| Radical Chemistry and Type 1 diabetes What is Free Radicals? In cellular metabolism, lipid peroxidation is a well-defined   mechanism   of cellular damage in both animals and plants as fatty acids   undergo a   chemical reaction with oxygen to produce energy. In other   words Reactive Nitrogen Species(RNS) and Reactive Oxygen Species(ROS) such as: superoxide, hydroxyl radical, hydrogen peroxide and other free radicals, which are all natural by-product of normal cell metabolism of oxygen,     and enzymatic activity of inducible nitric oxide often compromise the     integrity of the cell membrane.
  Radicals   (often referred to as free radicals) is an atom or a group of   atoms   with at least one unpaired electron. The unpaired electrons cause     radicals to be highly chemically reactive. In the body it is usually an     oxygen molecule that has lost an electron, and the only way to   stabilize   itself is to steal an electron from a nearby molecule.
 ROS and RNS radicals have important roles in cell   signalling and   homoeostasis that offset disrupting changes in the   body. However, if one   does not take in adequate nutrition such as   antioxidants, free radical   levels can increase dramatically and become   cytotoxic (toxic to cells)   and alter normal cell activity, especial   during times of stress. The   overwhelming and continuous onslaught from   free radicals is what destroy   the beta cells that produces the   hormone insulin in the   isles of Langerhans in the pancreas.  |
