5,6-dihydrouracil
Dihydrouracil 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. Dihydrouracil is an intermediate breakdown product of uracil. Dihydrouracil exists in all living organisms, ranging from bacteria to plants to humans. Within humans, dihydrouracil participates in a number of enzymatic reactions. In particular, dihydrouracil can be biosynthesized from uracil; which is mediated by the enzyme dihydropyrimidine dehydrogenase [NADP(+)]. The breakdown of uracil is a multistep reaction that leads to the production of beta-alanine. The reaction process begins with the enzyme known as dihydropyrimidine dehydrogenase (DHP), which catalyzes the reduction of uracil into dihydrouracil. Then the enzyme known as dihydropyrimidinase hydrolyzes dihydrouracil into N-carbamyl-beta-alanine. Finally, beta-ureidopropionase catalyzes the conversion of N-carbamyl-beta-alanine into beta-alanine. There is at least one metabolic disorder that is associated with altered levels of dihydrouracil. In particular, dihydropyrimidinase deficiency is an inborn metabolic disorder that leads to highly increased concentrations of dihydrouracil and 5,6-dihydrothymine, and moderately increased concentrations of uracil and thymine in urine. Dihydropyrimidinase deficiency can cause neurological and gastrointestinal problems in some affected individuals (OMIM: 222748). In particular, patients with dihydropyrimidinase deficiency exhibit a number of neurological abnormalities including intellectual disability, seizures, weak muscle tone (hypotonia), an abnormally small head size (microcephaly), and autistic behaviours that affect communication and social interaction. Gastrointestinal problems that occur in dihydropyrimidinase deficiency include backflow of acidic stomach contents into the esophagus (gastroesophageal reflux) and recurrent episodes of vomiting. 3,4-dihydrouracil, also known as 2,4-dioxotetrahydropyrimidine or 5,6-dihydro-2,4-dihydroxypyrimidine, is a member of the class of compounds known as pyrimidones.

In humans, 3,4-dihydrouracil is involved in a couple of metabolic pathways, which include beta-alanine metabolism and pyrimidine metabolism. 3,4-dihydrouracil is also involved in several metabolic disorders, some of which include UMP synthase deficiency (orotic aciduria), dihydropyrimidinase deficiency, ureidopropionase deficiency, and carnosinuria, carnosinemia. Moreover, 3,4-dihydrouracil is found to be associated with dihydropyrimidine dehydrogenase deficiency and hypertension.

delta-Hexanolactone
delta-Hexanolactone is the lactone of 5-hydroxyhexanoic acid. Lactones are internal esters that exist in equilibrium between their closed (lactone) and open (hydroxy acid) forms in an aqueous environment. The lactone/hydroxy acid ratio at equilibrium is pH-dependent, with the closed form being favored at lower pH values, and can be greatly influenced by structural features of the lactone such as the ring size, substituents on the ring and the presence of double bonds within the ring. Many drugs and endogenous compounds are lactones or hydroxy acids and an enzyme capable of catalyzing the interchange between the open and closed forms in vivo could have pronounced effects upon their biological activity and/or distribution. delta-Hexanolactone is the substrate of paraoxonases (PON) in humans. Human PON1 hydrolyzes over 30 different lactones (cyclic esters) and catalyzes the reverse reaction (lactonization) of a broad range of hydroxy acids.

Gamma-Caprolactone
Gamma-Caprolactone, also known as 4-ethyl-4-butanolide or 4-hexanolide, belongs to the class of organic compounds known as gamma butyrolactones. Gamma butyrolactones are compounds containing a gamma butyrolactone moiety, which consists of an aliphatic five-member ring with four carbon atoms, one oxygen atom, and bears a ketone group on the carbon adjacent to the oxygen atom. Thus, Gamma-caprolactone is considered to be a fatty ester lipid molecule. Gamma-Caprolactone is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Gamma-Caprolactone exists in all eukaryotes, ranging from yeast to humans. Outside of the human body, Gamma-caprolactone has been detected, but not quantified in several different foods, such as potato, cereals and cereal products, pomes, alcoholic beverages, and fruits. It is occasionally found as a volatile component of human urine. In some cases differences up to an order of magnitude are observed. It has been also found in the polar fraction of human blood. Constituent of fruits, e.g. apple, raspberry, strawberry, wine grapes, quince etcand is) also present in French fried potato, wheat bread, crispbread, butter, red or white wine and cooked beef. xi-5-Ethyldihydro-2(3H)-furanone is found in many foods, some of which are animal foods, fruits, pomes, and potato. γ-Hexalactone is a gamma-lactone found in ripe fruits. γ-Hexalactone induces DNA damage and acts a substrate of paraoxonase 1 (PON1)[1][2][3]. γ-Hexalactone is a gamma-lactone found in ripe fruits. γ-Hexalactone induces DNA damage and acts a substrate of paraoxonase 1 (PON1)[1][2][3].
