Antioxidant News and Research

RSS

Antioxidants are substances that protect cells from the damage caused by free radicals (unstable molecules made by the process of oxidation during normal metabolism). Free radicals may play a part in cancer, heart disease, stroke, and other diseases of aging. Antioxidants include beta-carotene, lycopene, vitamins A, C, and E, and other natural and manufactured substances.

Study Unveils the Complete Biosynthetic Loop Regulating Tannin Production in Strawberries

Hydrolyzable tannins (HTs), including gallotannins and ellagitannins, are essential polyphenolic compounds that influence fruit taste, antioxidant capacity, and stress tolerance. Although condensed tannin biosynthesis has been well studied, the enzymatic processes governing HT formation remain unclear.
