Major degradation product of serotonin?

Explanation:
Serotonin is broken down primarily by monoamine oxidase into 5-hydroxyindoleacetaldehyde, which is then converted to 5-hydroxyindoleacetic acid. This metabolite, 5-HIAA (also called 5-hydroxy-3-indolacetic acid), is the major product excreted in urine and is commonly measured to assess serotonin turnover, such as in carcinoid tumors. The other compounds come from different neurotransmitters: vanillylmandelic acid is a catecholamine metabolite, homovanillic acid is a dopamine metabolite, and choline is a precursor for acetylcholine.
