Propynoic acid
Propynoic acid, also known as propiolic acid, is involved in propanoate metabolism and is interconverted into 2-propyn-1-al by mitochondrial aldehyde dehydrogenase. Propynoic acid is an unsaturated organic acid and it can be prepared by boiling acetylene dicarboxylic acid. It is chemically obtained by the action of alcoholic potash on dibromosuccinic acid, or its acid potassium salt with water. It forms silky crystals which melt at 6°C and boil at about 144°C with decomposition. It is soluble in water and possesses an odour resembling that of acetic acid. Exposure to sunlight converts it into trimesic acid (benzene-1,3,5-tricarboxylic acid). It undergoes bromination to give dibromoacrylic acid. With hydrogen chloride it forms chloroacrylic acid. Its ethyl ester condenses with hydrazine to form pyrazolone. Propynoic acid forms a characteristic explosive silver salt upon the addition of ammoniacal silver nitrate to its aqueous solution, and an amorphous precipitate which explodes upon warming with ammoniacal cuprous chloride. Its ethyl ester condenses with hydrazine to form pyrazolone (Wikipedia). Propynoic acid is involved in propanoate metabolism and is interconverted between 2-propyn1-al and propynoic acid by mitochondrial aldehyde dehydrogenase. Propiolic acid is an unsaturated organic acid and it can be prepared by boiling acetylene dicarboxylic acid. It is chemically obtained by the action of alcoholic potash on dibromosuccinic acid, or its acid potassium salt with water. It forms silky crystals which melt at 6 degree centigrade, and boil at about 144 degree centigrade with decomposition. It is soluble in water and possesses an odor resembling that of acetic acid. Exposure to sunlight converts it into trimesic acid (benzene-1,3,5-tricarboxylic acid). Bromine converts it into dibromoacrylic acid, and it gives with hydrochloric acid O-chloracrylic acid. It forms a characteristic explosive silver salt on the addition of ammoniacal silver nitrate to its aqueous solution, and an amorphous precipitate which explodes on warming with ammoniacal cuprous chloride. Its ethyl ester condenses with hydrazine to form pyrazolone. [HMDB] KEIO_ID P040
2-Butenal
(e)-2-butenal, also known as (cis)-crotonaldehyde or (E)-crotonaldehyde (iupac), is a member of the class of compounds known as enals. Enals are an alpha,beta-unsaturated aldehyde of 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 (e)-2-butenal is soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). (e)-2-butenal is a flower tasting compound found in fruits, garden tomato, and potato, which makes (e)-2-butenal a potential biomarker for the consumption of these food products (e)-2-butenal can be found primarily in feces and saliva. 2-Butenal (CAS: 4170-30-3), also known as crotonaldehyde, 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. The (E)-form of 2-butenal predominates (>95\\%). 2-Butenal can undergo polycondensation with phenols to synthesize phenolic resins. It is an eye, skin, and mucous membrane irritant. (E)-2-Butenal is found in fruits and vegetables (e.g. tomato juice, strawberry aroma).

3-Buten-2-one
But-3-en-2-one, also known as 2-butenone or methyl vinyl ketone, is a member of the class of compounds known as enones. Enones are compounds containing the enone functional group, with the structure RC(=O)CR. Thus, but-3-en-2-one is considered to be an oxygenated hydrocarbon lipid molecule. But-3-en-2-one is soluble (in water) and an extremely weak acidic compound (based on its pKa). But-3-en-2-one can be found in a number of food items such as kai-lan, roman camomile, black chokeberry, and orange mint, which makes but-3-en-2-one a potential biomarker for the consumption of these food products. But-3-en-2-one can be found primarily in saliva. 3-Buten-2-one, also called methyl vinyl ketone, is the organic compound with the formula CH3CCH=CH2. It is a reactive compound classified as an enone, in fact the simplest example thereof. It is a colorless, flammable, highly toxic liquid with a pungent odor. It is soluble in water and polar organic solvents. It is a useful intermediate in the synthesis of other compounds.
Methacrolein
Methacrolein, or methacrylaldehyde, is an unsaturated aldehyde. It is a clear, colorless, flammable liquid that is present in cigarettes when smoking.

2,3-DHF
Dihydrofuran i, also known as 4,5-dihydrofuran, is a member of the class of compounds known as dihydrofurans. Dihydrofurans are compounds containing a dihydrofuran moiety, which is a furan derivative with only one double bond. Dihydrofuran i is soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Dihydrofuran i can be found in common grape, which makes dihydrofuran i a potential biomarker for the consumption of this food product.
