Description

L-Aspartic acid 4-tert-butyl ester is a protected form of L-Aspartic acid (A790024). L-Aspartic acid is a nonessential amino acid that is used to biosynthesize other amino acids within the human body. L-Aspartic acid also increases membrane conductance of mammalian neurons by voltage-dependent means, causing depolarization and nerve impulses that travel to key areas of the central nervous system.
