Chemical Information
FooDB NameL-ornithine
DescriptionOrnithine, 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.
