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.

This could make heptanal a potential biomarker for the consumption of these foods. The formation of heptanal in the fractional distillation of castor oil was already described in 1878. The large-scale production is based on the pyrolytic cleavage of ricinoleic acid ester (Arkema method) and on the hydroformylation of 1-hexene with rhodium 2-ethylhexanoate as a catalyst upon addition of some 2-ethylhexanoic acid (Oxea method):Heptanal naturally occurs in the essential oils of ylang-ylang (Cananga odorata), clary sage (Salvia sclarea), lemon (Citrus x limon), bitter orange (Citrus x aurantium), rose (Rosa) and hyacinth (Hyacinthus).

C6H12O (100.0888102)


Hexanal is an alkyl aldehyde found in human biofluids. Human milk samples collected from women contains hexanal. Among mediators of oxidative stress, highly reactive secondary aldehydic lipid peroxidation products can initiate the processes of spontaneous mutagenesis and carcinogenesis and can also act as a growth-regulating factors and signaling molecules. In specimens obtained from adult patients with brain astrocytomas, lower levels of n-hexanal are associated with poorer patient prognosis. Hexanal has also been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID:22626821). Hexanal is a volatile compound that has been associated with the development of undesirable flavours. The content of hexanal, which is a major breakdown product of linoleic acid (LA, n - 6 PUFA) oxidation, has been used to follow the course of lipid oxidation and off-flavour development in foods, and have been proposed as one potential marker of milk quality. A "cardboard-like" off-flavour is frequently associated with dehydrated milk products. This effect is highly correlated with the headspace concentration of hexanal. (Food Chemistry. Volume 107, Issue 1, 1 March 2008, Pages 558-569, PMID:17934948, 17487452). Constituent of many foodstuffs. A production of aerobic enzymatic transformations of plant constits.

Cilantro is a delightful spice added to make tacos and guacamole delicious and enliven the taste and aroma of many Spanish/Mexican foods. However for some people cilantro tastes and smells like soap. A number of famous chefs abhor(ed) cilantro, including Julia Child, Ina Garten (aka Barefoot Contessa) and Top Chef Fabio Viviani. It turns out that the compound that gives Cilantro the pleasant citrus taste/smell is 2-dodecenal. If you have a mutation in an olafactory receptor, it cant distinguish between 2-dodecenal and 1-dodecenal. 1-dodecenal tastes and smells soapy.

2,4-Heptadienal or (E,E)-2,4-heptadienal belongs to the class of organic compounds known as medium-chain aldehydes. These are an aldehyde with a chain length containing between 6 and 12 carbon atoms. Thus, 2,4-heptadienal is considered to be a fatty aldehyde. 2,4-heptadienal is also known as polyunsaturated aldehyde. These compounds are classified by an aldehyde group covalently bound to long carbon chains containing two or more carbon-carbon double bonds. 2,4-heptadienal is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. 2,4-heptadienal is an aldehydic, cake, and cinnamon tasting compound. 2,4-heptadienal has been detected, but not quantified in, several different foods, such as evergreen blackberries, cabbages, broccoli, corns, and tortilla chips. This could make 2,4-heptadienal a potential biomarker for the consumption of these foods. 2,4-heptadienal is also used as a flavoring additive in cigarettes.
