DescriptionBetaine (glycine betaine or trimethylglycine) is a methylated derivative of glycine synthetized from choline. It is a very efficient osmolyte found in a wide range of bacteria and plants, where it is accumulated at high cytoplasmic concentrations in response to osmotic stress, to act as an osmoprotectant. Many organisms, including fungi, are also able to catabolize glycine betaine, using it as a sole source for both carbon and nitrogen. [Biocyc PWY-3721 and PWY-3661]
