Oxidative stress is a term that was introduced by Sies in and refers to any situation where there is a serious imbalance between the production of FR or reactive oxygen species (ROS), called the oxidative load, and the antioxidant defense by:

      Vitamin E is considered a major antioxidant in biomembranes, but little evidence exists for this function in plants under photooxidative stress. Leaf discs of two vitamin E mutants, a tocopherol cyclase mutant (vte1) and a homogentisate phytyl transferase mutant (vte2), were exposed to high light stress at low temperature, which resulted in bleaching and lipid Cited by: Biological Function: Cholesterol Oxidation Protection in LDL. Vitamin E is a true antioxidant and a very powerful and essential nutrient.. Vitamin E is a major lipid soluble antioxidant in Biomembranes and one of the ‘vitamins of choice’ by the liver that includes it when packaging a Low density Lipoprotein (LDL) for cholesterol transport.. The LDL is miniscule in size .

The term “antioxidant” is not always clearly defined in either popular or scientific literature. In the most general sense, a natural or synthetic antioxidant directly or indirectly functions to minimize damage to biomolecules (mostly proteins, lipids, and DNA) caused by reactive oxygen species (ROS) and/or reactive nitrogen oxide species (RNOS).

Size matters to antioxidant activity. The size of the phenolic head of tocopherol and tocotrienol decreases in the order: alpha > gamma = beta > delta, containing 3, 2 and 1 methyl group(s).

Recently, a new assay method for the quantification of the singlet oxygen absorption capacity (SOAC) of antioxidants (AOs) and food extracts in homogeneous organic solvents was proposed. In this study, second-order rate constants (kQ) for the reaction of singlet oxygen (1O2) with eight different carotenoids (Cars) and α-tocopherol (α-Toc) were measured in an aqueous Triton X Cited by: 5.

The lipid-soluble antioxidants α-tocopherol and carnosic acid were studied in field-grown rosemary (Rosmarinus officinalis L.) plants subjected to drought. During summer in the Mediterranean region, the predawn water potential decreased to −3 MPa and the relative water content to 42%, which caused a depletion of the maximum diurnal CO2 assimilation rate by 80%.

Tocopherol belongs to the Vitamin E class of lipid soluble antioxidants that are essential for human nutrition. In plants, tocopherol is synthesized in plastids where it protects membranes from oxidative degradation by reactive oxygen species.
