Document Summary
Non-traditional neurotransmitters do not satisfy the following criteria for a neurotransmitter but function like neurotransmitters. Released from presynaptic terminals after neuron fires. Existence of receptors on postsynaptic neurons: peptides. Structure consists of 2 or more amino acids. Synthesis not synthesised from smaller compounds but are products of larger compounds (polypeptides) being broken down into peptides within the neuron before release at the terminal button. Naturally occurring molecules including fats, waxes and many others. Biological functions include energy storage, signalling and providing the structural components of cell membranes. Synthesis pathways remain unclear for many lipids that serve as neurotransmitters/modulators. Subunits of nucleic acids, the heredity-controlling components of all living cells (eg. dna and rna) Usually obtained by chemical/enzymatic breakdown of nucleic acids -> consists of a molecule of sugar linked to a nitrogen-containing compound. Modulating the modulators co-transmitters that serve to modulate the release of other transmitters.
