5-hydroxy Indole-3-acetic Acid

5-hydroxy Indole-3-acetic acid (5-HIAA) is a metabolite of the monoamine neurotransmitter serotonin (5-HT, Cay-14332). It is formed from serotonin via a 5-hydroxy indole-3-acetaldehyde intermediate by aldehyde dehydrogenase. 5-HIAA has been used as a biomarker for the detection of neuroendocrine tumors. Brain levels of 5-HIAA are decreased in patients with severe Alzheimer's disease.Formal Name: 5-hydroxy-1H-indole-3-acetic acid. CAS Number: 54-16-0.
