General description

Betaine is a quaternary ammonium zwitterion, extensively present in animals, plants and microorganisms. It also forms a good dietary source as it is found in wheat, spinach, shellfish and sugar beets. Betaine is a methyl derivative of the amino acid glycine. It is known by different names such as trimethylglycine, glycine betaine, lycine and oxyneurine.


Betaine has been used to study the effects of antioxidants on regrowth from cryopreservation.

Biochem/physiol Actions

Apart from betaine taking part in transmethylation, it acts as an organic osmolyte in protecting cells under stress. This is being significantly observed in plants and microorganisms. Betaine is also known to increase the levels of S-adenosylmethionine and thus this might reduce the effects of hepatic steatosis.
End-product of oxidative metabolism of choline, betaine is a general methyl donor, in particular in a minor pathway of methionine biosynthesis. It is used to treat homocystinuria, which is a defect in the major pathway of methionine biosynthesis.

Brucellosis remains an important anthropozoonosis worldwide. Brucella species are genetically homogeneous, and thus, the typing of Brucella species for epidemiological purposes by conventional molecular typing methods has remained elusive. Although many methods could segregate isolates into the phylogenetically recognized taxa...

High pressure carbon dioxide (HPCD) treatment is currently considered as an attractive non-thermal process for preserving food. Industrial application of this technique requires, among others, systematic (quantitative) data on the inactivation of food relevant pathogenic and spoilage microorganisms, and in-depth...

High plasma concentrations of homocysteine may increase risk of cardiovascular disease. Folic acid lowers plasma homocysteine by 25% maximally, because 5-methyltetrahydrofolate is a methyl donor in the remethylation of homocysteine to methionine. Betaine (trimethylglycine) is also a methyl donor in...

The full potential of diagnostic PCR is limited, in part, by the presence of inhibitors in complex biological samples that reduce the amplification efficiency. Therefore, different pre-PCR treatments are being used to reduce the effects of PCR inhibitors. The aim...
