Î²-Methylamino-L-alanine, or BMAA, is a non-proteinogenic amino acid produced by cyanobacteria.tudies on human brain tissue of ALS/PDC, ALS, Alzheimer's disease, Parkinson's disease, Huntington's disease and neurological controls indicated that BMAA is present in non-genetic progressive neurodegenerative disease but not in controls or genetic-based Huntington's disease.
Abstract The toxin ss-N-methylamino-L-alanine (BMAA) was proposed to contribute to the ALS/Parkinsonism-dementia complex of Guam (ALS/PDC) based on its presence in cycad seeds, which constituted a dietary item in afflicted populations, and its ability to induce a similar disease phenotype in primates.n past studies we found that toxic and excitatory effects of BMAA on cultured neurons were dependent upon the presence of bicarbonate in the medium, and suggested that formation of a carbamate adduct of the side-chain amino group might produce structures capable of activating glutamate receptors.
