5-Hydroxymethyluracil
5-Hydroxymethyluracil (5hmU), also known as alpha-hydroxythymine, belongs to the class of organic compounds known as pyrimidones. Pyrimidones are compounds that contain a pyrimidine ring, which bears a ketone. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. 5hmU has been identified as a thymine base modification found in the genomes of a diverse range of organisms (PMID: 28137275). 5-hydroxymethyluracil has been detected in bacteriophages, dinoflagellates, leishmania, and in eukaryotic genomes where its level appears to be cell type-specific. 5-Hydroxymethyluracil arises from the oxidation of thymine. 5-Hydroxymethyluracil is produced by the enzyme thymine dioxygenase (EC 1.14.11.6) which catalyzes the chemical reaction thymine + 2-oxoglutarate + O2 <-> 5-hydroxymethyluracil + succinate + CO2. The 3 substrates of this enzyme are thymine, 2-oxoglutarate, and O2, whereas its 3 products are 5-hydroxymethyluracil, succinate, and CO2. The 5hmU base can also be generated by oxidation/hydroxylation of thymine by the Ten-Eleven-Translocation (TET) proteins or result from deamination of 5hmC (PMID: 29184924). DNA containing 5hmU has been reported to be more flexible and hydrophilic (PMID: 29184924). 5-Hydroxymethyluracil is an oxidation damage product derived from thymine or 5-methylcytosine. It is a product of thymine dioxygenase [EC 1.14.11.6].

cis,cis-Muconic acid
cis-cis-Muconic acid is a presumptive metabolite of benzene. Muconic acid was first isolated from the urine of rabbits and dogs in 1909 (M. Jaffe, Z Physiol Chem 62:58-67). It was originally thought that if muconic acid was formed by the opening of the benzene ring in vivo then the cis-cis isomer should be the initial (and primary) product. However subsequent studies conducted in the 1950s proved that trans-trans-muconic acid is a true metabolite of benzene in mammals (Parke DV, Williams RT. Biochem J 51:339-348 (1952)). Furthermore, dosing rabbits with phenol or catechol also resulted in the urinary excretion of trans-trans-muconic acid. The oxidative ring opening of benzene first gives rise to cis-cis-muconaldehyde, which then isomerizes to cis-trans- and trans-trans-muconaldehyde; the latter is oxidized in vivo to trans-trans-muconic acid. Isomerization of the trans-trans form may take place in vivo to yield small amounts if the cis-cis and cis-trans form of muconic acid. cis-cis-Muconic acid may also be generated from microbial fermentation of benzoic acid. Certain strains of arthobacter are particularly efficient at this process. cis-cis-Muconic acid can also be found in Pseudomonas and Escherichia coli (https://link.springer.com/article/10.1007/BF00250491) (PMID:26360870).

[HMDB] KEIO_ID M105 cis,cis-Muconic acid, a metabolic intermediate of Klebsiella pneumonia, can be converted to adipic acid and terephthalic acid, which are important monomers of synthetic polymers. cis,cis-Muconic acid is also a biochemical material that can be used for the production of various plastics and polymers and is particularly gaining attention as an adipic acid precursor for the synthesis of nylon-6,6[1][2].

2-METHYLNAPHTHALENE
2-methylnaphthalene, also known as 2-methylnaphthalene, lithium salt, ion(1-) or 2-methylnaphthalene, naphthalene-1-(13)c-labeled, is a member of the class of compounds known as naphthalenes. Naphthalenes are compounds containing a naphthalene moiety, which consists of two fused benzene rings. 2-methylnaphthalene can be found in corn, which makes 2-methylnaphthalene a potential biomarker for the consumption of this food product. 2-methylnaphthalene is potentially toxic compound. On February 22, 2014, NASA announced a greatly upgraded database for detecting and monitoring PAHs, including 2-methylnaphthalene, in the universe. According to NASA scientists, over 20\\% of the carbon in the universe may be associated with PAHs, possible starting materials for the formation of life. PAHs seem to have been formed shortly after the Big Bang, are abundant in the universe, and are associated with new stars and exoplanets . Acute exposure to PAHs causes irritation and inflammation of the skin and lung tissue. Some symptoms of hemolytic anemia are fatigue, lack of appetite, restlessness, and pale skin. Exposure to large amounts of 2-methylnapthalene may also cause nausea, vomiting, diarrhea, blood in the urine, and a yellow color to the skin (A10, L12).
Sumiki's acid
Sumikis acid is a naturally occurring human metabolite (PMID:949837). Sumikis acid was first identified in the urine of a leukemic patient who was excreting an abnormal amount of its glycine derivative (PMID:5043270). Sumikis acid was found to be excreted by normal subjects after a phenylalanine loading, while heterozygotes for phenylketonuria dont excrete it (instead, they excrete 2-hydroxybenzeneacetic acid) (PMID:4708049). Patients receiving furan-containing sugar solutions i.v. convert 50\\\\% of the 5-hydroxymethyl-2-furfural into Sumikis acid (PMID:4202014).

Under study conditions, 0.12\\\\% of the sorbic acid dose is excreted in urine as trans,trans-muconic acid thereby indicating that a typical dietary intake of 6-30 mg/day of sorbic acid accounts for 10-50\\\\% of the background of trans,trans-muconic acid excretion in nonsmokers, and for 5-25\\\\% in smokers (PMID: 8021961, 1487326, 9137998, Int Arch Occup Environ Health. 1997;69(4):247-51.). trans,trans-Muconic acid has been found to be a metabolite in Escherichia coli and Pseudomonas putida (PMID: 26360870). cis,cis-Muconic acid, a metabolic intermediate of Klebsiella pneumonia, can be converted to adipic acid and terephthalic acid, which are important monomers of synthetic polymers. cis,cis-Muconic acid is also a biochemical material that can be used for the production of various plastics and polymers and is particularly gaining attention as an adipic acid precursor for the synthesis of nylon-6,6[1][2]. trans-trans-Muconic acid is a urinary metabolite of benzene and has been used as a biomarker of exposure to benzene in human.
