چکیده

This study was performed to examine the effect of dietary level of vitamin B6 on the concentrations of carnosine and anserine, antioxidants, in the heart of rats. Analysis using UPLC-MS/MS showed that the concentrations of these dipeptides in the 7 and 35 mg pyridoxine HCl/kg groups were significantly higher than those in the 1 mg pyridoxine HCl/kg group, implying the novel role of dietary vitamin B6 as a determinant of the dipeptides favorable for heart.

Carnosine Content in Skeletal Muscle Is Dependent on Vitamin B6 Status in Rats

Carnosine, a histidine-containing dipeptide, is well known to be associated with skeletal muscle performance. However, there is limited information on the effect of dietary micronutrients on muscle carnosine level. Pyridoxal 5'-phosphate (PLP), the active form of vitamin B6, is involved in amino acid metabolisms in the body as a cofactor. We hypothesized that enzymes involved in β-alanine biosy...

Effect of dietary methionine level on anserine and carnosine contents in the gastrocnemius muscle of rat.

Anserine and carnosine in the muscle of growing rats were measured to explore the effect of dietary methionine. Carnosine was reduced in the gastrocnemius muscle of rats fed on a methionine-free diet. After refeeding on methionine for one week, carnosine in the muscle approached to the normal level. In contrast, anserine increased in the muscle of rats fed on a methionine-free diet. Anserine al...

Effect of Dietary Supplementation of Blood Meal and Additional Magnesium on Carnosine and Anserine Concentrations of Pig Muscles

The objective of this study was to investigate the effect of dietary supplementation of blood meal as a source of L-histidine, and the addition of magnesium (Mg) as a catalyst of carnosine synthetase for the carnosine and anserine concentrations of pig muscles (longissimus dorsi, LD and vastus intermedius, VI). A total of twenty-four pigs with an average body weight of 60.2±4.2 kg were randomly...

Concentrations of creatine, creatinine, carnosine, and anserine in bovine longissimus muscle and their correlations with carcass and palatability traits

Creatine and carnosine have been considered as valuable nutraceuticals in meat products for a long time. Creatine as energy buffer plays an important role in cellular metabolism and shows protective effects in neurodegenerative diseases such as Parkinson’s disease and Huntington’s disease. Carnosine has multiple physiological functions associated with anti-oxidation and anti-aging. Although cre...

Effects of anserine on the renal sympathetic nerve activity and blood pressure in urethane-anesthetized rats.

Previous studies have demonstrated that central injection of L-carnosine (beta-alynyl-L-histidine), dipeptide synthesized in mammalian muscles, affects renal sympathetic nerve activity (RSNA) and blood pressure (BP) in anesthetized rats. In the present study, using urethane-anesthetized rats, we examined the dose-dependent effects of intravenous (IV) injection of various doses of anserine, dipe...
