N,N-Dimethylglycine

개요N,N-Dimethylglycine (DMG) is a N-methylated product of the amino acid glycine. It is found in beans and liver. It can be formed from trimethylglycine upon the loss of one of its methyl groups. It is also a byproduct of the metabolism of choline. When DMG was first discovered, it was referred to as vitamin B16, but, unlike true B vitamins, deficiency of DMG in the diet does not lead to any ill-effects meaning it does not meet the definition of a vitamin. It is used in comparative analysis with other N-methylated glycines. N,N-Dimethylglycine is used in the development of glycine-based ionic liquids and emulsifiers, and as a substrate to identify, differentiate and characterize amino acid methyltransferase(s). It is potentially useful as a biomarker of protein degradation in COPD patients.

역사N,N-Dimethylglycine was discovered in 1943. It is found in some but not all formulations of pangamic acid (vitamin B15). Pangamic acid has been sold as a dietary supplement in the United States at least since the late 1970s, when the lay press celebrated its benefits. Although pangamic acid is also known as vitamin B16, it is not actually a vitamin because no deficiency state has been identified, and it has no known nutritional value.

용도N,N-Dimethylglycine is used as an athletic performance enhancer and immunostimulant. It is also used in the treatment of autism, epilepsy and mitochondrial disease. It is also employed as a biomarker of protein degradation in chronic obstructive lung disease (COPD) patients. Further, it is used as a substrate to identify, differentiate and characterize amino acid methyltransferase. It plays an important role for the development of glycine-based ionic liquids and emulsifiers.
