L-Glutamic acid-¹³C₅ is the ¹³C-labeled L-Glutamic acid. L-Glutamic acid acts as an excitatory transmitter and an agonist at all subtypes of glutamate receptors (metabotropic, kainate, NMDA, and AMPA). L-Glutamic acid shows a direct activating effect on the release of DA from dopaminergic terminals.

L-Ornithine-d₇ hydrochloride is the d₇-labeled L-Ornithine hydrochloride (HY-W017018). L-Ornithine hydrochloride is an orally active CaSR and p38 activator. L-Ornithine hydrochloride inhibits ROS and supports urea cycle function. L-Ornithine hydrochloride can be used to study kidney diseases involving proximal tubular cell damage caused by oxidative stress or crystallopathy, as well as research related to anxiety disorders.

L-Leucine-¹³C is the ¹³C-labeled L-Leucine. L-Leucine is an essential branched-chain amino acid (BCAA), which activates the mTOR signaling pathway.

L-Alanine-d₄ is the deuterium labeled L-Alanine. L-Alanine is a non-essential amino acid, involved in sugar and acid metabolism, increases immunity, and provides energy for muscle tissue, brain, and central nervous system.

L-Cysteine-¹³C₃,¹⁵N is the ¹³C- and ¹⁵N-labeled L-Cysteine. L-Cysteine is a conditionally essential amino acid, which acts as a precursor for biologically active molecules such as hydrogen sulphide (H2S), glutathione and taurine. L-Cysteine suppresses ghrelin and reduces appetite in rodents and humans.

L-Valine-¹³C₅ ((S)-Valine-¹³C₅) is the ¹³C-labeled L-Valine (HY-N0717). L-Valine ((S)-Valine) is a nonlinear semiorganic material. L-Valine causes lipid peroxidation and accumulation of malondialdehyde (MDA), exhibits inhibitory activity against cyanobacteria. L-Valine inhibits multidrug-resistant bacteria through activation of PI3K/Akt signaling pathway and inhibition of arginase.

L-Cystine-d₄ is the deuterium labeled L-Cystine. L-Cystine is an amino acid and intracellular thiol, which plays a critical role in the regulation of cellular processes.

L-Glutamic acid-d₅ is the deuterium labeled L-Glutamic acid. L-Glutamic acid acts as an excitatory transmitter and an agonist at all subtypes of glutamate receptors (metabotropic, kainate, NMDA, and AMPA). L-Glutamic acid shows a direct activating effect on the release of DA from dopaminergic terminals.

L-Proline-¹³C₅ is the ¹³C-labeled L-Proline. L-Proline is one of the twenty amino acids used in living organisms as the building blocks of proteins.

L-Leucine-¹³C₆,¹⁵N is the ¹³C- and ¹⁵N-labeled L-Leucine. L-Leucine is an essential branched-chain amino acid (BCAA), which activates the mTOR signaling pathway.

L-Asparagine-¹⁵N₂ monohydrate is the ¹⁵N-labeled L-Asparagine monohydrate (HY-W017443). L-Asparagine monohydrate is an essential amino acid for leukemic cells and a substrate for L-Asparaginase. L-Asparaginase is a potent anti-leukemic enzyme that promotes asparagine (Asn) and glutamine (Gln) depletion and inhibits protein biosynthesis in lymphoblasts. Removal of L-asparagine from plasma by L-Asparaginase results in inhibition of RNA and DNA synthesis and subsequent apoptosis. L-Asparaginase has cell-killing ability in vitro and in vivo, and selectively inhibits the growth of cancer cells with low asparagine synthetase (AASNS) expression. L-Asparagine monohydrate can be used as a biomarker and sensor for the study of childhood acute lymphoblastic leukemia.

L-Methionine-¹³C is the ¹³C-labeled L-Methionine. L-Methionine is the L-isomer of Methionine, an essential amino acid for human development. Methionine acts as a hepatoprotectant.

L-Methionine-¹³C,d₃ is the ¹³C- and deuterium labeled L-Methionine. L-Methionine is the L-isomer of Methionine, an essential amino acid for human development. Methionine acts as a hepatoprotectant.

L-Proline-d₃ is the deuterium labeled L-Proline. L-Proline is one of the twenty amino acids used in living organisms as the building blocks of proteins.

L-Aspartic acid-¹³C₄ is the ¹³C-labeled L-Aspartic acid (HY-N0666). L-Aspartic acid is a NMDA receptor agonist and acidic amino acid. L-Aspartic acid has no independent analgesic activity. L-Aspartic acid can antagonize the analgesic effects of D-Aspartic acid and Morphine. L-Aspartic acid regulates polymorph transformation, crystal growth/aggregation and nucleation processes of calcium carbonate, and can serve as a biomineralization template. L-Aspartic acid promotes burst firing of central neurons. L-Aspartic acid can be used in studies related to cerebral ischemia and epilepsy.

L-Methionine-d₃ is the deuterium labeled L-Methionine. L-Methionine is the L-isomer of Methionine, an essential amino acid for human development. Methionine acts as a hepatoprotectant.

Creatine-d₅ (monohydrate) is the deuterium labeled Creatine monohydrate. Creatine monohydrate, an endogenous amino acid derivative, plays an important role in cellular energy, especially in muscle and brain.

Leucine-¹³C₆ is the ¹³C-labeled L-Leucine. L-Leucine is an essential branched-chain amino acid (BCAA), which activates the mTOR signaling pathway.

Glycine-d₅ is the deuterium labeled Glycine. Glycine is an inhibitory neurotransmitter in the CNS and also acts as a co-agonist along with glutamate, facilitating an excitatory potential at the glutaminergic N-methyl-D-aspartic acid (NMDA) receptors.

L-Aspartic acid-d₃ is the d₃-labeled L-Aspartic acid (HY-N0666). L-Aspartic acid is a NMDA receptor agonist and acidic amino acid. L-Aspartic acid has no independent analgesic activity. L-Aspartic acid can antagonize the analgesic effects of D-Aspartic acid and Morphine.
