(2E)-hexenal is a 2-hexenal in which the olefinic double bond has E configuration. It occurs naturally in a wide range of fruits, vegetables, and spices. It has a role as a flavouring agent, an antibacterial agent and a plant metabolite. 2-Hexenal is a natural product found in Lonicera japonica, Origanum sipyleum, and other organisms with data available. 2-Hexenal is a uremic toxin. Uremic toxins can be subdivided into three major groups based upon their chemical and physical characteristics: 1) small, water-soluble, non-protein-bound compounds, such as urea; 2) small, lipid-soluble and/or protein-bound compounds, such as the phenols and 3) larger so-called middle-molecules, such as beta2-microglobulin. Chronic exposure of uremic toxins can lead to a number of conditions including renal damage, chronic kidney disease and cardiovascular disease. 2-Hexenal is found in allspice. 2-Hexenal is used in perfumery and flavourings. 2-Hexenal belongs to the family of Medium-chain Aldehydes. These are An aldehyde with a chain length containing between 6 and 12 carbon atoms. 2-Hexenal (CAS: 505-57-7), also known as 2-hexenaldehyde or 3-propylacrolein, belongs to the class of organic compounds known as medium-chain aldehydes. These are aldehydes with a chain length containing between 6 and 12 carbon atoms. Thus, 2-hexenal is considered to be a fatty aldehyde lipid molecule. Outside of the human body, 2-hexenal is found, on average, in the highest concentration within a few different foods, such as corn, tea, and bilberries. 2-Hexenal has also been detected, but not quantified in, several different foods, such as common wheat, ginkgo nuts, spearmints, sunflowers, and watermelons. This could make 2-hexenal a potential biomarker for the consumption of these foods. (E)-2-Hexenal is found in allspice. It is used in perfumery and flavouring. (E)-2-Hexenal has also been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821).

Cyclohexanone

Cyclohexanone homopolymer

C6H10O (98.07316100000001)


Cyclohexanone is a food flavourant. Present in various plant spp. e.g. Cistus ladaniferus (labdanum). Cyclohexanone is a colorless oily liquid with an odor resembling acetone and peppermint. Cyclohexanone is occasionally found as a volatile component of human urine. Biological fluids such as blood and urine have been shown to contain a large number of components, some of them volatiles (low boiling point) apparently present in all individuals, while others such are much more variable. In some cases differences up to an order of magnitude are observed. Although some of these changes may have dietary origins, others seem to be characteristic of the individual. Cyclohexanone is obtained through oxidation of cyclohexane or dehydrogenation of phenol. Approx. 95\\% of its manuf. is used for the production of nylon. Information on toxicity to human beings is fragmentary. Acute exposure is characterized by irritation of the eyes, nose, and throat. In two persons, drowsiness and renal impairment were found; Like cyclohexanol, cyclohexanone is not carcinogenic and is only moderately toxic, with a TLV of 25 ppm for the vapor. It is an irritant.; The great majority of cyclohexanone is consumed in the production of precursors to Nylon 66 and Nylon 6. About half of the worlds supply is converted to adipic acid, one of two precursors for nylon 66. For this application, the KA oil (see above) is oxidized with nitric acid. The other half of the cyclohexanone supply is converted to the oxime. In the presence of sulfuric acid catalyst, the oxime rearranges to caprolactam, a precursor to nylon 6:; however, there were embryotoxic effects and influence on reproduction Cyclohexanone is well absorbed through the skin, respiratory tract, and alimentary tract. The main metabolic pathway leads to cyclohexanol, which is excreted in urine coupled with glucuronic acid. A high correlation was found between the concentration of cyclohexanone in the working environment and its concentration in urine. Cyclohexanone is formed from the hydrocarbons cyclohexane and 1-, 2-, and 3-hexanol. A patients case report documents the development of anosmia (an olfactory disorder) and rhinitis caused by occupational exposure to organic solvents, including cyclohexanone (PMID: 10476412, 16925936, 16477465); however, these workers were also exposed to other compounds. Hepatic disorders were found in a group of workers exposed for over five years. In animals, cyclohexanone is characterized by relatively low acute toxicity (DL50 by intragastric administration is approx. 2 g/kg body wt.). Effects on the central nervous system (CNS) were found (narcosis), as well as irritation of the eyes and skin. Following multiple administration, effects were found in the CNS, liver, and kidneys as well as irritation of the conjunctiva. Mutagenic and genotoxic effects were found, but no teratogenic effects were detected Cyclohexanone is a colorless oily liquid with an odor resembling acetone and peppermint.

C6H10O (98.07316100000001)


2-hexenal, also known as hexobarbital, sodium or 3-propyl-acrolein, is a member of the class of compounds known as medium-chain aldehydes. Medium-chain aldehydes are an aldehyde with a chain length containing between 6 and 12 carbon atoms. 2-hexenal is slightly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 2-hexenal is a sweet, almond, and apple tasting compound and can be found in a number of food items such as apple, burdock, pot marjoram, and soy bean, which makes 2-hexenal a potential biomarker for the consumption of these food products. 2-hexenal can be found primarily in blood, feces, and saliva. 2-hexenal is a non-carcinogenic (not listed by IARC) potentially toxic compound.
