What is the Origin of Free Radical Scavenging Efficacy?

The term is rooted in biochemistry and the study of oxidative stress, where "free radicals" are highly reactive molecules lacking a full electron pair. "Scavenging" describes the chemical neutralization process, and "Efficacy" quantifies the success of this protective mechanism. Its relevance in hormonal health stems from ROS's role in disrupting endocrine receptor function.

What is the Mechanism of Free Radical Scavenging Efficacy?

Antioxidants function by donating an electron to stabilize the free radical without becoming reactive themselves, effectively terminating the chain reaction of oxidative damage. For instance, certain vitamins or polyphenols directly quench superoxide or hydroxyl radicals in lipid membranes or the cytoplasm. Upregulating this efficacy supports mitochondrial health and preserves the structural integrity of sensitive biomolecules like steroid precursors.

Free Radical Scavenging Efficacy

Meaning

Free Radical Scavenging Efficacy measures the quantitative capacity of endogenous or exogenous antioxidant systems to neutralize reactive oxygen species (ROS) before they induce cellular damage, particularly lipid peroxidation and DNA adducts. High efficacy indicates robust protection against oxidative stress, a key driver of cellular aging and inflammation. This metric is central to assessing redox homeostasis.
