Ethanethiol is the organic compound with the formula CH3CH2SH. It consists of an ethyl group, CH3CH2, abbreviated Et, attached to a thiol group, SH, and the entire molecule is often abbreviated EtSH.he compound is structurally similar to ethanol by replacement of O by S. This change leads to many different properties, the most infamous of which is the strong odour of EtSH. Ethanethiol is also more volatile than ethanol due to its diminished ability to engage in hydrogen bonding.
Not to be confused with serotonin (5-hydroxytryptamine, 5-HT). 5-Hydroxytryptophan (5-HTP), also known as oxitriptan (INN), is a naturally occurring amino acid and chemical precursor as well as a metabolic intermediate in the biosynthesis of the neurotransmitters serotonin and melatonin from tryptophan.-HTP is decarboxylated to serotonin (5-hydroxytryptamine or 5-HT) by the enzyme aromatic-L-amino-acid decarboxylase with the help of vitamin B6. This reaction occurs both in nervous tissue and in the liver. 5-HTP crosses the bloodâbrain barrier, while 5-HT does not.
