Superoxide anion as a cofactor of dopamine-β-hydroxylase

Biochemical and Biophysical Research Communications, 1978
Abstract Superoxide anion can serve a reducing agent for tyramine hydroxylation by dopamine-β-hydroxylase. Stable O 2 • solutions were obtained by dissolving KO2 in dry dimethylsulfoxide and infused into buffered solutions of tyramine and dopamine-β-hydroxylase at constant rate.

Predicting solvent stability in aprotic electrolyte Li-air batteries: nucleophilic substitution by the superoxide anion radical (O2(•-)).

Journal of Physical Chemistry A, 2011
There is increasing evidence that cyclic and linear carbonates, commonly used solvents in Li ion battery electrolytes, are unstable in the presence of superoxide and thus are not suitable for use in rechargeable Li-air batteries employing aprotic ...

Progress on Electrochemical Determination of Superoxide Anion

Chinese Journal of Analytical Chemistry, 2014
Abstract Superoxide anion (O2·−) is the primary species of the reactive oxygen species (ROS), resulting from the metabolism of O2 in the living organisms. Its dynamic changes can provide broad implications in physiological and pathological conditions.

The Generation of Superoxide Anion by Various Types of Phagocyte

Journal of Infectious Diseases, 1975
Polymorphonuclear leukocytes derived from human peripheral blood, rabbit peritoneal exudates, and guinea pig peritoneal exudates generate measurable quantities of superoxide anion when challenged with opsonized zymosan, but not when challenged with zymosan that has not been opsonized.

High density lipoprotein is a scavenger of superoxide anions

Biochemical Pharmacology, 1990
Present work describes a new property of HDL to act as a scavenger of O2- free radicals in vitro. This lipoprotein prevents both enzymic and non-enzymic generation of O2- anions as evidenced by inhibition of xanthine oxidase, peroxidase, peroxidation of pyrogallol and phenazine methosulphate-NADH reaction.
