What is Muramyl dipeptide?

Plain description, key identifiers and synonyms

Muramyl dipeptide is a glycopeptide that is N-propionyl-L-alanyl-D-alpha-glutamine in which the pro-R hydrogen of the propionyl group has been replaced by the oxygen at position 3 of 2-acetamido-2-deoxy-beta-D-glucopyranose. A peptidoglycan constituent of both Gram-positive and Gram-negative bacteria. It has a role as an immunological adjuvant. It is a conjugate acid of a N-acetyl-beta-D-muramoyl-L-alanyl-D-isoglutamine(1-).
