superoksidi

Superoksidi refers to the molecule with the chemical formula O2-. It is an anion, meaning it carries a negative electrical charge, and is derived from molecular oxygen (O2). In superoksidi, one of the oxygen atoms has gained an extra electron, resulting in an unpaired electron. This makes superoksidi a free radical, a highly reactive species that can readily participate in chemical reactions.

Superoksidi plays a significant role in various biological and chemical processes. In biological systems, it is produced by certain enzymes, such as NADPH oxidase, as part of the immune response. These reactive oxygen species can help to destroy invading microorganisms. However, excessive production of superoksidi can lead to oxidative stress, which is implicated in aging and various diseases. Superoksidi can also be involved in industrial chemical reactions and environmental processes. Its reactivity allows it to initiate or propagate chain reactions. Due to its instability, superoksidi often reacts quickly with other molecules or undergoes dismutation, where two superoksidi molecules react to form oxygen and hydrogen peroxide.
