No close but chemically different they play different roles in your biochemistry. Deoxyribose is part of the DNA and RNA structure. So it helps repair them. D-ribose is an intermediary in the process of converting O2 gas into ATP used to store oxygen for later use. We burn ATP not O2. ATP is manufactured in every living cell by tiny reaction sites called mitochondria. The there I are thousands d off mitchondra in each cell. As I this number declines with age and the cellular has less energy and” less life function. This is a major factors in old age and death. Mitochondria can repair and build new ones with the right chemical supplements. We have reached an age where this is understood and all the ingredients are available. As an intermediary supplementing with D-Ribose decreases the work the mitochondria have to do so It increases ATP output from existing Mitochondria. In short D-D- Riboses iboosts you energy while you build more mitochondria to increase your energy naturaly. You cantact me if you want more information. I wrote a book that explains the rebuilding process for people who have antibiotic toxicity. A better place to start is Dale Bresenen,s “ End of Alzheimer’s” It is well written and gives thee information to restore brain health for much more that Alzheimer’s. My book is aaovailable as an Amazon Kindle “The Healthy Truth” by John Taylor. It contains my contact information and a questionnaires. Good,health to you

Not that I am aware of... I looked at their website and nothing is mentioned about corn... Though the first two ingredients say vegetable source that vegetable source is not corn.
