1. * Biological Absorption
Table 1 :The Antioxidative capacity of an “Antioxidant” is determined by its:
* Biological Absorption
* Concentration
* Rate constants for radical reactions
* Location – Aqueous or lipid domains (or in both phases)
* Mobility in hydrophobic domains
* Lifetime
* Rate of regeneration or recycling activity
* Metal scavenging (chelating, binding) activity

2. Table 2:Antioxidant Characteristics
1. Compounds called “Antioxidants” differ in their ability to react with different reactive oxygen / nitrogen species (ROS/RNS).
2. Combination of “Antioxidants” can provide a wider range of free radicals scavenging than an individual antioxidant.
3. Antioxidant treatment may be beneficial only in subjects under oxidative stress.
4. Some “Antioxidants” exhibit additional anti-atherogenic activities, beyond their antioxidant effect.
