Definition of neuropeptide in English:



  • Any of a group of compounds which act as neurotransmitters and are short-chain polypeptides.

    • ‘Recently, several studies brought to light the biophysical properties of tachykinin neuropeptides.’
    • ‘TppII is 38% identical to human and rat proteins that degrade neuropeptides by attacking their amino termini and releasing three amino acid fragments.’
    • ‘Enkephalins are flexible neuropeptides and their conformation is dependent on their environment.’
    • ‘Most biologically active peptide hormones and neuropeptides are produced from larger inactive precursor proteins by endoproteolytic cleavage and further processing within the secretory pathway.’
    • ‘To date, we know of approximately 300 substances that act as neurotransmitters, including endorphins, neuropeptides, adrenaline, noradrenaline and acetylcholine.’
