• toxic
  • Vitamin C greatly enhances the ability of vitamin E to prevent damage to LDL, the so-called bad cholesterol, which, if damaged, is suspected of being the first step in the progression to heart disease, according to researchers at the University of California at Berkeley.In the past few years, scientists have found that oxygen-free radicals, toxic byproducts of normal chemistry, can damage LDL.

  • This nice little power-generating enterprise, however, produces highly toxic by-products: free radicals. (smartskincare.com)
  • vinyl
  • When a growing polymer chain reacts with the addition fragmentation agent the radical end-group attacks the vinyl bond and forms a bond. (wikipedia.org)
  • common
  • An iniferter is a chemical compound that simultaneously acts as initiator, transfer agent, and terminator (hence the name ini-fer-ter) in controlled free radical iniferter polymerizations, the most common is the dithiocarbamate type. (wikipedia.org)
  • effectively
  • The equilibrium is designed to heavily favor the dormant state, which effectively reduces the radical concentration to a sufficiently low level to limit bimolecular coupling. (wikipedia.org)
  • So one might ask, how effectively would say a vitamin E capsule or a glass of some exotic juice perform when confronted by this onslaught of free radicals? (huffingtonpost.com)
  • rate
  • The two options of SFRP are nitroxide mediated polymerization (NMP) and verdazyl mediated polymerization (VMP), SFRP was discovered while using a radical scavenger called TEMPO when investigating the rate of initiation during free radical polymerization. (wikipedia.org)
  • important
  • Some important aspects of these are compared in the table: Although not a strictly living form of polymerization catalytic chain transfer polymerization must be mentioned as it figures significantly in the development of later forms of living free radical polymerization. (wikipedia.org)
  • Skin
  • Collagen and elastin are the major elements that maintain firmness of the skin which are destroyed by free radicals, giving rise to deep wrinkles. (hubpages.com)
  • atom
  • Similar to atom transfer radical polymerization (discussed below), the equilibrium between dormant chains (those reversibly terminated with the stable free radical) and active chains (those with a radical capable of adding to monomer) is designed to heavily favor the dormant state. (wikipedia.org)
  • From all LRP methods, Atom transfer radical polymerization or ATRP is the most studied and since its development in 1995 an exhaustive amount of articles has been published about this topic. (wikipedia.org)
  • process
  • Thus, the redox process gives rise to an equilibrium between dormant (Polymer-Halide) and active (Polymer-radical) chains. (wikipedia.org)
