(2R)-2-[(2-methylpropan-2-yl)oxycarbonylamino]pentanedioic acid

N-Boc-D-glutamic Acid is an N-Boc-protected form of D-Glutamic acid. D-Glutamic acid is an unnatural isomer of L-Glutamic acid, and is found in bacterial cell wall peptidoglycan of gram-positive and gram-negative bacteria. D-Glutamic acid also occurs as poly-gamma-Glutamic acid, which is a weak immunogen but is capable of acting as a hapten (a small molecule that induces the production of antibodies, as well as binding to them).
