Vitamins as Antioxidants

CSEF · 2013 Plant Biology

Lisa A. Yanuaria · Bravo (Francisco) Medical Magnet High School, Los Angeles, Los Angeles County

Overview

Objectives/Goals The goal of this experiment is to determine which vitamin (A, C, or E) has the strongest antioxidant activity. Methods/Materials Solutions of each vitamin (A, C, E) were mixed with 1.5% hydrogen peroxide solution in a 5:1 ratio and applied to 20 radish seeds in a total of 14 trials (a total of 840 radish seeds). A negative control using 20 radish seeds grown in 3% hydrogen peroxide and a positive control containing 20 seeds grown in distilled water were used. Results The results indicated that vitamin A as retinyl palmitate had the strongest antioxidant activity. Conclusions/Discussion My hypothesis that vitamin A as ascorbic acid would be the strongest antioxidant was not supported by my results.

Summary statement

My project is about which vitamin (A, C, or E) is the strongest antioxidant.

Help received
