Adenosine triphosphate | Cyclic adenosine monophosphate | adenosine triphosphate | Adenosine diphosphate | Adenosine A1 receptor |
This structure is defined, in part, as the place where adenosine acts on A1 receptors of cholinergic neurons.
Fraction S2 contains two phospholipases A2 — PLA2 I and PLA2 II; fraction S3 contains four cytotoxin homologues — maticotoxins A, C, D1 and D2; and fractions S4 and S5 contain a large amount (about 1 mg/specimen) of adenosine with smaller amounts of inosine and guanosine.
It is a derivative of the nucleoside adenosine, differing from the latter by the replacement of a hydroxyl group (-OH) by hydrogen (-H) at the 2' position of its ribose sugar moiety.

N6-Cyclopentyladenosine (CPA) is a drug which acts as a selective adenosine receptor agonist.
The protein encoded by this gene is a member of the AAA family of adenosine triphosphatases (ATPases), is related to the Clp protease/heat shock family and is expressed prominently in the substantia nigra pars compacta.
Complementary binding between U2 snRNA (in an area lying towards the 5' end but 3' to hairpin I) and the branchpoint sequence (BPS) of the intron results in the bulging out of an unpaired adenosine, on the BPS, which initiates a nucleophilic attack at the intronic 5' splice site, thus starting the first of two transesterification reactions that mediate splicing.
Uridine is one of the four basic components of ribonucleic acid (RNA); the other three are adenosine, guanosine, and cytidine.
