A member of a class of protein-like molecules made in the brain. Neuropeptides consist of short chains of amino acids, with some functioning as neurotransmitters and some functioning as hormones.
Neuropeptide K. Neuropeptide K seems to be the tachykinin which is present in highest concentrations in plasma as well as in acetic acid extracts of tumour tissues. It is highly biologically active, and may therefore contribute to the clinical symptoms of carcinoid syndrome.
Also known as Neurokinin K
