Cataloguing guanidinoacetic acid content in various foods
International Journal for Vitamin and Nutrition Research, 2022Abstract. Guanidinoacetic acid (GAA) is a natural amino acid derivative involved in several metabolic pathways across the human body, including creatine biosynthesis, arginine utilization, and neuromodulation. Apart from GAA synthesized internally from glycine and arginine, a total daily exposure to GAA also involves exogenous dietary sources. However,

Animal Feed Science and Technology, 2015
Abstract This work sought to evaluate the effects of guanidinoacetic acid (GAA) and combination of GAA and betaine on postmortem glycolysis and meat quality of finishing pigs. A total of 180 cross-bred, castrated male pigs were randomly assigned to one of three experimental diets (pigs were adapted to the control diet for 7 days and experimental ...

The Lack of Effect of Guanidinoacetic Acid on in vitro Osmotic Fragility of Erythrocytes
Nephron, 2008Serum levels of guanidinoacetic acid (GAA) were measured in 22 patients on maintenance hemodialysis prior to dialysis. The mean level was 0.699 ± 0.25 mg/dl, which represents a 3-fold increase above normal. Addition of GAA to blood from normal volunteers and incubation for 3 and 48 h at 37°C did not influence osmotic fragility of erythrocytes in vitro.

An alternative mechanism for guanidinoacetic acid to affect methylation cycle
Medical Hypotheses, 2014Guanidinoacetic acid (also known as glycocyamine; GAA) is an endogenous substance which occurs in humans and plays a central role in the biosynthesis of creatine. The formation of creatine from GAA consumes methyl groups, and increases production of homocysteine. GAA may have the potential to stimulate insulin secretion.

Nephron, 2008
Most chronic renal failure (CRF) patients show low serum concentrations of guanidinoacetic acid (GAA). In this study, the author investigated the impaired metabolism of GAA in CRF focusing on the transformation of arginine (Arg) to GAA by analyzing CRF rabbits using 14C-Arg.

Urinary Guanidinoacetic Acid Excretion in Gentamicin Nephrotoxicity
1985Bonas et al. reported in 1963 that four patients with kidney disease were shown to excrete markedly decreased amounts of guanidinoacetic acid (GAA) in their urine1.

We have already reported that renal glycine amidinotransferase (GAT) activity decreases in the course of renal damage, however, the inability of the kidney to synthesize guanidinoacetic acid (GAA) may be compensated by the pancreas in a more advanced stage of renal failure, and that in diabetes mellitus, the production of GAA is decreased from the ...

Biosynthesis of Guanidinoacetic Acid in Isolated Rat Hepatocytes
1985Guanidinoacetic acid (GAA), a precursor of creatine, is formed from arginine and glycine by transamidinationl. GAA formation in rat is not detected in liver homogenates2 or in isolated perfused livers3. Therefore, creatine synthesis in rat liver is regulated by the activity of transamidinase in the kidney4.
