The present review summarises the potential nutritional and physiological functions of betaine as a feed additive in relation to performance criteria in livestock production. Betaine, the trimethyl derivative of the amino acid glycine, is a metabolite of plant and animal tissues. In plants, betaine is particularly synthesised and accumulated as an osmoprotectant against salt and temperature str...

The blockade of spin& glycine receptors with intrathecal strychnine produces a reversible allodynia-like state in the rat. Thus, hair deflection, in the presence of intrahecal strychmine, induces cardiovascular and motor withdrawal responses comparable with those evoked by noxious thermal, mechanical, or chemical stimulation in the absence of strychnine. Bn the present study, we mapped the cuta...

Methyltransferases play crucial roles in many cellular processes, and various regulatory mechanisms have evolved to control their activities. For methyltransferases involved in biosynthetic pathways, regulation via feedback inhibition is a commonly employed strategy to prevent excessive accumulation of the pathways' end products. To date, no biosynthetic methyltransferases have been characteriz...

Betaine aldehyde dehydrogenase (BADH) catalyzes the last step in the synthesis of the glycine betaine from choline. The BADH gene from turfgrass Ophiopogon japonicus has not been reported. In this study, we first isolated the full length cDNA of betaine aldehyde dehydrogenase gene (OjBADH) from O. japonicus using Reverse TranscriptasePolymerase Chain Reaction (RT-PCR) and Rapid Amplification of...

Homocysteine is a risk factor for vascular diseases, and lowering of plasma total homocysteine (tHcy) may be beneficial for health. Homocysteine can be remethylated to methionine by betaine-homocysteine methyltransferase using betaine (2(N,N,N-trimethyl)glycine) as methyl donor. A dose of 6 g betaine/d has been used in the treatment of homocystinuria, but data on the dose-response are scarce. T...

Urea in renal medullas is sufficiently high to perturb macromolecules, yet the cells survive and function. The counteracting osmolytes hypothesis holds that methylamines, such as glycine betaine (betaine) and glycerophosphocholine (GPC) in renal medullas, stabilize macromolecules and oppose the effects of urea. Although betaine counteracts effects of urea on macromolecules in vitro and protects...

The growth of Listeria monocytogenes ATCC 23074 in defined medium is sensitive to high osmolarity when compared with its growth in complex media, such as brain heart infusion (BHI). The two major contributors to this difference in growth rate are the availability in BHI of the osmoprotectant glycine betaine and peptides. Peptone plays two major roles: firstly as a nutritional supplement for pro...
