D-Ribose is a carbohydrate which can be found naturally in the body of every living organism including humans, and is necessary on the process of creating energy as it is one of the primary precursors to ATP (Adenosine Triphosphate) synthesis, and also helps to maintain normal levels of ATP in the body. ATP is the driving force behind just about all cellular processes going on in the body. It is a molecule which is responsible for storing energy created by certain reactions and then later dispersing it during intense exercise and regular everyday activities. It can be found in the nucleoplasm and cytoplasm of the cell structure and is necessary in virtually every single cellular process that requires energy to operate. When food in each cell goes through the oxidization process, the energy that results from this action is taken and turned into ATP so that there is always a surplus contained in each cell to fuel it.
