(D)-ASPARTIC ACID 4-AMIDE - Reference Information
| biological activity | D-Asparagine (H-D-Asn-OH) was a competitive inhibitor of L-asparagine hydrolysis with a Ki value of 0.24 mM. D-Asparagine is the nitrogen source of yeast strains. D-Asparagine is a good substrate for external yeast asparaginase and a poor substrate for internal enzymes. |
