Antioxidant activity via Vitamin E tocopherols

Molecular classification: Other (Antioxidant)

Overview

Vitamin E tocopherols, particularly alpha-tocopherol, function as fat-soluble antioxidants that protect cell membranes from oxidative damage by scavenging free radicals and inhibiting lipid peroxidation. This activity is crucial for maintaining cellular integrity and preventing oxidative stress-related diseases. Vitamin E also plays roles in immune function, cell signaling, and gene expression regulation.

Other names: Vitamin E antioxidant activityTocopherol antioxidant activity

Mechanism of action

Scavenging free radicals; Inhibiting lipid peroxidation; Modulating enzyme activities (e.g., protein kinase C)
