| guanosine tetraphosphate | <chemical> Guanosine 5'-diphosphate 2'(3')-diphosphate. A guanine nucleotide containing four phosphate groups. Two phosphate groups are esterified to the sugar moiety in the 5' position and the other two in the 2' or 3' position. This nucleotide serves as a messenger to turn off the synthesis of ribosomal RNA when amino acids are not available for protein synthesis. Synonym: magic spot I. Chemical name: Guanosine 5'-(trihydrogen diphosphate), mono(trihydrogen diphosphate) (ester) (12 Dec 1998) |

| diadenosine 5,5'''-P(1),P(4)-tetraphosphate alpha,beta-phosphorylase | <enzyme> Ap4a + inorganic po4 forms ATP + ADP Registry number: EC 2.7.7.53 Synonym: ap4a phosphorylase, ATP adenylyltransferase (26 Jun 1999) |
| adenosine | <biochemistry> A ribonucleotide which consists of the nitrogenous base adenine linked to the sugar ribose. <drug> A cardiac drug used in terminating PSVT involving reentry pathways that include the AV node or Wolff-Parkinson-White syndrome. For atrial flutter, atrial fibrillation, atrial or ventricular tachycardias, adenosine may produce transient AV block that may help identify the rhythm. Pharmacologic action: Endogenous purine nucleoside that depresses AV node and sinus node activity. Brief duration of action (1-2 min). Dose: Rapid 6 mg IV bolus over 1-3 sec. May repeat at 12 mg IV bolus within 1-2 min Patients taking theophylline may require larger doses. Use a smaller dose with cardiac transplant patients. Potential complications: Common but transient - flushing, dyspnea, chest pain, bradycardia, and ventricular ectopy. Theophylline (and caffeine) blocks adenosine's effects. Dipyridamole potentiates adenosine's effects. Use other agents to avoid these drug interactions. (15 Mar 2000) |
| adenosine 3',5'-cyclic monophosphate | An activator of phosphorylase kinase and an effector of other enzymes, formed in muscle from ATP by adenylate cyclase and broken down to 5'-AMP by a phosphodiesterase; sometimes referred to as the "second messenger."

| adenosine 3',5'-cyclic phosphate phosphodiesterase | <enzyme> An enzyme that catalyses the hydrolysis of adenosine 3',5'-cyclic phosphate forming 5'-AMP.

| adenosine 3'-phosphate 5'-phosphosulfate | 3'-phosphoadenosine 5'-phosphosulfate;an intermediate in the formation of urinary ethereal sulfates, notable for containing a "high energy" sulfate bond; the 3'-OH of adenosine is replaced by -OPO3H2, the 5'-OH by -OP(O2H)-OSO3H. Synonym: active sulfate. Acronym: PAPS (05 Mar 2000) |
