Potential nutritional and physiological functions of betaine in livestock.
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...
متن کاملPhysiological functions should be considered as true end points of nutritional intervention studies.
With the beginning of this millennium it has become fashionable to only follow 'evidence-based' practices. This generally-accepted approach cruelly negates experience or intelligent interpretation of pathophysiology. Another problem is that the great 'meta-analysts' of the present era only accept end points that they consider 'hard'. In the metabolic and nutritional field these end points are i...
متن کاملAdsorption of Vitamin C on a Fullerene Surface: DFT Studies
Density functional theory (DFT) calculations were performed to investigate adsorptions of vitamin C (Vit) on the surface a fullerene structure (Ful) in gaseous and water–solvated systems. Two models of Vit including OVit and MVit were created based on the original structure of Vit for OVit and methylation of all hydroxyl groups for MVit. All singular and hybrid structures were optimized and the...
متن کاملStudies on the Nutritional and Physiological Implications of Sugar Alcohols in Cecectomized Rats
Indigestible but fermentable materials are widely used in the world mainly as sugar substitute for their many functional effects in nutrition and disease prevention. The appropriate evaluation of the functional effects of the above materials is very important before their application for consumption by human beings. It is sure that a wide range study of the effects of above materials directly i...
متن کاملStudies on Interrelation of Vitamin A Deficiency and Bladder Stones Formation
Serum Vitamin A, total protein, serum electrophoresis, were determined in pediatric patients with urolithiasis (mostly bladder stones) and compared to that of normal healthy volunteers. The level of Vitamin A in healthy volunteers was found to be significantly (P<0.001) higher than that of patients with urolithiasis. The amount of total serum protein, however, was not significantly different i...
