Free radicals in chemistry, biology and medicine: contribution of radiation chemistry
Free radical chemistry is one of the topics to which radiation chemistry has made many important and essential contributions. Research on these usually shortlived transients has been particularly enhanced since the development of time-resolved techniques such as pulse radiolysis (in radiation chemistry) [34, 64] and laser flash photolysis (in photochemistry) [11], which allowed direct observati...

Running title: Metabolism of cyclic nitrone superoxide adducts Manuscript Click here to view linked References 2 Abstract Reactive oxygen species (ROS) are by-products of aerobic metabolism involved in the onset and evolution of various pathological conditions. Among them, superoxide radical is of special interest as the origin of several damaging species such as H 2 O 2 , hydroxyl radical, or ...
متن کاملOxygen in Biology and Biochemistry: Role of Free Radicals
A free radical is defined as any atom or molecule that contains unpaired electrons and has independent existence (hence, the term free). A dot is used to represent a free radical species. The abstraction or gain of one electron by a nonradical molecule may (or may not) convert it to a radical species. Free radicals can have positive, negative, or neutral charges [reactions (12.1.1) and (12.1.2)].

Many genetic or environmental manipulations that extend life span in the nematode Caenorhabditis elegans (C. elegans) also enhance survival following acute stresses such as oxidative damage and thermal stress. This coupling of stress response and aging mechanisms has proved a useful tool in identifying new genes that affect the aging process without the need for performing lengthy life span ana...

Nicotinamide adenine dinuclotide phosphate reduced form (NADPH), an electron carrier, is a kind of antioxidants against the oxidative stress in the mitochondria. The major resources of NADPH are the pentose phosphate pathway and photosynthesis. This paper will focus on the structure, formation, reaction, detection and stability of NADPH. Jingru Liu NADPH 3 Introduction: Recently, reactive oxyge...
