Choline chloride

Chemical properties

White crystalline powder

The Uses of Choline chloride

Choline chloride helps in providing nourishment for pig feed and poultry feed. It acts as a food flavor enhancer. It is used as a precursor of acetylcholine and is a methyl donor in various metabolic processes and in lipid metabolism.

The Uses of Choline chloride

choleretic, lipotropic, hepatoprotectant

What are the applications of Application

Choline chloride has been used:
as a component of choline acetyltransferase (ChAT) buffer and for choline uptake in cultured human neuroblastoma (SK-N-SH) cells
for choline standard curve generation for quantifying phospholipase D (PLD) activity
as a component of slice solution for the dissection of entorhinal-hippocampal brain slices

Definition

ChEBI: Choline chloride is a quaternary ammonium salt with choline cation and chloride anion. It has a role as an animal growth promotant. It is a chloride salt and a quaternary ammonium salt. It contains a choline.

Preparation

Choline chloride can be made by treating trimethylamine with 2-chloroethanol.

(CH3)3N + ClCH2CH2OH → [(CH3)3NCH2CH2OH]+Cl?

General Description

Choline chloride appears as white crystals. Practically neutral aqueous solution(NTP, 1992). It is a basic constituent of lecithin that is found in many plants and animal organs. It is important as a precursor of acetylcholine, as a methyl donor in various metabolic processes, and in lipid metabolism.

Air & Water Reactions

Deliquescent. Very soluble in water.

Reactivity Profile

An acidic organic salt. Materials in this group are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.

Fire Hazard

Choline chloride is relatively nonflammable.

Biochem/physiol Actions

The enzymatic activities of butyrylcholinesterase (BChE) and paraoxonase 1 (PON1), two serum enzymes synthesized by the liver and related with inflammation, were decreased in a sepsis animal model injected with LPS. Choline chloride administered intravenously at 20 mg/kg body weight prevents the LPS-mediated decreases in the activities of these two enzymes .

Safety Profile

Poison by intraperitoneal and intravenous routes. Moderately toxic experimentally by ingestion and subcutaneous routes. Mutation data reported. A lipotropic agent which induces the reduction in fats contained in the liver. When heated to decomposition it emits toxic fumes of Cl-, SOx and NOx. See also CHOLINE.

Purification Methods

Extremely deliquescent. Check purity by AgNO3 titration or by titration of OH-base after passage through an anion-exchange column. Crystallise it from absolute EtOH, or EtOH/Et2O, dry it under vacuum and store it in a vacuum desiccator over P2O5 or Mg(ClO4)2. [Beilstein 4 IV 1443.]
