N-Carbobenzyloxy-D-asparagine Usage And Synthesis

Chemical Properties

White solids or powder

Uses

Nα-Cbz-D-asparagine is an N-Cbz-protected form of D-Asparagine (A788960). D-Asparagine is an isomer of L-Asparagine (A790005) and is used by bacteria (such as Saccharomyces cerevisiae) as a sole nitrogen source for replication. L-Asparagine is also a competitive inhibitor of staphylococcal L-asparaginase and is used as a reagent to synthesize peptide antibiotics.
