D-ribose is a naturally occurring five-carbon sugar found in all living cells, as well as in RNA-containing viruses. It is not an essential nutrient, since it can be made in the body from other substances, such as glucose. D-ribose, however, is very essential for life. It is the material used in the synthesis of vitamin B2, Tetra-o-Acetyl - Ribose and nucleoside etc, also used as health product in sports or used for food additives.
