Depolarization may be prolonged due to succinylcholines. Choline is the precursor for the neurotransmitter acetylcholine which is involved in many functions including memory and muscle control.

Functional Groups
Choline is a quaternary saturated amine with the chemical formula c 5 h 14 no or ch 3 3 n ch 2 ch 2 ohx where x is a counterion such as chloride hydroxide or tartrate.
Choline functional group. Therefore all plant and animal cells need choline to preserve their structural integrity 12. The body needs choline to synthesize phosphatidylcholine and sphingomyelin two major phospholipids vital for cell membranes. A functional group makes up part of a larger molecule.
Functional groups are specific atoms ions or groups of atoms having consistent properties. Originally referring to an endogenous compound that is formed in specialized organ or group of cells and carried to another organ or group of cells in the same organism upon which it has a specific regulatory function the term is now commonly used to include non endogenous semi synthetic and fully synthetic analogues of such compounds. These parts of organic molecules are called functional groups.
Choline is a source of methyl groups needed for many steps in metabolism. Succinylcholine binds to nicotinic receptors at the neuromuscular junction and opening the ligand gated channels in the same way as acetylcholine resulting in depolarization and inhibition of neuromuscular transmission. The identification of functional groups and the ability to predict reactivity based on functional group properties is one of the cornerstones of organic chemistry.
The cation appears in the head groups of phosphatidylcholine and sphingomyelin two classes of phospholipid that are abundant in cell membranes. Amines are organic compounds and functional groups that contain a basic nitrogen atom with a lone pair. Succinylcholine is a quaternary ammonium compound and depolarizing agent with short term muscle relaxant properties.
