Superoxide dismutase

Superoxide dismutase (CAS 9054-89-1 ), commonly abbreviated as SOD, is an enzyme that catalyzes the dismutation of superoxide radicals into oxygen and hydrogen peroxide.

In commercial applications, it functions as a biological antioxidant, neutralizing reactive oxygen species in formulations, biological systems, and food matrices where oxidative degradation is a primary quality concern.

In cosmetic and personal care formulations, SOD is incorporated into anti-aging creams and serums to protect skin cells from oxidative stress-driven degradation during daily exposure.

Food and nutraceutical manufacturers use it as a functional ingredient in dietary supplements targeting cellular antioxidant support. Pharmaceutical and biotech applications include its use as an active component.

It is utilized in topical drug products and as a research reagent for oxidative stress assays. In food processing, SOD is evaluated for extending shelf life in products where lipid oxidation limits stability.

Superoxide dismutase is supplied as a lyophilized powder or liquid concentrate, with activity expressed in units per milligram. Grades available include food-grade and cosmetic-grade material.

Research-grade preparations with defined specific activity are also available for laboratory use. Sourcing origin varies between bovine, human recombinant, and plant-derived sources like melon.

Each source carries different regulatory and labeling implications for buyers. These variations ensure that the enzyme meets specific industry requirements for purity and biological activity levels.
