N-Cbz-L-Aspartic Acid (Z-Asp-OH) (CAS: 1152-61-0) is an N-Cbz-protected form of L-Aspartic Acid. 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.
Z-amino acid, can be used in peptide synthesis, can be also used as an organic synthesis intermediate, pharmaceutical intermediate, biochemical reagent or chemical reagent.
