Words similar to antioxidant
Example sentences for: antioxidant
How can you use “antioxidant” in a sentence? Here are some example sentences to help you improve your vocabulary:
Vitamin E is an essential nutrient, the main lipid soluble antioxidant, and plays a significant role in protecting biological membranes and lipoproteins from damage caused by free radicals generated during lipid peroxidation [ 1 2 3 ] . Recent information suggests that vitamin E also has functions unrelated to its role as an antioxidant [ 4 ] . Vitamin E is often equated only with alpha-tocopherol since this form is the most potent in protecting the fetuses of pregnant female rats from death and resorption.
Impaired pulmonary function is a strong predictor of cardiovascular and all-cause mortality in the general population independent of smoking [ 1 2 3 4 ] . The factors that influence pulmonary function are not completely understood and oxidant exposure could play a negative role [ 5 6 7 ] . Support for this hypothesis comes from studies that report a positive association between antioxidant vitamin status and lung function [ 8 9 10 11 ] . Several studies have indicated that alcohol exposure may contribute to oxidative burden and, therefore, it may be linked to impaired pulmonary function through oxidant-antioxidant mechanisms [ 12 13 14 15 ] . However, while alcohol itself can act as an oxidant, wine has antioxidant properties [ 12 13 16 17 ] .
Evidence for cardiotoxicity, as observed in this study, was not expected as supplementation with vitamin E at extremely high doses gave no significant indications of harmful side-effects in animals or in humans [ 18 25 ] . Perhaps vitamin E supplementation acts to inhibit lipid peroxidation but at the same time acts to down regulate other protective antioxidant systems as suggested by the antioxidant enzyme gene expression data in Table 4. If gene expression levels in Table 4reflect antioxidant enzyme activity, then an increase in SOD and decrease in GPX without an increase in CAT would result in accumulation of inorganic and organic peroxides and hydroperoxides that can react with Fe 2+to yield highly reactive free radical products that can damage cellular proteins and DNA as well as lipids.
A complete set of data was taken on each heart, which allowed calculation of the ratio of each antioxidant gene transcript to each of the other gene transcripts.
Nutritional status indicators showed that wine drinkers had the highest levels of serum antioxidant vitamins.
