Application

DL-Glutamic acid is a racemic mixture of the proteinogenic amino acid L-Glutamic acid and the non-proteinogenic amino acid D-Glutamic acid. DL-Glutamic acid is used ito study its mechanisms of crystal formation and self-assembly on surfaces and copolymer development.

Biochem/physiol Actions

Excitatory amino acid neurotransmitter that is an agonist at kainate, NMDA, AMPA, and metabotropic glutamatergic receptors.

In this work, we synthesized chiral mesoporous silica (CMS) spheres, which can be used as a potential candidate for chiral separation. The CMS spheres with controllable pore sizes (of 2-3 nm) and high surface areas of ca. 614 m(2) g(-1)

In this communication, we demonstrate that chiral self-assembled monolayers can be used for polymorphism control of chiral crystals. We studied the crystallization of DL-glutamic acid on chiral self-assembled monolayers and showed that crystallization of DL-glutamic acid on the chiral SAMs
