| Common Name | Imidazolelactic acid |

| Description | 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 ). |
