4-imidazoleacetate
Imidazol-4-ylacetic acid is a monocarboxylic acid that is acetic acid in which one of the methyl hydrogens has been replaced by an imidazol-4-yl group. It has a role as a mouse metabolite. It is a monocarboxylic acid and a member of imidazoles. It derives from an acetic acid. It is a conjugate acid of an imidazol-4-ylacetate. It is a tautomer of an imidazol-5-ylacetic acid and a 2H-imidazol-4-ylacetic acid. Imidazoleacetic acid, also known as 4(5)-imidazoleacetate or IAA, belongs to the class of organic compounds known as imidazolyl carboxylic acids and derivatives. These are organic compounds containing a carboxylic acid chain (of at least 2 carbon atoms) linked to an imidazole ring. Imidazoleacetic acid exists in all living organisms, ranging from bacteria to humans. imidazoleacetic acid can be biosynthesized from imidazole-4-acetaldehyde through its interaction with the enzyme aldehyde dehydrogenase, mitochondrial. In humans, imidazoleacetic acid is involved in histidine metabolism. Outside of the human body, Imidazoleacetic acid has been detected, but not quantified in several different foods, such as chinese cinnamons, jostaberries, vanilla, butternut squash, and red rices. Imidazoleacetic acid is a potentially toxic compound. Imidazoleacetic acid is a metabolite product of Histamine metabolism. Imidazoleacetic acid, also known as 4(5)-imidazoleacetate or imac, belongs to imidazolyl carboxylic acids and derivatives class of compounds. Those are organic compounds containing a carboxylic acid chain (of at least 2 carbon atoms) linked to an imidazole ring. Imidazoleacetic acid is soluble (in water) and a weakly acidic compound (based on its pKa). Imidazoleacetic acid can be found in a number of food items such as grapefruit, garden onion (variety), black crowberry, and yellow zucchini, which makes imidazoleacetic acid a potential biomarker for the consumption of these food products. Imidazoleacetic acid can be found primarily in blood, cerebrospinal fluid (CSF), feces, and urine. In humans, imidazoleacetic acid is involved in the histidine metabolism. Imidazoleacetic acid is also involved in histidinemia, which is a metabolic disorder. 1H-Imidazole-5-acetic acid. CAS Common Chemistry.

Thymine
Thymine, also known as 5-methyluracil, belongs to the class of organic compounds known as hydroxypyrimidines. These are organic compounds containing a hydroxyl group attached to a pyrimidine ring. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. Thymine was first isolated in 1893 by Albrecht Kossel and Albert Neumann from calves thymus glands, hence its name. Thymine is one of the 4 nuelcoebases found in DNA and is essential to all life. Thymine exists in all living species, ranging from bacteria to plants to humans. Thymine combined with deoxyribose creates the nucleoside deoxythymidine (also called thymidine) which when phosphorylated to dTDP can be incorporated into DNA via DNA polymerases. Thymidine can be phosphorylated with up to three phosphoric acid groups, producing dTMP (deoxythymidine monophosphate) dTDP and/or dTTP. In RNA thymine is replaced with uracil in most cases. In DNA, thymine binds to adenine via two hydrogen bonds to assist in stabilizing the nucleic acid structures. Within humans, thymine participates in a number of enzymatic reactions. In particular, thymine and deoxyribose 1-phosphate can be biosynthesized from thymidine through its interaction with the enzyme thymidine phosphorylase. In addition, thymine can be converted into dihydrothymine; which is mediated by the enzyme dihydropyrimidine dehydrogenase [NADP(+)]. One of the pyrimidine bases of living matter.
