l phenylalanine 15n

L-Phenylalanine-15N ((S)-2-Amino-3-phenylpropionic acid-15N) is the 15N-labeled L-Phenylalanine. L-Phenylalanine is an essential amino acid isolated from Escherichia coli . L-Phenylalanine is a α2δ subunit of voltage-dependent Ca + channels antagonist with a K i of 980 nM. L-phenylalanine is a competitive antagonist for the glycine- and glutamate-binding sites of N-methyl-D-aspartate receptors (NMDARs) ( K B of 573 μM ) and non-NMDARs , respectively. L-Phenylalanine is widely used in the production of food flavors and pharmaceuticals.

L-Valine-13C5-15N is the 13C and 15N labeled compound of L-Valine. L-Valine has a CAS number of 72-18-4. A branched-chain essential amino acid that has stimulant activity. It promotes muscle growth and tissue repair. It is a precursor in the penicillin biosynthetic pathway.

L-Glutamic acid-15N is the 15N-labeled version of L-Glutamic acid, an excitatory neurotransmitter and an agonist at metabotropic, kainate, NMDA, and AMPA glutamate receptor subtypes. It directly activates the release of dopamine (DA) from dopaminergic terminals.
