Homovanillic acid sulfate
Homovanillic acid sulfate is a component of olive oil and is a major catecholamine metabolite. It is used as a reagent to detect oxidative enzymes and is associated with dopamine levels in the brain. In psychiatry and neuroscience, brain and cerebrospinal fluid levels of homovanillic acid (HVA) are measured as a marker of metabolic stress caused by 2-deoxy-D-glucose. HVA presence supports a diagnosis of neuroblastoma and malignant pheochromocytoma (Wikipedia). Homovanillic acid sulfate is an endogenous phenolic acid metabolite detected after the consumption of whole grain. Homovanillic acid sulfate is a component of olive oil and is a major catecholamine metabolite.It is used as a reagent to detect oxidative enzymes, and is associated with dopamine levels in the brain.

3-hydroxy-3-(3-hydroxyphenyl)propanoic acid-O-sulphate
3-hydroxy-3-(3-hydroxyphenyl)propanoic acid-O-sulphate is the conjugate of 3-hydroxy-3-(3-hydroxyphenyl)propanoic acid and sulphate. (3-Hydroxyphenyl)hydracrylate (HPHPA) is an organic acid detected in human urine. It is thought that the presence of this acid is from nutritional sources (i.e. dietary phenylalanine). However, there has been a considerable degree of ambiguity in the origin and/or significance of this compound (PMID:11978597). Recently it has been reported that HPHPA is actually an abnormal phenylalanine metabolite arising from bacterial metabolism in the gastrointestinal tract. Specifically HPHPA appears to arise from the action of the anaerobic bacteria Clostrida sp. (PMID:20423563). Elevated levels of HPHPA have been reported in the urine of children with autism as well as in adult patients with schizophrenia. It has been proposed that HPHPA may be a bacterial metabolite of m-tyrosine, a tyrosine analog that causes symptoms of autism in experimental animals.
3-(3,5-dihydroxyphenyl)-1-propanoic acid sulphate
3-(3,5-dihydroxyphenyl)-1-propanoic acid sulphate 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).

Arctinone A
Arctinone a is a member of the class of compounds known as bi- and oligothiophenes. Bi- and oligothiophenes are organic compounds containing two or more linked thiophene rings. Thiophene is a five-member aromatic ring with one sulfur and four carbon atoms. Arctinone a is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Arctinone a can be found in burdock, which makes arctinone a a potential biomarker for the consumption of this food product.
