A benzaldehyde that is salicylaldehyde which is substituted at position 6 by a (3R,4S,5E)-3,4-dihydroxyhepta-1,5-dien-1-yl group. It is a phytotoxic metabolite, isolated from the rice blast fungi Magnaporthe oryzae and Magnaporthe grisea.
Mycorradicin
Mycorradicin is a member of the class of compounds known as medium-chain fatty acids. Medium-chain fatty acids are fatty acids with an aliphatic tail that contains between 4 and 12 carbon atoms. Mycorradicin is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Mycorradicin can be found in corn, which makes mycorradicin a potential biomarker for the consumption of this food product.
Bromelains
Enzymes occurring in pineapple juice (Ananas sativus); used in tenderising meat and chill-proofing beer [DFC]. Along with papain, bromelain is one of the most popular substances to use for meat tenderizing.; Bromelain can refer to one of two protease enzymes extracted from the plant family Bromeliaceae, or it can refer to a combination of those enzymes along with other compounds produced in an extract. [BioSpider]. Bromelains is found in pineapple and fruits.

6-Hydroxymelatonin
6-Hydroxymelatonin, also known as lopac-H-0627, belongs to the class of organic compounds known as hydroxyindoles. These are organic compounds containing an indole moiety that carries a hydroxyl group. 6-Hydroxymelatonin is considered to be a practically insoluble (in water) and relatively neutral molecule. 6-Hydroxymelatonin has been found in human liver and kidney tissues, and has also been detected in multiple biofluids, such as urine and blood. Within the cell, 6-hydroxymelatonin is primarily located in the cytoplasm. 6-Hydroxymelatonin is the main primary metabolite that can be biosynthesized from melatonin through its interaction with the enzyme cytochrome P450 (CYP) 1A2 (PMID: 11452239). In humans, 6-hydroxymelatonin is involved in the tryptophan metabolism pathway. Melatonin is a hormone that is metabolized by cytochrome P450 (CYP) 1A2 to its main primary metabolite 6-hydroxymelatonin. (PMID 11452239) [HMDB]. 6-Hydroxymelatonin is found in many foods, some of which are garden onion, millet, peppermint, and apricot.

Methionyl-Valine
Methionyl-Valine is a dipeptide composed of methionine and valine. It is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis. This dipeptide has not yet been identified in human tissues or biofluids and so it is classified as an Expected metabolite.
Valylmethionine
Valylmethionine is a dipeptide composed of valine and methionine. It is an incomplete breakdown product of protein digestion or protein catabolism. Dipeptides are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Some dipeptides are known to have physiological or cell-signalling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis.

2-Oxomelatonin is a metabolite of melatonin. Melatonin Listen/ˌmɛləˈtoʊnɪn/, also known chemically as N-acetyl-5-methoxytryptamine, is a naturally occurring compound found in animals, plants, and microbes. In animals, circulating levels of the hormone melatonin vary in a daily cycle, thereby allowing the entrainment of the circadian rhythms of several biological functions. (Wikipedia)
