Antioxidant Enzymes: Three or Four Veggies a Day Keeps Aging Away

Rating
0.0 stars

The purpose of this video lesson is to expand the student's knowledge about enzymes by introducing the antioxidant enzymes that are intimately involved in the prevention of cellular damage and eventual slowing of the aging process and prevention of several diseases. Students will learn that natural antioxidant enzymes are manufactured in the body and provide an important defense against free radicals. The topic of free radical action is introduced, covering how they are constantly generated in living cells both by ''accidents of chemistry'' and also by specific metabolic processes.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Sponges are a diverse group of aquatic animals with porous bodies that produce a vast array of natural products, some with important medicinal properties, but their porous body structure also provides ample habitat for symbiotic microorganisms, which can account for up to 35% of their total body weight. Previous studies looking at the unique natural products produced by sponges have rarely taken this close relationship into account, making the extent to which microorganisms actually produce them unclear. To fill this gap, a team of researchers identified the chemical compounds found in the tissues of six sponge species from the Great Barrier Reef and their symbiotic microbes. Several compounds with potential roles in competition and defense against intruding organisms and oxidative stress were specifically attributed to the microbial cells, while the compounds produced by the sponge tissues may provide nutrients to the symbiotic microorganisms and aid in sponge defense..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.
