Cyclic adp ribose, frequently abbreviated as cadpr, is a cyclic adenine nucleotide like camp with two phosphate groups present on 5 oh of the adenosine like adp, further connected to another ribose at the 5 position, which, in turn, closes the cycle by glycosidic bonding to the nitrogen 1 n 1 of the same adenine base whose position n 9 has the glycosidic bond to the other ribose.
