CLASSIFICATION

  

GENERAL DESCRIPTION

BETAINE, (also called Trimethylglycine Or Oxyneurine), is naturally found in the metabolism of oxidation of choline. It, chemically 2-(Trimethylammonio)ethanoic acid, hydroxide, inner salt, donates a methyl group to homocysteine to produce Dimethylglycine and Methionine, which results a reduction in potentially toxic homocysteine levels. Synthesis of betaine in body tissue may not be high enough to meet the betaine needs of the animal, especially under stressful conditions.  It is considered as a provitamin. It is an essential supplement in the feed industry. Commercially, synthetic betaine is available as anhydrous betaine (no water of crystallization) , Betaine monohydrate ( with water of hydration) and a stable salt form of Betaine monohydrochloride (with 25% hydrochloride to preserve betaine from degradation in storage and acts as an acidifier in applications).
