A generic term for a biogenic amine which is present in very low amounts in mammalian tissues but is not known to have a functional role.
While some trace amines act as neurotransmitters in invertebrates, the extent to which they function as such in vertebrates is speculative. They may be involved in various physiological functions.
Examples, trace amines Beta-phenylethylamine (b-PEA), p-tyramine (p-TYR), octopamine and tryptamine.
