Heptanal is an aldehydic, citrus, and fat tasting compound. heptanal is found, on average, in the highest concentration in a few different foods, such as corns, tea, and sweet oranges and in a lower concentration in lemons, wild carrots, and carrots. heptanal has also been detected, but not quantified, in several different foods, such as horned melons, common beets, dills, red bell peppers, and malus (crab apple). 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).

Hexanal

N-Caproic aldehyde

C6H12O (100.0888)


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.

2-octenal, also known as 2-octenal, (Z)-isomer, 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-octenal is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 2-octenal has a fatty and green taste. 2-octenal can be found primarily in blood. 2-octenal is a non-carcinogenic (not listed by IARC) potentially toxic compound. As a uremic toxin, this compound can cause uremic syndrome. Uremic syndrome may affect any part of the body and can cause nausea, vomiting, loss of appetite, and weight loss. It can also cause changes in mental status, such as confusion, reduced awareness, agitation, psychosis, seizures, and coma. Abnormal bleeding, such as bleeding spontaneously or profusely from a very minor injury can also occur. Heart problems, such as an irregular heartbeat, inflammation in the sac that surrounds the heart (pericarditis), and increased pressure on the heart can be seen in patients with uremic syndrome. Shortness of breath from fluid buildup in the space between the lungs and the chest wall (pleural effusion) can also be present (T3DB).
