White cryst. powder
Verwenden
D-glutamic acid is suitable for use in the structure-affinity relationship (SAR)-study of GR (glutamate racemase) enzyme and its inhibitors.
Verwenden
D-Glutamic Acid is the unnatural (R)-enantiomer of Glutamic Acid, a non-essential amino acid. Its salt form (glutamate) is an important neurotransmitter that plays a key role in long-term potentiation and is important for learning and memory. Glutamic Acid is also a key molecule in cellular metabolism.
Verwenden
D-Glutamic acid acts as a superior to alpha ketoglutarate. It helps in the growth of Lactobacillus arabinosus. It can inhibit the IgE binding to peanut allergens. It is widely used in pharmaceuticals and foods.
Definition
ChEBI: An optically active form of glutamic acid having D-configuration.
Allgemeine Beschreibung
D-Glutamic acid is an essential constituent of the bacterial peptidoglycan structure. It is added to UDP-N-acetylmuramyl-L-alanine (UDP-MurNAc-L-alanine) by the enzyme D-glutamic acid-adding enzyme (murD). This is, then, incorporated into the peptidoglycan precursor. Peptidoglycan makes up the cell walls of Gram-positive and -negative bacteria. The conversion of L-glutamate to D-glutamate by glutamate racemase (GR) enzyme is an essential step in the synthesis of peptidoglycan.
Biologische Aktivität
Excitatory amino acid acting at NMDA receptors; less active than the L-isomer.
Biochem/physiol Actions
Unnatural isomer of glutamic acid.
