4-Imidazolone-5-propionic acid
4-Imidazolone-5-propanoate is a metabolite of histidine metabolism. It is produced from urocanic acid by the enzyme urocanate hydratase [EC:4.2.1.49]. 4-Imidazolone-5-propionic acid can spontaneously decay to 4-oxoglutaramate or formylisoglutamine. It is also converted to N-forminimo-L-glutamate by the enzyme imidazolonepropionase [EC:3.5.2.7]. [HMDB] 4-Imidazolone-5-propanoate is a metabolite of histidine metabolism.

1-Naphthaldehyde
1-naphthaldehyde, also known as alpha-naphthal or 1-formylnaphthalene, is a member of the class of compounds known as naphthalenes. Naphthalenes are compounds containing a naphthalene moiety, which consists of two fused benzene rings. 1-naphthaldehyde is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 1-naphthaldehyde can be found in a number of food items such as black crowberry, devilfish, other soy product, and chinese bayberry, which makes 1-naphthaldehyde a potential biomarker for the consumption of these food products. This compound belongs to the family of Naphthalenes. These are compounds containing a naphthalene moiety, which consists of two fused benzene rings.
2-Naphthaldehyde
This compound belongs to the family of Naphthalenes. These are compounds containing a naphthalene moiety, which consists of two fused benzene rings.
Imidazole lactate
Imidazolelactic acid is the component of normal human urine. (PMID: 5856262). histidine loading causes an increase in the excretion of imidazolelactic acid. (PMID: 6021220). During pregnancy the values for imidazolelactic acid in urine is increased 3-fold. An interaction of allergic reactions and anomalies in the metabolism of the sex hormones are considered to form the basis of the pregnancy-specific illnesses that were studied. (PMID: 5789877). Urinary excretion of imidazolelactic acid is also an indication for folic acid and vitamin B12 deficiency. (PMID: 4645251). Imidazolelactic acid is the component of normal human urine.
