... • Specific activity depends on half-life, and is totally independent of mode or energy of decay. • When decay occurs for all of the biologically important isotopes (14C; 3H; 32P; 35S; 125I; etc.), the decay event changes the chemical identity of the decaying atom, and in the process, destroys the mo ...

Nicotinic agonist
A nicotinic agonist is a drug that mimics the action of acetylcholine (ACh) at nicotinic acetylcholine receptors (nAChRs). The nAChR is named for its affinity for nicotine.Examples include nicotine (by definition), acetylcholine (the endogenous agonist of nAChRs), choline, epibatidine, lobeline, varenicline and cytisine.
