Common Name

Ornithine

Description

Ornithine, also known as (S)-ornithine, belongs to the class of organic compounds known as l-alpha-amino acids. These are alpha amino acids which have the L-configuration of the alpha-carbon atom. Ornithine is a drug which is used for nutritional supplementation, also for treating dietary shortage or imbalance. it has been claimed that ornithine improves athletic performance, has anabolic effects, has wound-healing effects, and is immuno-enhancing. Ornithine is a very strong basic compound (based on its pKa). Ornithine exists in all living species, ranging from bacteria to humans. Within humans, ornithine participates in a number of enzymatic reactions. In particular, carbamoyl phosphate and ornithine can be converted into citrulline; which is mediated by the enzyme ornithine carbamoyltransferase, mitochondrial. In addition, ornithine and urea can be biosynthesized from L-arginine; which is mediated by the enzyme arginase-1. In humans, ornithine is involved in the metabolic disorder called argininemia. Outside of the human body, Ornithine has been detected, but not quantified in, several different foods, such as lemon thymes, black elderberries, tronchuda cabbages, black mulberries, and bilberries. This could make ornithine a potential biomarker for the consumption of these foods. Ornithine is a potentially toxic compound. Ornithine, with regard to humans, has been found to be associated with several diseases such as ulcerative colitis, myopathy, lactic acidosis, and sideroblastic anemia 1, and perillyl alcohol administration for cancer treatment; ornithine has also been linked to several inborn metabolic disorders including hyperdibasic aminoaciduria I and ornithine transcarbamylase deficiency. An optically active form of ornithine having L-configuration. Ornithine is expected to be in Cannabis as all living plants are known to produce and metabolize it.

Specific function:: Not Available
Gene Name:: ODC1
Uniprot ID:: P11926
Molecular weight:: 51147.73

Enzyme Details

8. Arginase-2, mitochondrial

General function:: Involved in arginase activity
Specific function:: May play a role in the regulation of extra-urea cycle arginine metabolism and also in down-regulation of nitric oxide synthesis. Extrahepatic arginase functions to regulate L-arginine bioavailability to NO synthase. Since NO synthase is found in the penile corpus cavernosum smooth muscle, the clitoral corpus cavernosum and the vagina, arginase II plays a role in both male and female sexual arousal. It is therefore a potential target for the treatment of male and female sexual arousal disorders.

Molecular weight:: 71672.2

Enzyme Details

7. Y+L amino acid transporter 2

General function:: Involved in transport
Specific function:: Involved in the sodium-independent uptake of dibasic amino acids and sodium-dependent uptake of some neutral amino acids. Requires co-expression with SLC3A2/4F2hc to mediate the uptake of arginine, leucine and glutamine. Also acts as an arginine/glutamine exchanger, following an antiport mechanism for amino acid transport, influencing arginine release in exchange for extracellular amino acids. Plays a role in nitric oxide synthesis in human umbilical vein endothelial cells (HUVECs) via transport of L-arginine. Involved in the transport of L-arginine in monocytes. Reduces uptake of ornithine in retinal pigment epithelial (RPE) cells
Gene Name:: SLC7A6
Uniprot ID:: Q92536
Molecular weight:: 56826.9
