Descrizione generale

L-2,4-Diaminobutyric acid dihydrochloride is an unnatural amino acid derivative.

Applicazioni

L-2,4-Diaminobutyric acid dihydrochloride is suitable reagent used for the differentiation of β-N-methylamino-L-alanine from the diamino acids by using HPLC-FD, UHPLC-UV, UHPLC-MS, and triple quadrupole tandem mass spectrometry (UHPLC-MS/MS). It is suitable reagent used in the quantification of neurotoxin β-N-methylamino-L-alanine (BMAA) in seafood. It may be used as Internal standard for amino acid analysis

The neurotoxin β-N-methylamino-L-alanine (BMAA) produced naturally by cyanobacteria, diatoms and dinoflagellates can be transferred and accumulated up the food chain, and may be a risk factor for neurodegenerative diseases. This study provides the first systematic screening of BMAA exposure of

Since diverse taxa of cyanobacteria has been linked to biosynthesis of BMAA, a controversy has arisen about the detection of neurotoxic amino acids in cyanobacteria. In this context, a novel LC-MS/MS method was developed for the unambiguous determination of beta-N-methylamino-L-alanine

Basic amino acids play a key role in the binding of membrane associated proteins to negatively charged membranes. However, side chains of basic amino acids like lysine do not only provide a positive charge, but also a flexible hydrocarbon spacer

The cyanobacterial neurotoxin beta-N-methylamino-L-alanine (BMAA) has been associated with certain forms of progressive neurodegenerative disease, including sporadic Amyotrophic Lateral Sclerosis and Alzheimer's disease. Reports of BMAA in cyanobacterial blooms from lakes, reservoirs, and other water resources continue to be made
