WebHCN ion channels are known contributors to bladder control, but their mechanism of action is not well understood. The lack of a definitive identification of cell type(s) expressing … HCN is formed in interstellar clouds through one of two major pathways: via a neutral-neutral reaction (CH 2 + N → HCN + H) and via dissociative recombination (HCNH + + e − → HCN + H). The dissociative recombination pathway is dominant by 30%; however, the HCNH + must be in its linear form.
