In the structure of N-acetyl-L-glutamic acid, C7H11NO5, each molecule is directly hydrogen bonded to four others by a total of six hydrogen bonds. Two carboxylic O atoms and the N atom are donors while all three acceptors are O atoms. There is also an intramolecular hydrogen bond with the N atom as donor and a carboxylic O atom as acceptor. The carboxyl O and H atoms are ordered. The conformation of the carbon chain with respect to the C3—C4 bond is trans as in L-glutamic acid hydrochloride, rather than gauche as in the β form of L-glutamic acid.
