Title: Adenosine Diphosphate
CAS Registry Number: 58-64-0
CAS Name: Adenosine 5¢-(trihydrogen diphosphate)
Additional Names: ADP; adenosine 5¢-pyrophosphoric acid; 5¢-adenylphosphoric acid; adenosinediphosphoric acid
Molecular Formula: C10H15N5O10P2
Molecular Weight: 427.20
Percent Composition: C 28.11%, H 3.54%, N 16.39%, O 37.45%, P 14.50%
Literature References: Formed from ATP in the muscle by the enzyme adenosinetriphosphatase upon stimulation of the muscle unless hydrolysis is prevented by injection of magnesium sulfate. Prepd by hydrolysis of ATP: LePage, Biochem. Prep. I, 1 (1949). Synthesis: Chambers et al., J. Am. Chem. Soc. 82, 970 (1960). See also the ref and data under Adenosine Triphosphate.
Derivative Type: Barium salt
Molecular Formula: Ba3(C10H12N5O10P2)2
Molecular Weight: 1260.34
Percent Composition: Ba 32.69%, C 19.06%, H 1.92%, N 11.11%, O 25.39%, P 9.83%
Properties: The purity of the prepns can be checked by analyses for nitrogen, ribose (orcinol reaction), total phosphorus, easily hydrolyzable phosphorus, and inorganic phosphorus. ADP should give a ratio of 2:1 for total organic phosphorus to easily hydrolyzable phosphorus. uv max (pH 7.0): 259 nm (aM 15.4 ´ 103).
Absorption maximum: uv max (pH 7.0): 259 nm (aM 15.4 ´ 103)
