The oxygen(-2) anion, also known as the superoxide anion, is a negatively charged molecule composed of one oxygen atom and an extra electron. It is a highly reactive species that plays a vital role in various biological processes, including cellular respiration and immune response. The superoxide anion is generated as a byproduct of normal metabolic activities within the body, and its excessive accumulation can result in oxidative stress and cellular damage. Additionally, it serves as a precursor for the formation of other reactive oxygen species, such as hydrogen peroxide and hydroxyl radicals. Superoxide dismutase, an enzyme that catalyzes the dismutation of superoxide into oxygen and hydrogen peroxide, is essential for regulating the levels of this significant yet potentially harmful molecule.

Uses
Used in Biological Processes:The oxygen(-2) anion is used as a crucial component in cellular respiration and immune response for its role in facilitating metabolic activities and defending against pathogens.
Used in Oxidative Stress and Cell Damage:
The oxygen(-2) anion is used as a biomarker for oxidative stress and cell damage, as its accumulation can indicate an imbalance in the body's antioxidant defense mechanisms.
Used in Reactive Oxygen Species Formation:
The oxygen(-2) anion is used as a precursor in the formation of other reactive oxygen species, such as hydrogen peroxide and hydroxyl radicals, which are involved in various physiological and pathological processes.
Used in Enzymatic Regulation:
The oxygen(-2) anion is used as a substrate for the enzyme superoxide dismutase, which helps regulate its levels and prevent potential harm to the body by catalyzing its dismutation into oxygen and hydrogen peroxide.
Check Digit Verification of cas no
The CAS Registry Mumber 469906-25-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,6,9,9,0 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.Calculate Digit Verification of CAS Registry Number 469906-25:
(8*4)+(7*6)+(6*9)+(5*9)+(4*0)+(3*6)+(2*2)+(1*5)=200
200 % 10 = 0
So 469906-25-0 is a valid CAS Registry Number.
