2,4-Dihydroxy-2H-1,4-benzoxazin-3(4H)-one
2,4-Dihydroxy-2H-1,4-benzoxazin-3(4H)-one is a benzoxazinoid precursor of 2-aminophenol sulfate. It is a metabolite found in urine of individuals that have consumed whole grains. It is a particularly strong biomarker for whole grain rye bread consumption (PMID: 23307617). Isolated from seedlings of rye and sweet corn (Zea mays). 2,4-Dihydroxy-2H-1,4-benzoxazin-3(4H)-one is found in cereals and cereal products and fats and oils.

Acamprosate
Acamprosate, also known by the brand name Campral™, is a drug used for treating alcohol dependence. Acamprosate is thought to stabilize the chemical balance in the brain that would otherwise be disrupted by alcoholism, possibly by blocking glutaminergic N-methyl-D-aspartate receptors, while gamma-aminobutyric acid type A receptors are activated. Reports indicate that acamprosate only works with a combination of attending support groups and abstinence from alcohol. Certain serious side effects include allergic reactions, irregular heartbeats, and low or high blood pressure, while less serious side effects include headaches, insomnia, and impotence. Acamprosate should not be taken by people with kidney problems or allergies to the drug.

Methionine sulfone
S-dioxymethionine, also known as (S)-amino-4-(methylsulphonyl)butyric acid or methionine sulfone, is a member of the class of compounds known as L-alpha-amino acids. L-alpha-amino acids are alpha amino acids which have the L-configuration of the alpha-carbon atom. S-dioxymethionine is soluble (in water) and a moderately acidic compound (based on its pKa). S-dioxymethionine can be found in garden onion, which makes S-dioxymethionine a potential biomarker for the consumption of this food product. Methionine sulfone (CAS: 820-10-0), also known as L-methionine-S-dioxide, belongs to the class of organic compounds known as L-alpha-amino acids. These are alpha-amino acids which have the L-configuration at the alpha-carbon atom. Methionine sulfone is a very strong basic compound (based on its pKa). Methionine sulfone has been detected, but not quantified, in garden onions. This could make methionine sulfone a potential biomarker for the consumption of these foods.
(R+)-3-(4-hydroxyphenyl)lactate
(r+)-3-(4-hydroxyphenyl)lactate, also known as (2r)-2-hydroxy-3-(4-hydroxyphenyl)propanoate or P-hydroxyphenyllactic acid, is a member of the class of compounds known as phenylpropanoic acids. Phenylpropanoic acids are compounds with a structure containing a benzene ring conjugated to a propanoic acid (r+)-3-(4-hydroxyphenyl)lactate is soluble (in water) and a weakly acidic compound (based on its pKa). (r+)-3-(4-hydroxyphenyl)lactate can be found in a number of food items such as muskmelon, coconut, lemon grass, and kohlrabi, which makes (r+)-3-(4-hydroxyphenyl)lactate a potential biomarker for the consumption of these food products.
