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.

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.
