  • hydroxyl
  • one of the many ways by which ascorbic acid hampers bacterial growth is by the production of hydrogen peroxide, which further converts into hydroxyl free radicals. (mdpi.com)
  • Certain amino acids can counteract the inhibitory effect of hydroxyl free radicals by checking their oxidizing effect. (mdpi.com)
  • In addition, hydroxyl radicals can reduce disulfide bonds in proteins, specifically fibrinogen, resulting in their unfolding and scrambled refolding into abnormal spatial configurations. (hindawi.com)
  • It is described in this paper that hydroxyl radicals can be generated by ferric ions without any oxidizing agent. (hindawi.com)
  • However, beneficial effects of the great number of phytochemicals that are endowed with hydroxyl radical scavenging and/or iron chelating activities should not be considered as a proof for oxidative stress. (hindawi.com)
  • collagen
  • The lack of vital skin nutrients, as well as free-radical attack, can destroy collagen, the glue-like protein substance that along with specific skin protein firming strands called elastin, allow your skin to remain healthy, supple and have a youthful appearance. (antiagingresearch.com)
  • Diet
  • By contrast, a diet rich in fruits and vegetables and whole grains protects cardiovascular system and lowers blood pressure by reducing free radical stress [ 10 ]. (hindawi.com)
  • cell
  • When a free radical attacks, it can get into the cell and cause the mitochondrion, the powerhouse of the cell, to die or cease to function fully. (mydailymoment.com)
  • properties
  • Subsequently, investigation into the chemical and physical properties of C 60 (and larger fullerenes) has yielded an extensive amount of information about C 60 , including its avid reactivity with free radicals ( 1 ). (pnas.org)
