14-Hydroxy-LSD is a
lysergamide
Lysergamides, also known as ergoamides or as lysergic acid amides, are amides of lysergic acid (LA). They are ergolines, with some lysergamides being found naturally in ergot as well as other fungi. Lysergamides are notable in containing embedd ...

In biochemistry, a metabolite is an intermediate or end product of metabolism.
The term is usually used for small molecules. Metabolites have various functions, including fuel, structure, signaling, stimulatory and inhibitory effects on enzymes, c ...

(LSD).
It is formed via aromatic hydroxylation at position 14 of the lysergic acid moiety and is subsequently excreted as a glucuronide conjugate.
14-Hydroxy-LSD is a major metabolite of LSD in rats and guinea pigs, where it is excreted predominantly as a glucuronide in bile and urine.
In contrast, it appears only as a minor metabolite in

Studies using human liver microsomes and urine samples have confirmed its presence in humans, but in low concentrations that are often below quantification limits.
