A betaine (/ ˈbiːtə.iːn, bɪˈteɪ -, - ɪn /) in chemistry is any neutral chemical compound with a positively charged cationic functional group that bears no hydrogen atom, such as a quaternary ammonium or phosphonium cation (generally: onium ions), and with a negatively charged functional group, such as a carboxylate group that may not be adjacent...

2024年11月11日 · Betaine works by preventing the build-up of an amino acid called homocysteine. This amino acid can harm blood vessels and contribute to heart disease, stroke, or circulation problems. Betaine is used to reduce homocysteine levels in people with a genetic condition called homocystinuria, in which the amino acid builds up in the body.

Betaine is a methyl group donor that functions in the normal metabolic cycle of methionine. It is a naturally occurring choline derivative commonly ingested through diet, with a role in regulating cellular hydration and maintaining cell function.

Betaine’s role in preventing/attenuating both alcohol-induced and metabolic-associated liver diseases has been well studied and is extensively reviewed here. Several studies show that betaine protects against the development of alcohol-induced hepatic steatosis, apoptosis, and accumulation of damaged proteins.

2003年11月19日 · Betaine is distributed widely in animals, plants, and microorganisms, and rich dietary sources include seafood, especially marine invertebrates (≈1%); wheat germ or bran (≈1%); and spinach (≈0.7%). The principal physiologic role of betaine is as an osmolyte and methyl donor (transmethylation).

2018年5月23日 · Betaine is known as trimethylglycine and is widely distributed in animals, plants, and microorganisms. Betaine is known to function physiologically as an important osmoprotectant and methyl group donor. Accumulating evidence has shown that betaine has anti-inflammatory functions in numerous diseases.

2015年5月15日 · Betaine is widely distributed in plants and animals and has a role as an osmolyte and as a cofactor in methylation in liver metabolism. It has been shown to protect internal organs, improve vascular risk factors and enhance performance. The growing body of evidence shows that betaine is an important nutrient for the prevention of chronic disease.

Betaine (trimethyl glycine) is a metabolite formed in the body from choline. It is a natural constituent of beets, broccoli, grains, shellfish, spinach, and marine algae.
