[{"from": "human", "value": "What can you tell me about this molecule? [C][N][C][C@@H1][Branch1][=Branch1][C][=Branch1][C][=O][O][N]"}, {"from": "gpt", "value": "The molecule is a non-proteinogenic amino acid produced by cyanobacteria. It is a plant toxin found in the seeds of the cycad (division <i>Cycadophyta</i>). It is produced by cyanobacteria of the genus <i>Nostoc</i> that live on the plant's roots and exibits neurotoxic effects. Acutely, BMAA can act as an excitotoxin on glutamate receptors such as NMDA, calcium dependent AMPA and kainite receptors. The activation of the metabotropic glutamate receptor 5 is believed to induce oxidative stress in the neuron by depletion of glutathione. BMAA is also suggested to misincorporate into nascent proteins in place of L-Serine, possibly causing protein misfolding and aggregation, both hallmarks of tangle diseases, including Alzheimer's, Parkinson's and ALS, PSP and Lewy Body Disease. In-vitro research has shown that protein association of L-BMAA can be inhibited in presence of excess L-Serine. (Wikipedia)"}]
