Opis:
Free radicals containing one or more unpaired electrons have considerable reactivity. Those radicals derived from oxygen represent the most important class of such species. Free radicals generated in organism are reactive oxygen species (ROS) and reactive nitrogen species (RNS) well recognised for playing a dual role as both deleterious and beneficial species. The cumulative production of ROS/RNS is termed oxidative stress and were discovered in pathomechanism of many of diseases. It was observed that in medium concentration ROS and RNS are play a role in inflammation, apoptosis and as secondary messengers in intracellular signalling cascades.

zinc functions
Opis:
Zinc is a metallic element, of symbol Zn and atomic number 30, that is placed in the group 12 of the periodic table. As an essential trace element, zinc is required to support human biochemical processes. It is found in nearly 200 specific enzymes in the living organisms, and it also serves as structural cofactor for many cellular proteins. [1] Zinc may exert pleiotropic effects in organism; for that, deficits of cellular zinc content can have catastrophic consequences and are linked to major pathophysiology, such as diabetes, stroke and malformations of brain function [2]. The complexity and importance of zinc homeostasis is reflected by the large variety and number of zinc-related proteins found in almost every cell compartment; for example, this biometal is transported through ZnT (Zn2+ transporter) family and ZIP family, proteins that are completely dedicated to zinc transport [2]. It is also noticeable, that between three and ten percent of all protein products of genes in mammalian genomes bind zinc, which is essential for their folding, activity or conformational change [2].

Opis:
It was reported that dietary fructose imposes a number of effects on lipid metabolism including hypertriglyceridemia. The daily intake of fructose in humans is mainly due to sucrose. It was reported that the consumption is still increasing, making a background for health implications. The mechanism of metabolic disorders is poorly understood, but a lot of studies indicate that the liver lipid homeostasis deregulation is essential for a fructose effect on metabolism. The aim of the study is to estimate if fructose affects the profile of fatty acids in in vitro and in vivo models. In this study in vitro and in vivo experiments were conducted to assess the effect of dietary fructose on the fatty acid profile in the cell culture or in the liver of rats. The results showed that in the fructose experimental groups, both in the cell and liver homogenates, the content of the saturated fatty acids were significantly higher than in control groups. According to the obtained data fructose in the medium and in the diet affects saturation of fatty acids in the cell cultures and in the livers of rats. The findings obtained in the experiments support the thesis that fructose influences the homeostasis of lipid metabolism in the liver and may give an opportunity to discuss the limitation of the content of this kind of sugar in food.

Opis:
Alterations in membrane lipid composition, particularly fatty acids content is known to result in functional and structural changes. Dietary lipids and physical activity or stress play an important role in this change. It was of interest to study the influence of swimming in different temperatures on the content of fatty acids in the phospholipids of the erythrocyte membranes of rats. Our research demonstrated a significant influence of swimming on the content of fatty acids in the phospholipids of the erythrocyte membranes of rats. These changes of fatty acids, particularly the decrease of arachidonic acid and significant increase of saturated fatty acids in the phospholipids of the erythrocyte membranes in swimming rats may be induced by oxygen radicals generated in different kinds of stress.
