Background: A low level of L-glutamine, a precursor of nicotinamide adenine dinucleotide (NAD) in red blood cells (RBCs), is identified as an underlying mechanism for the potential decrement of the NAD redox and the incidence of pain crisis in sickle cell anemia (SCA). The aim of this study is to assess the impact of oral L-glutamine therapy on pain crisis reduction in patients with SCA and sic...

experiment was conducted to evaluate the effect of l-glutamine on coated sperm freezing by using four rams. semen was collected by artificial vagina contact with a tube containing tris-fructose-egg yolk 15%. samples were pooled and centrifuged. after removing supernatant and diluting pellet, samples were split into 5 equal part and added 0, 40, 80, 120 and 160 mm l-glutamine. samples were froze...

background: the present study was conducted to investigate the possible effects of l-carnitine and glutamine and their synergistic effects on male soccer athletes. methods: 28 male soccer players (21.1 ± 0.7 y) were enrolled in a randomized pre and post intervention, double-blind design. before the intervention, their performances were assessed by bruce protocol, and their body composition was ...

Amino acid dehydrogenases (L-amino acid: oxidoreductase deaminating EC 1.4.1.X) are members of the wider superfamily of oxidoreductases that catalyze the reversible oxidative deamination of an amino acid to its keto acid and ammonia with the concomitant reduction of either NAD+, NADP+ or FAD. These enzymes have been received much attention as biocatalysts for use in biosensors or diagnostic kit...

to determine the effect of different levels of l-glutamine and glycerol on freezing coated sperm, semen were collected from 4 taleshi rams through artificial vagina contact with a tube containing tris-fructose-egg yolk 15%. ejaculates were pooled, centrifuged and supernatant was removed, then cell fractions were used. samples were split into 9 equal parts and 3 (g3), 5 (g5) or 7% (g7) glycerol ...

the stability constants and complexation reaction between l-glutamine, l-arginine andglycine with zn (ii) , co (ii) and ni (ii) were studied potentiometrically in aqueous solution at25° c and μ=0.1 m kno3. the overall stability constants log β´s of all species are obtained bycomputer refinement of ph-volume data using best computer program. several models weretested and the lowest δfit, the bes...

A pathway from enteral L-glutamine as substrate for L-arginine synthesis is suggested by previous studies. L-Glutamine and L-glutamine dipeptides exhibit numerous beneficial effects in experimental and clinical studies. In trauma patients, enteral L-glutamine supply increased plasma L-arginine. The present study was designed to quantify the contribution of L-glutamine to the de novo L-citrullin...
