Abstract
U živim organizmima, pa tako i kod čovjeka, slobodni radikali su proizvodi normalne respiracije i staničnih procesa. Antioksidansi su tvari koje sprječavaju reakcije oksidacije/autooksidacije kojima mogu nastati slobodni radikali. Najvažniji prirodni antioksidansi su vitamin C, tokoferoli (vitamin E) i vitamin A. Vitamin C je jedini u vodi topljivi vitamin koji djeluje kao elektron donor i esencijalni nutrijent te je ključan u regeneraciji vitamina E. Vitamin E i vitamin A su u mastima topljivi vitamini. Vitamin E nalazi se u membrani stanice i štiti je od oksidacije. Vitamin A nastaje od pro-vitamina A (najviše β-karotena). I vitamin E i vitamin A ključni su u zaštiti od peroksilnih radikala.Suplementacija prehrane vitaminima pokazala se u brojnim slučajevima neučinkovita, pa čak i štetna. Puno bolje rješenje je održavanje zdravih navika, raznovrsne prehrane i tjelovježbe što će pomoći u održavanju zdravlja i čime možemo zadovoljiti sve potrebe organizma, pa tako i toliko nam važne vitamine s antioksidativnim djelovanjem.
Abstract (english)
In living organisms, including humans, free radicals are products of normal respiration and cellular processes. Antioxidants are substances that can prevent oxidation/autooxidation reactions that can produce free radicals. The most important natural antioxidants are vitamin C, tocopherols (vitamin E) and vitamin A. Vitamin C is the only water-soluble vitamin that acts as an electron donor and essential nutrient and is crucial in the regeneration of vitamin E. Vitamin E and vitamin A are fat-soluble vitamins. Vitamin E is found in the cell membrane and protects it from oxidation. Vitamin A is formed from pro-vitamin A (mostly β-carotene). Both vitamin E and vitamin A are crucial in protecting against peroxy radicals. Dietery supplementation with vitamins has been shown to be ineffective and even harmful in numerous cases. A much better solution is to mantain healthy habits, a varied diet and exercise, which will help mantain health and with which we can meet all the needs of the body, including vitamins with antioxidant activity, which are so important for us.
