D-Alanine is a chemical compound that has the molecular formula C3H7NO2 and the molecular weight 89.09 g/mol. It is one of the two optical isomers of alanine, an amino acid that is found in proteins. D-Alanine is not found in proteins, but it is used in bacterial cell wall biosynthesis as a component of peptidoglycan. D-Alanine can also act as a substrate for some enzymes, such as alanine racemase, which converts it to L-alanine. D-Alanine can also bind to some antibiotics, such as vancomycin, and interfere with their activity.


D-Alanine has several uses in biological and chemical research.It can be used tostudythe function and regulation of enzymes that are involved in bacterial cell wall synthesis, such as alanine racemase and D-alanine carboxypeptidase.It can also be used toprobethe binding mechanism and specificity of antibiotics that target the bacterial cell wall, such as vancomycin and teicoplanin.D-Alanine is not used by humans to make proteins, but it may have somebeneficial effectson glucose metabolism, hypoglycemia prevention, and tryptophan and vitamin B-6 breakdown. However, more research is needed to confirm its safety and efficacy for these purposes.

Applications D-Alanine is an amino acid that is commonly found in bacteria, such as Streptococcus faecalis. It is essential for the biosynthesis of peptidoglycan crosslinking sub-units that are used for bacterial cell walls. D-Alanine is also known to cause cytotoxic oxidative stress in brain tumour cells.
