2,3-Diaminopropionic acid
2,3-Diaminopropionic acid, also known as L-2,3-diaminopropanoate or Dpr, belongs to the class of organic compounds known as l-alpha-amino acids. These are alpha amino acids which have the L-configuration of the alpha-carbon atom. 2,3-Diaminopropionic acid is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. 2,3-Diaminopropionic acid (2,3-diaminopropionate) is a non-proteinogenic amino acid found in certain secondary metabolites, including zwittermicin A and tuberactinomycin.2,3-Diaminopropionate is formed by the pyridoxal phosphate (PLP) mediated amination of serine. 2,3-Diaminopropionic acid exists in all living organisms, ranging from bacteria to humans. 2,3-Diaminopropionic acid is a metabolite of b-oxalyl-L-a,b-diaminopropionic acid a neurotoxic amino acid (ODAP).

Styrene
Styrene, also known as vinylbenzene or phenylethylene, belongs to the class of organic compounds known as styrenes. These are organic compounds containing an ethenylbenzene moiety. The metabolites of styrene are excreted mainly in the urine. Styrene is possibly neutral. Styrene is a sweet, balsamic, and floral tasting compound. Styrene has been detected, but not quantified, in several different foods, such as coffee and coffee products, fruits, cocoa and cocoa products, alcoholic beverages, and chinese cinnamons. This could make styrene a potential biomarker for the consumption of these foods. A minor pathway of styrene metabolism involves the formation of phenylacetaldehyde from styrene 7,8-oxide or cytochrome P450 conversion of styrene to pheylethanol and subsequent metabolism to phenylacetic acid. Styrene is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. Styrene oxide is predominantly metabolized by epoxide hydrolase to form styrene glycol; the styrene glycol is subsequently converted to mandelic acid, phenylglyoxylic acid, and hippuric acid. Styrene, with regard to humans, has been found to be associated with several diseases such as nonalcoholic fatty liver disease and ulcerative colitis; styrene has also been linked to the inborn metabolic disorder celiac disease. Styrene may be absorbed following ingestion, inhalation, or dermal exposure. Breathing high levels of styrene may cause nervous system effects such as changes in color vision, tiredness, feeling drunk, slowed reaction time, concentration problems, or balance problems. Chest burning, wheezing, and dyspnea may also occur. Styrene causes nervous system depression and may be carcinogenic. Present in cranberry, bilberry, currants, grapes, vinegar, parsley, milk and dairy products, whisky, cocoa, coffee, tea, roasted filberts and peanuts. Flavouring ingredient. Polymers are used in ion-exchange resins in food processing. Indirect food additive arising from adhesives, oatings and packaging materials

(±)-2-Pentanethiol
(s)-2-pentanethiol is a member of the class of compounds known as alkylthiols. Alkylthiols are organic compounds containing the thiol functional group linked to an alkyl chain (s)-2-pentanethiol is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). (s)-2-pentanethiol can be found in fruits, which makes (s)-2-pentanethiol a potential biomarker for the consumption of this food product. (S)-2-Pentanethiol is found in fruits. (S)-2-Pentanethiol is a component of guava flavour (Psidium guajava).
Ethyl isopropyl sulfide
Ethyl isopropyl sulfide is a member of the class of compounds known as dialkylthioethers. Dialkylthioethers are organosulfur compounds containing a thioether group that is substituted by two alkyl groups. Ethyl isopropyl sulfide can be found in ginger, which makes ethyl isopropyl sulfide a potential biomarker for the consumption of this food product.
