Description
5-hydroxy Indole-3-acetic acid (5-HIAA) is the primary metabolite of serotonin (5-HT; ). It is formed when 5-HT is metabolized by monamine oxidase and aldehyde dehydrogenase in the liver. 5-HIAA is excreted in urine and has been used as a biomarker for detection of neuroendocrine tumors and an internal standard for the quantification of serotonin metabolism in rat brain using mass spectrometry. 5-HIAA has also been associated with autism, insomnia, and chronic migraine.

Uses
5-Hydroxyindole-3-acetic acid is a major serotonin metabolite.
Definition
ChEBI: A member of the class of indole-3-acetic acids that is indole-3-acetic acid substituted by a hydroxy group at C-5.
General Description
5-Hydroxyindole-3-acetic acid (5-HIAA) is the catabolic end product of serotonin pathway. 5-HIAA is present in body fluids like cerebrospinal fluid (CSF), blood and urine. The expression levels of 5-HIAA is different among the normal and cancer patients. Sepiapterin reductase deficiency results in low level of 5-HIAA in CSF. 5-HIAA level is low in CSF in patients with bipolar 1 disorder with childhood attention-deficit hyperactivity disorder (ADHD).
Mechanism of action
The primary
product of the metabolism of serotonin. Formed by the oxidative
deamination of serotonin by monoamine oxidase, presumably
the A isozyme, 5-HIAA is subsequently cleared by an
active transport mechanism. Unlike serotonin, 5-HIAA is not a
neurotransmitter and thus its formation contributes to the termination
of the synaptic actions of serotonin. Inhibition of
monoamine oxidase activity enhances and prolongs the actions
of serotonin.
Check Digit Verification of cas no
The CAS Registry Mumber 54-16-0 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 5 and 4 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 54-16:
(4*5)+(3*4)+(2*1)+(1*6)=40
40 % 10 = 0
So 54-16-0 is a valid CAS Registry Number.
