Our Subversive Free Radicals II

Mutations to your DNA caused by free radicals are a major cause of cancer. Free radicals can make blood clot abnormally in our arteries by destroying our body’s ability to make PGI, (prostacyclin), a natural anti-clot hormone found in healthy arteries. Free radicals are also implicated in arthritis. Most of the brain damage caused by […]

Cross-linked Molecules and Aging in Skin, Arteries, and Other Tissues III

Proteins are complex molecules, made up of amino acids, which perform a wide variety of functions in the human body, from chemical reaction-controlling enzymes, to structural molecules like collagen, to necessary components in human memory. In order to function properly, proteins must assume a correct three-dimensional configuration. In their proper shape, some proteins act as […]
