L-Citrulline Improves Splanchnic Perfusion and Reduces Gut Injury during Exercise

Medicine & Science in Sports & Exercise, 2014
Splanchnic hypoperfusion is a physiological phenomenon during strenuous exercise. It has been associated with gastrointestinal symptoms and intestinal injury and may hamper athletic performance. We hypothesized that L-citrulline supplementation improves splanchnic perfusion and decreases intestinal injury by enhancing arginine availability.

The crystal and molecular structure of L-citrulline hydrochloride

Acta Crystallographica Section B Structural Crystallography and Crystal Chemistry, 1971
The crystal of L-citrulline hydrochloride C6H13N3O3. HCI,has been determined using three-dimensional photographic data. The crystals are monoclinic, space group C2, with cell dimensinos a=17.86, b=5.09, c=11.77 A and β=106.8°. Refinement was carried out with full-matrix least-squares methods, including anisotopic thermal parameters foe all non-hydrogen

Lactobacillus murinus alleviates insulin resistance via promoting L-citrulline synthesis

Journal of Endocrinological Investigation
The role of Lactobacillus murinus as a potential probiotic is being explored. Our objectives were to explore the effects of Lactobacillus murinus on insulin resistance and the underlying mechanism.Insulin resistance animal models were applied to study the effect of L. murinus and the underlying mechanism by six weeks of treatment.

Recycling of l-citrulline to sustain nitric oxide-dependent enteric neurotransmission

Neuroscience, 1995
Neurons that synthesize nitric oxide from arginine produce stoichiometric amounts of citrulline. We investigated whether nitric oxide-releasing enteric neurons have the capacity to recycle citrulline to arginine and thereby sustain nitrergic neurotransmission.

One Week of L-Citrulline Supplementation Improves Performance in Trained Cyclists

Journal of Strength and Conditioning Research, 2019
Abstract Stanelle, ST, McLaughlin, KL, and Crouse, SF. One week of L-citrulline supplementation improves performance in trained cyclists. J Strength Cond Res 34(3): 647–652, 2020—L-citrulline (CIT) is a nonessential amino acid that is touted as an ergogenic aid for athletic performance because of its purported ability to stimulate nitric ...

Transport of L-citrulline in neural cell cultures.

Developmental neuroscience, 2001
Uptake of L-[(14)C]citrulline was studied in cell culture models of the main neural cell populations, in astroglia-rich primary cultures derived from neonatal rat brain, in rat glioma cells C6-BU-1, in cells of the murine microglial clone N11 and in the glioma x neuroblastoma hybrid cell line 108CC15 with neuronal properties.

Decreased serum L-arginine and L-citrulline levels in major depression

Psychopharmacology, 2017
It has been suggested that endothelial dysfunction caused by a decreased endothelial production of nitric oxide (NO) may contribute to the consistently observed increased risk of developing cardiovascular disease (CVD) in physically healthy patients suffering from major depression (MD).

Metabolic capacity for l-citrulline synthesis from ammonia in rat isolated colonocytes

Biochimica et Biophysica Acta (BBA) - General Subjects, 1999
Ammonia is present at high concentration in the colon lumen and is considered a colon cancer suspect. Furthermore, ammonia usually eliminated by the liver in the ornithine cycle is considered highly toxic to cerebral function when present in excess in the blood plasma. Therefore, the metabolic pathways involved in ammonia metabolism in colonocytes were

l-Citrulline recycling by argininosuccinate synthetase and lyase in rat gastric fundus

European Journal of Pharmacology, 2002
The aim of this study was to investigate in rat gastric fundus whether L-citrulline, the co-product in the nitric oxide (NO) biosynthesis catalyzed by neuronal nitric oxide synthase (nNOS), can be converted back to the nNOS substrate L-arginine. Immunohistochemistry showed that argininosuccinate synthetase and argininosuccinate lyase, that mediate ...
