3-Methyl-2-butenal
3-Methyl-2-butenal, also known as senecialdehyde or 3,3-dimethylacrolein, belongs to the class of organic compounds known as enals. These are alpha,beta-unsaturated aldehydes of the general formula RC=C-CH=O in which the aldehydic C=O function is conjugated to a C=C triple bond at the alpha,beta position. 3-methyl-2-butenal has been detected, but not quantified, in several different foods, such as common oregano, beechnuts, oval-leaf huckleberries, tea leaf willows, and red rice. This could make 3-methyl-2-butenal a potential biomarker for the consumption of these foods. 3-Methyl-2-butenal is a derivative of acrolein that is an alpha, beta-unsaturated carbonyl metabolite. It can be formed endogenously during lipid peroxidation or after oxidative stress, and is considered to play an important role in human carcinogenesis. The endogenously formed acroleins are a constant source of DNA damage, can lead to mutation, and can also induce tumours in humans (PMID:8319634). 3-Methyl-2-butenal, which is an unsaturated aldehyde bearing substitution at the alkene terminus, is a poor inactivator of the enzymes protein tyrosine phosphatases (PTPs). The inactivation of PTPs can yield profound biological consequences arising from the disruption of cellular signalling pathways (PMID:17655273). Present in blackberry, grape brandy, cocoa, currants, baked potato, tea, costmary and white bread. Flavouring ingredient
Acrolein
Acrolein (systematic name: propenal) is the simplest unsaturated aldehyde. It is a colourless liquid with a piercing, disagreeable, acrid smell. The smell of burnt fat (i.e. when cooking oil is heated to its smoke point) is caused by glycerol in the burning fat breaking down into acrolein. It is produced industrially from propylene and mainly used as a biocide and a building block to other chemical compounds, such as the amino acid methionine. Acrolein is used as an etherification agent in the preparation of modified food starches. Acrolein is an herbicide and algicide used in water treatment. It is produced by microorganisms, e.g. Clostridium perfringens. Acrolein is a relatively electrophilic compound and a reactive one, hence its high toxicity. It is a good Michael acceptor, hence its useful reaction with thiols. It forms acetals readily, a prominent one being the spirocycle derived from pentaerythritol, diallylidene pentaerythritol. Acrolein participates in many Diels-Alder reactions, even with itself. Via Diels-Alder reactions, it is a precursor to some commercial fragrances, including lyral, norbornene-2-carboxaldehyde, and myrac aldehyde. Acrolein is toxic and is a strong irritant for the skin, eyes, and nasal passages. The main metabolic pathway for acrolein is the alkylation of glutathione. The WHO suggests a tolerable oral acrolein intake of 7.5 µg/day per kilogram of body weight. Although acrolein occurs in French fries, the levels are only a few micrograms per kilogram. Acrolein has also been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID:22626821). Present in fruit aromas, black tea, carrot, cooked potato, cheeses, white wine, hydrolyzed soy protein, turkey, pork, beef fat and other foods. It is used as an etherification agent in the preparation of modified food starches. Herbicide and algicide used in water treatment. Production by microorganisms, e.g. Clostridium perfringens. 2-Propenal is found in many foods, some of which are napa cabbage, sacred lotus, devilfish, and garlic.

Formyl-5-hydroxykynurenamine
Formyl-5-hydroxykynurenamine belongs to the class of organic compounds known as alkyl-phenylketones. These are aromatic compounds containing a ketone substituted by one alkyl group and a phenyl group. Formyl-5-hydroxykynurenamine is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Formyl-5-hydroxykynurenamine can be biosynthesized from serotonin; which is mediated by the enzyme indoleamine 2,3-dioxygenase 1 [EC 1.13.11.52]. In humans, formyl-5-hydroxykynurenamine is involved in the tryptophan metabolism pathway. Formyl-5-hydroxykynurenamine is found in the tryptophan metabolism pathway. It is produced from serotonin through the action of indoleamine 2,3-dioxygenase [EC:1.13.11.52]. [HMDB]
N4-Acetylaminobutanal
N4-Acetylaminobutanal is an intermediate of the urea cycle and metabolism of amino groups, the product of the enzyme monoamine oxidase A [EC:1.4.3.4] and the substrate of the enzyme aldehyde dehydrogenase 2 family (mitochondrial) [EC:1.2.1.3].

3-Butyn-1-al
3-Butyn-1-al is an intermediate in Butanoate metabolism (KEGG ID C06145). It is the third to last step in the synthesis and degradation of ketone bodies and is converted from 3-Butyn-1-ol via the enzyme alcohol dehydrogenase (acceptor) [EC:1.1.99.8]. It is then converted to 3-Butynoate via the enzyme aldehyde dehydrogenase (NAD+) [EC:1.2.1.3]. 3-Butyn-1-al is an intermediate in Butanoate metabolism (KEGG ID
Ethchlorvynol
Ethchlorvynol is only found in individuals that have used or taken this drug. It is a sedative and hypnotic drug. It has been used to treat insomnia, but has been largely superseded and is only offered where an intolerance or allergy to other drugs exists. [Wikipedia]Although the exact mechanism of action is unknown, ethchlorvynol appears to depress the central nervous system in a manner similar to that of barbiturates. Barbiturates bind at a distinct binding sites associated with a Cl- ionopore at the GABAA receptor, increasing the duration of time for which the Cl- ionopore is open. The post-synaptic inhibitory effect of GABA in the thalamus is, therefore, prolonged.
