Ach has a positive charge on the Nitrogen. This makes it harder for Ach to pass through lipophillic membranes which are nonpolar. Remember likes attract likes. Ach would prefer a polar environment like water.
quaternary amines or in slang - quats

Cationic detergents are the quaternary ammonium salt of acetates, chlorides or bromides. For example, alkyl trimethyl ammonium bromide
No, ligands are those which may donate pairs of electrons to a metal ion quaternary salts of nitrogen do not have free electrons pairs.
A benzalkonium is any of a class of quaternary ammonium cations containing a benzyl, two methyl and another, longer alkyl group.
Acetylcholine is also the principal neurotransmitter in all autonomic ganglia. In alternative fashion, acetylcholine can activate non-specific cation the body inappropriately produces antibodies against acetylcholine nicotinic a highly polar, charged ammonium group, acetylcholine does not penetrate lipid membranes.

NH4+.

they form insoluble quaternary ammonium salts
I know that quaternary ammonium salts can be used as fabric softeners. There are many more uses but for a level chemistry just the one use should be enough so long as it is fairly common.
Cationic detergents are the quaternary ammonium salt of acetates, chlorides or bromides. For example, alkyl trimethyl ammonium bromide
Yes, it is. It's a quaternary ammonium salt with a long carbon chain.
No, ligands are those which may donate pairs of electrons to a metal ion quaternary salts of nitrogen do not have free electrons pairs.
An acyliminium is an acyl iminium ion - an ion of iminium, a form of quaternary ammonium formed by an imine.
