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.
Structure and properties [edit]. BMAA is a derivative of the amino acid alanine with an aminomethyl group on the side chain. This non-proteinogenic amino acid is classified as a polar base.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.
