various species in conditions of anthropogenic pollution of Tyumen. The material for the research was collected near different plants of Tyumen: metallurgical, engine, oil refinery, battery manufacturing as well as highway pollution. The following species of plants were analysed: coltsfoot (Tussilago farfara), red clover (Trifolium rubens), chamomile (Matricaria chamomilla) and wild vetch (Vicia cracca).

Lipid peroxidation is a key factor in programmed cell death of various etiologies. This process also occurs when ionizing radiation acts on biological systems. It is the essence of the theory of lipid radiotoxins, which is part of the structural and metabolic theory of the biological action of ionizing radiation. Non-enzymatic lipid peroxidation eventually leads to death by the mechanism of ferroptosis, while enzymatic lipid peroxidation, catalyzed by the cytochrome c-cardiolipin complex, triggers apoptosis along the mitochondrial pathway.
