D-Alanine is essential for the biosynthesis of peptidoglycan crosslinking sub-units that are used for bacterial cell walls.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
Applications
D-Alanine is essential for the biosynthesis of peptidoglycan crosslinking sub-units that are used for bacterial cell walls.
Solubility
Soluble in water (155 mg/ml at 20°C), ethanol (slightly), and pyridine (slightly). Insoluble in ether, and acetone.
Notes
Store in cool, dry conditions in well sealed containers. Strong oxidizing agents.
