WebbKTM is a 16 amino acid peptide with the sequence WCCSYPGCYWSSSKWC. Here, we present the nuclear magnetic resonance (NMR) structure and bioactivity of this rationally designed α-conotoxin (α-CTx) that demonstrates potent inhibition of rat α3β2-nicotinic acetylcholine receptors (rα3β2-nAChRs). Two bioassays were used to test the efficacy … WebbNicotine (formula: C 10 H 14 N 2) is a parasympathomimetic alkaloid which binds to nicotinic acetylcholine receptors in the CNS. Its actions are complex as it is both a stimulant and a relaxant, and stimulates the presynaptic release of most major neurotransmitters in the brain. Read More: What is intestinal fortitude mean?
