Allgemeine Beschreibung

L-BMAA hydrochloride/β-N-methylamino-l-alanine (BMAA) is a cyanobacterial neurotoxin.

Anwendung

L-BMAA hydrochloride has been used as a standard to compare all the samples in the analysis of β-N-methylamino-l-alanine (BMAA) isomers in desert crust material. It has also been used as an additive with f/2+Si medium to treat the cells of Phaeodactylum tricornutum and Thalassiosira weissflogii to study its effect on them.

Biochem./physiol. Wirkung

L-BMAA hydrochloride helps to block the addition of heparan sulfate to glypican-1. It possesses unusual glutamate receptor binding properties. It may cause amyotrophic lateral sclerosis/Lou Gehrig′s disease.

Cyanobacteria produce a series of secondary metabolites, one of which is beta-N-methylamino-l-alanine (BMAA). BMAA is considered to be the cause of human neurodegeneration. Compared with other cyanotoxins, the role of BMAA in cyanobacteria remains unclear. To investigate this question, six

The environmental neurotoxin β-methylamino-l-alanine (BMAA) may represent a risk for human health. BMAA accumulates in freshwater and marine organisms consumed by humans. However, few data are available about the kinetics of BMAA accumulation and detoxification in exposed organisms, as well
