N-Acetylleucine
N-Acetyl-L-leucine or N-Acetylleucine, belongs to the class of organic compounds known as N-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. N-Acetylleucine can also be classified as an alpha amino acid or a derivatized alpha amino acid. Technically, N-Acetylleucine is a biologically available N-terminal capped form of the proteinogenic alpha amino acid L-lecuine. N-acetyl amino acids can be produced either via direct synthesis of specific N-acetyltransferases or via the proteolytic degradation of N-acetylated proteins by specific hydrolases. N-terminal acetylation of proteins is a widespread and highly conserved process in eukaryotes that is involved in protection and stability of proteins (PMID: 16465618). About 85\\\\% of all human proteins and 68\\\\% of all yeast proteins are acetylated at their N-terminus (PMID: 21750686). Several proteins from prokaryotes and archaea are also modified by N-terminal acetylation. The majority of eukaryotic N-terminal-acetylation reactions occur through N-acetyltransferase enzymes or NAT’s (PMID: 30054468). These enzymes consist of three main oligomeric complexes NatA, NatB, and NatC, which are composed of at least a unique catalytic subunit and one unique ribosomal anchor. The substrate specificities of different NAT enzymes are mainly determined by the identities of the first two N-terminal residues of the target protein. The human NatA complex co-translationally acetylates N-termini that bear a small amino acid (A, S, T, C, and occasionally V and G) (PMID: 30054468). NatA also exists in a monomeric state and can post-translationally acetylate acidic N-termini residues (D-, E-). NatB and NatC acetylate N-terminal methionine with further specificity determined by the identity of the second amino acid. N-acetylated amino acids, such as N-acetylleucine can be released by an N-acylpeptide hydrolase from peptides generated by proteolytic degradation (PMID: 16465618). In addition to the NAT enzymes and protein-based acetylation, N-acetylation of free leucine can also occur. In particular, N-Acetylleucine can be biosynthesized from L-leucine and acetyl-CoA by the enzyme leucine N-acetyltransferase (EC 2.3.1.66). Excessive amounts N-acetyl amino acids including N-acetylleucine (as well as N-acetylglycine, N-acetylserine, N-acetylglutamine, N-acetylglutamate, N-acetylalanine, N-acetylmethionine and smaller amounts of N-acetylthreonine, N-acetylisoleucine, and N-acetylvaline) can be detected in the urine with individuals with acylase I deficiency, a genetic disorder (PMID: 16465618). Aminoacylase I is a soluble homodimeric zinc binding enzyme that catalyzes the formation of free aliphatic amino acids from N-acetylated precursors. In humans, Aminoacylase I is encoded by the aminoacylase 1 gene (ACY1) on chromosome 3p21 that consists of 15 exons (OMIM 609924). Individuals with aminoacylase I deficiency will experience convulsions, hearing loss and difficulty feeding (PMID: 16465618). ACY1 can also catalyze the reverse reaction, the synthesis of acetylated amino acids. Many N-acetylamino acids, including N-acetylleucine are classified as uremic toxins if present in high abundance in the serum or plasma (PMID: 26317986; PMID: 20613759). Uremic toxins are a diverse group of endogenously produced molecules that, if not properly cleared or eliminated by the kidneys, can cause kidney damage, cardiovascular disease and neurological deficits (PMID: 18287557).

2-Oxoarginine
2-Oxoarginine is a guanidino compound metabolite of arginine catabolism. 2-Oxoarginine levels are increased in patients with argininemia (OMIM:207800). Argininemia, characterized by arginase deficiency (EC 3.5.3.1, catalyzes the last step of the urea cycle) is an autosomal recessive inborn error of metabolism caused by a defect in the final step in the urea cycle, the hydrolysis of arginine to urea and ornithine. Accumulation of arginine metabolites (such as guanidino compounds) especially 2-oxoarginine, may produce the central nervous system damage in argininemia. (PMID: 3433275 , 1588833 , 1690873 , 819629). 2-Oxoarginine has also been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821). 2-Oxoarginine is a guanidino compound metabolite of arginine catabolism. 2-Oxoarginine levels are increased in patients with argininemia (OMIM:207800).

Hexanoylglycine
Hexanoylglycine is an acyl glycine. Acyl glycines are normally minor metabolites of fatty acids. However, the excretion of certain acyl glycines is increased in several inborn errors of metabolism. In certain cases the measurement of these metabolites in body fluids can be used to diagnose disorders associated with mitochondrial fatty acid beta-oxidation. Acyl glycines are produced through the action of glycine N-acyltransferase (EC 2.3.1.13) which is an enzyme that catalyzes the chemical reaction: acyl-CoA + glycine < -- > CoA + N-acylglycineHexanoylglycine is a fatty acid metabolite, it appears in the urine of patients with hereditary medium-chain acyl-CoA dehydrogenase (MCAD) deficiency (PMID 2775902), which is a genetic disorder.

Isovalerylalanine
Isovalerylalanine, also known as isopentanoylalanine, belongs to the class of organic compounds known as N-acyl-L-alpha-amino acids. These are N-acylated alpha amino acids which have the L-configuration of the alpha-carbon atom. Isovalerylalanine results from the formal condensation of the carboxy group of isovaleric acid with the amino group of L-alanine. Isovalerylalanine is one of the constituents of the organic acid profile in isovaleric acidemia, it is believed to be formed by the action of the enzyme glycine N-acylase on alanine, using isovaleryl-CoA as a substrate (PMID: 6197208). Isovaleric acidemia was the first organic acid acidemia to be documented in humans. It is an autosomal recessive inborn error in the metabolism of leucine, caused by a deficiency of the mitochondrial enzyme isovaleryl-CoA dehydrogenase (IVD) that results in the accumulation isovaleryl-CoA derivatives (PMID: 16602101). The excess of isovaleryl-CoA in plasma allows for the formation of condensation derivatives, such as isovalerylalanine which makes it one of the biomarkers for this condition. Isovalerylalanine is a metabolite

N-isovalerylsarcosine is a minor but characteristic constituent of the organic acid profile in isovaleric acidemia.
