Amino acids can exist in two stereoisomeric forms, D-amino (dextrorotatory) and L-amino (levorortatory)[1]. Most amio acid exist in the L-isomer form in living organisms. However in recent years with major technological advancements in science D-isomers have also been found in living things[2]. D-isomers are mainly found in bacteria in the peptidoglycan cell wall.

D-alanine and D-glutamine are the main components in the peptidoglycan cell wall and can be associated with antibiotic resistance in bacteria[3].
