Arginine is synthesized from citrulline in the urea cycle by the sequential action of the cytosolic enzymes argininosuccinate synthetase and argininosuccinate lyase. This is an energetically costly process, because for each molecule of argininosuccinate that is synthesized, one molecule of adenosine triphosphate (ATP) is hydrolyzed to adenosine ...

Nitric oxide synthases produce NO by catalysing a five-electron oxidation of a guanidino nitrogen of L-arginine (L-Arg). Oxidation of L-Arg to L-citrulline occurs via two successive monooxygenation reactions producing N ω-hydroxy-L-arginine (NOHLA) as an intermediate. 2 mol of O 2 and 1.5 mol of NADPH are consumed per mole of NO formed.

Arginine and proline metabolism is one of the central pathways for the biosynthesis of the amino acids arginine and proline from glutamate. The pathways linking arginine, glutamate, and proline are bidirectional. Thus, the net utilization or production of these amino acids is highly dependent on cell type and developmental stage.
Arginine vasotocin (AVT), a hormone produced by neurosecretory cells within the posterior pituitary gland (neurohypophysis) of the brain, is a major endocrine regulator of water balance and osmotic homoeostasis and is involved in social and sexual behavior in non-mammalian vertebrates. In mammals, it appears to have biological properties ...
Creatine is synthesized predominantly in the kidney and liver, by a two-step enzymatic process. In the first step, glycine and arginine are combined by arginine:glycine amidinotransferase (AGAT) to form guanidinoacetate. This step also results in the production of ornithine. Creatine is produced by the enzyme guanidinoacetate methyltransferase ...
As for the orgasm connection, oxytocin is produced in the hypothalamus (i.e., the control center of the brain), which is yet another region activated—both in the posterior and anterior—during ...
N-Acetylglutamic acid is the second intermediate in the arginine production pathway in Escherichia coli and is produced via NAGS. [5] In this pathway, N-acetylglutamic acid kinase (NAGK) catalyzes the phosphorylation of the gamma (third) carboxyl group of N-acetylglutamic acid using the phosphate produced by hydrolysis of adenosine triphosphate ...
