L-Ornithine
Ornithine, also known as (S)-2,5-diaminopentanoic acid or ornithine, (L)-isomer, is a member of the class of compounds known as L-alpha-amino acids. L-alpha-amino acids are alpha amino acids which have the L-configuration of the alpha-carbon atom. Ornithine is soluble (in water) and a moderately acidic compound (based on its pKa). Ornithine can be found in a number of food items such as pine nut, lingonberry, turnip, and cassava, which makes ornithine a potential biomarker for the consumption of these food products. Ornithine can be found primarily in most biofluids, including urine, cerebrospinal fluid (CSF), feces, and saliva, as well as throughout most human tissues. Ornithine exists in all living species, ranging from bacteria to humans. In humans, ornithine is involved in few metabolic pathways, which include arginine and proline metabolism, glycine and serine metabolism, spermidine and spermine biosynthesis, and urea cycle. Ornithine is also involved in several metabolic disorders, some of which include ornithine transcarbamylase deficiency (OTC deficiency), prolidase deficiency (PD), citrullinemia type I, and arginine: glycine amidinotransferase deficiency (AGAT deficiency). Moreover, ornithine is found to be associated with cystinuria, alzheimers disease, leukemia, and uremia. Ornithine is a non-carcinogenic (not listed by IARC) potentially toxic compound. 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 non-proteinogenic amino acid that plays a role in the urea cycle. Ornithine is abnormally accumulated in the body in ornithine transcarbamylase deficiency. The radical is ornithyl . L-Ornithine is metabolised to L-arginine. L-arginine stimulates the pituitary release of growth hormone. Burns or other injuries affect the state of L-arginine in tissues throughout the body. As De novo synthesis of L-arginine during these conditions is usually not sufficient for normal immune function, nor for normal protein synthesis, L-ornithine may have immunomodulatory and wound-healing activities under these conditions (by virtue of its metabolism to L-arginine) (DrugBank). Chronically high levels of ornithine are associated with at least 9 inborn errors of metabolism including: Cystathionine Beta-Synthase Deficiency, Hyperornithinemia with gyrate atrophy, Hyperornithinemia-hyperammonemia-homocitrullinuria syndrome, Hyperornithinemia-hyperammonemia-homocitrullinuria syndrome, Hyperprolinemia Type II, Lysinuric Protein Intolerance, Ornithine Aminotransferase Deficiency, Ornithine Transcarbamylase Deficiency and Prolinemia Type II (T3DB). Ornithine or L-ornithine, also known as (S)-2,5-diaminopentanoic acid is a member of the class of compounds known as L-alpha-amino acids. L-alpha-amino acids are alpha amino acids which have the L-configuration of the alpha-carbon atom. L-ornithine is soluble (in water) and a moderately basic compound. Ornithine is a non-proteinogenic amino acid that plays a role in the urea cycle. It is considered to be a non-essential amino acid. A non-essential amino acid is an amino acid that can be synthesized from central metabolic pathway intermediates in humans and is not required in the diet. L-Ornithine is one of the products of the action of the enzyme arginase on L-arginine, creating urea. Therefore, ornithine is a central part of the urea cycle, which allows for the disposal of excess nitrogen. Outside the human body, L-ornithine is abundant in a number of food items such as wild rice, brazil nuts, common oregano, and common grapes. L-ornithine can be found throughout most human tissues; and in most biofluids, some of which include blood, urine, cerebrospinal fluid (CSF), sweat, saliva, and feces. L-ornithine exists in all living species, from bacteria to plants to humans. L-Ornithine is also a precursor of citrulline and arginine. In order for ornithine that is produced in the cytosol to be converted to citrulline, it must first cross the inner mitochondrial membrane into the mitochondrial matrix where it is carbamylated by the enzyme known as ornithine transcarbamylase. This transfer is mediated by the mitochondrial ornithine transporter (SLC25A15; AF112968; ORNT1). Mutations in the mitochondrial ornithine transporter result in hyperammonemia, hyperornithinemia, homocitrullinuria (HHH) syndrome, a disorder of the urea cycle (PMID: 16256388). The pathophysiology of the disease may involve diminished ornithine transport into mitochondria, resulting in ornithine accumulation in the cytoplasm and reduced ability to clear carbamoyl phosphate and ammonia loads (OMIM 838970). In humans, L-ornithine is involved in a number of other metabolic disorders, some of which include, ornithine transcarbamylase deficiency (OTC deficiency), argininemia, and guanidinoacetate methyltransferase deficiency (GAMT deficiency). Ornithine is abnormally accumulated in the body in ornithine transcarbamylase deficiency. Moreover, Ornithine is found to be associated with cystinuria, hyperdibasic aminoaciduria I, and lysinuric protein intolerance, which are inborn errors of metabolism. It has been claimed that ornithine improves athletic performance, has anabolic effects, has wound-healing effects, and is immuno-enhancing. L-Ornithine. CAS Common Chemistry.

6-Hydroxyhexanoic acid
6-Hydroxyhexanoate was identified as the immediate product of hexanoate w-hydroxylation by whole cells and was further oxidized into adipic acid and an unexpected metabolite identified as 2-tetrahydrofuranacetic acid. This same metabolite, together with adipic acid, was also detected when similarly induced cells were incubated with hexanoate or 1,6-hexanediol, but not with 6-oxohexanoate (adipic semialdehyde).Cells grown on hexanoate and incubated with 6-hydroxyhexanoate were also found to accumulate 2-tetrahydrofuranacetic acid, which was not further degraded. Utilization of 6-hydroxyhexanoate for growth was restricted to those organisms also able to utilize adipate. Similar observations were made with 1,6-hexanediol serving as the carbon source and cells obtained from one organism,Pseudomonas aeruginosa PAO, grown either on 1,6-hexanediol or 6-hydroxyhexanoate,were found to be well induced for both 6-oxohexanoate and adipate oxidation. The results indicate that 6-hydroxyhexanoate and 1,6-hexanediol are susceptible to both 1B- and w-oxidative attack; however, the former pathway appears to be of no physiological significance since it generates 2-tetrahydrofuranacetic acid as a nonmetabolizable intermediate, making w-oxidation via adipate the exclusive pathway for degradation.

5-Hydroxyhexanoic acid
5-Hydroxyhexanoic acid is a normal dicarboxylic acid degradation product of fatty acids; however, it has been found in patients with non-ketotic dicarboxylic aciduria and one patient on a diet containing excessive amounts of medium-chain triglycerides. Increased amounts of dicarboxylic acids are excreted in human urine under conditions of medium-chain triglyceride (MCT) feeding, abnormal fatty acid oxidation (FAO) and fasting. Criteria to distinguish dicarboxylic aciduria originating from MCT feeding and other conditions are needed in urinary organic acid profiling for detecting inborn errors of metabolism. Medium-chain triglycerides (MCTs) are absorbed and metabolized differently from long-chain triglycerides (LCTs). MCTs may be useful as a dietary substitute in a variety of clinical disorders. Urinary excretion of 5-hydroxyhexanoic acid, the (omega-1) hydroxylation product, was increased during MCT feeding as compared with LCT feeding in patients with non-insulin-dependent diabetes mellitus (PMID: 6897376, 2239769, 8596483). Moreover, 5-hydroxyhexanoic acid is also found to be associated with Medium chain acyl-CoA dehydrogenase deficiency (MCADD), which is also an inborn error of metabolism. 5-Hydroxyhexanoic acid has be found to be a microbial metabolite (PMID: 20615997). 5-Hydroxyhexanoic acid is a normal dicarboxylic acid degradation product of fatty acids; however, it has been found in patients with non-ketotic dicarboxylic aciduria and one patient on a diet containing excessive amounts of medium-chain triglycerides.

Leucinic acid
Leucinic acid, also known as leucic acid, 2-hydroxyisocaproic acid or 2-hydroxy-4-methylvaleric acid, belongs to the class of organic compounds known as hydroxy fatty acids. These are fatty acids in which the chain bears a hydroxyl group. Leucinic acid is a valeric acid derivative having a hydroxy substituent at the 2-position and a methyl substituent at the 4-position. It is an alpha-hydroxy analogue of leucine and a metabolite of the branched-chain amino acid leucine. Leucinic acid is found in all organisms ranging from bacteria to plants to animals. Leucinic acid has been found in a patient with dihydrolipoyl dehydrogenase (DLD) deficiency (PMID: 6688766). DLD deficiency is caused by mutations in the DLD gene and is inherited in an autosomal recessive manner. A common feature of dihydrolipoamide dehydrogenase deficiency is a potentially life-threatening buildup of lactic acid in tissues (lactic acidosis), which can cause nausea, vomiting, severe breathing problems, and an abnormal heartbeat. Neurological problems are also common in this condition; the first symptoms in affected infants are often decreased muscle tone (hypotonia) and extreme tiredness (lethargy). As the problems worsen, affected infants can have difficulty feeding, decreased alertness, and seizures. Liver problems can also occur in dihydrolipoamide dehydrogenase deficiency, ranging from an enlarged liver (hepatomegaly) to life-threatening liver failure. In some affected people, liver disease, which can begin anytime from infancy to adulthood, is the primary symptom. Leucinic acid is also present in the urine of patients with short bowel syndrome (PMID: 4018104) Leucinic acid has been isolated from amniotic fluid (PMID: 6467607), and have been found in a patient with dihydrolipoyl dehydrogenase deficiency (PMID 6688766).
Hydroxyisocaproic acid
Hydroxyisocaproic acid is an end product of leucine metabolism in human tissues such as muscle and connective tissue. It belongs to 2-hydroxycarboxylic acid group of amino acid metabolites (PMID 6434570). Hydroxyisocaproic acid functions as an “anti-catabolite” and is widely used in the body building community. Chronic alpha-hydroxyisocaproic acid treatment of rats has been shown to improve muscle recovery after immobilization-induced atrophy (PMID: 23757407). Additionally, a 4-week hydroxyisocaproic acid supplementation of 1.5 g a day was shown to lead to increases in muscle mass during an intensive training period among soccer athletes (PMID: 20051111). Hydroxyisocaproic acid has also shown some potential as a topical antibiotic (PMID: 22483561). Elevated levels of 2-hydroxyisocaproic acid have been found in the urine of patients with dihydrolipoyl dehydrogenase (E3) deficiency (PMID: 6688766). Hydroxyisocaproic acid is also elevated in maple syrup urine disease, a genetic disorder, and has been shown to accelerate lipid peroxidation. It may also be an indicator of oxidative stress (PMID: 11894849). Hydroxyisocaproic acid has been found to be a metabolite of Lactobacillus and fungal species (http://jultika.oulu.fi/files/isbn9789526211046.pdf).

The (R)-enantiomer of 2-hydroxy-4-methylpentanoic acid. Found in patients with short-bowel syndrome (an inborn error of metabolism), and in maple syrup urine disease, MSUD. (R)-Leucic acid is an amino acid metabolite[1].
(2R,4S)-2,4-diaminopentanoic acid
The (2R,4S)-diastereomer of 2,4-diaminopentanoic acid
(S)-2-hydroxy-4-methylpentanoic acid
The (S)-enantiomer of 2-hydroxy-4-methylpentanoic acid. Derived from the metabolism of the branched-chain amino acids, it belongs to the 2-hydroxycarboxylic acid group of amino acid metabolites.
DL-Leucic Acid
A valeric acid derivative having a hydroxy substituent at the 2-position and a methyl substituent at the 4-position; an alpha-hydroxy analogue of leucine. A bacterial metabolite, it has also been isolated from amniotic fluid, was found in a patient with dihydrolipoyl dehydrogenase deficiency and is present in the urine of patients with short bowel syndrome.
5-Hydroxyhexanoic acid
A medium-chain fatty acid that is hexanoic acid substituted at position 5 by a hydroxy group.
(2R,3S)-2-hydroxy-3-methylpentanoic acid
A valeric acid derivative having an (R)-hydroxy substituent at the 2-position and an (S)-methyl substituent at the 3-position; one of 4 steroisomers of 2-hydroxy-3-methylpentanoic acid, generated by isoleucine metabolism. Found at significantly higher levels than normal in patients with maple syrup urine disease (MSUD).
4-ETHENYL-1,2-DIMETHYLBENZENE
A member of the class of styrenes that is 1,2-dimethylbenzene substituted by a vinyl group at position 4.
3-hydroxy-2,2-dimethylbutyric acid
A 3-hydroxy monocarboxylic acid that is 2,2-dimethylbutyric acid carrying a single hydroxy substituent at position 3.
(2S,3R)-3-hydroxy-2-methylpentanoic acid
A diketide with a pentanoic acid structure substituted at the alpha and beta positions by methyl and hydroxy groups respectively.
2,4-diaminopentanoic acid
A diamino acid consisting of pentanoic acid having the amino substituents placed in the 2- and 4-positions.
