Choline (commonly in the form of Choline chloride) is one of the B categories of vitamin. It is acetylcholine in the biological organization. It is the components of lecithin and nerve acid fat. It is used by most animals as a precursor of acetyl choline, which influences the transmission of impulses from nerves to muscles. It is also used as a source of methyl groups. In feed, the content of natural choline chloride is limited. It can not satisfy complete demand for the animal growing. Therefore, choline chloride is widely used as feed additive at home and abroad. It will stimulate the animal or poultry's growth, put on their weight rapidly and boost up the body's immunity function. It has prominence effects on improving the quality and quantity of eggs and meat. On the contrary, shortage of choline may cause liver diseases, retarded growth, perosis, reduced egg-laying rate and increased mortality.
Choline chloride is an organic compound and a quaternary ammonium salt. It has a choline cation with chloride anion. Alternative names are hepacholine, biocolina and lipotril.
Choline chloride is mass-produced and is an important additive in feed especially for chickens where it accelerates growth. With urea it forms a deep eutectic solvent. Other commercial choline salts are choline hydroxide and choline bitartrate. In foodstuffs the compound is often present as phosphatidylcholine.
Chemical properties: White crystalline.
Melting point 240 ° C. Soluble in water and alcohol, almost shows neutral aqueous solution, insoluble in ether, and petroleum ether, benzene and carbon disulfide. Tiny have fish foul smell, salty, bitter taste, easy to ChaoXie, in alkali solution is not stable.
Used in the treatment of fatty liver and cirrhosis, also used for feed additive, can stimulate ovarian prolific eggs, breed and livestock, fish and weight gain.
