Significance of Antioxidant defense
Antioxidant defense refers to the body's biological mechanisms that protect against oxidative damage caused by free radicals and reactive oxygen species. These defenses comprise various enzymatic and non-enzymatic systems, including substances like ascorbic acid and luteolin, that help mitigate cellular damage from oxidative stress. When these mechanisms are overwhelmed, it can lead to an imbalance, resulting in oxidative stress, which can have detrimental health effects. Thus, effective antioxidant defense is crucial for maintaining cellular health and preventing damage.

The concept of Antioxidant defense in scientific sources
Antioxidant defense is a biological mechanism that protects cells from oxidative damage through enzymatic and non-enzymatic systems, including substances like ascorbic acid, mitigating harmful effects from free radicals and oxidative stress.

(1) These are the body's natural mechanisms which can be overwhelmed by oxygen free radicals, which leads to a state of oxidative stress within the body.[1] (2) These are the mechanisms in place to protect against damage from free radicals, and an imbalance can lead to oxidative stress.[2] (3) This refers to the body's mechanisms to protect against damage, and the protective role of luteolin on this defense system is studied in an experimental model.[3] (4) This refers to the body's mechanisms for protecting itself against damage from free radicals, which stingless bee honey boosted.[4] (5) This refers to the body's natural system to protect cells from damage caused by reactive oxygen species, including enzymes and other molecules.[5]
