Putrescine is a biogenic polyamine and precursor of spermidine. It is formed via decarboxylation of ornithine or by decarboxylation of arginine followed by hydrolysis. Binds to the polyamine modulatory site of the NMDA receptor and potentiates NMDA-induced currents; precursor of spermidine.

L-Cysteine is a sulfur containing amino acid that is closely related to Cystine. Naturally occurring non-essential amino acid Used to manufacture L-glutathione and L-taurine NMDA glutamatergic receprot agonist L-cysteine is used in producing antioxidants. It also promotes healing…

N-Acetyl-L-cysteine is an acetylated amino acid with antioxidant and mucolytic properties for isolation of mycobacteria from sputum. As a mucolytic agent, N-Acetyl-L-cysteine serves to dissipate disulfide bonds across mucoproteins, loosening and clearing the viscosity of sputum. …

L-Lysine is an essential proteinogenic α amino acid. It contains an N-butyl amino group in the side chain, and this moiety is protonated at physiological pH. In addition, L-lysine is one of the two amino acids that are degraded to give ketone bodies (a ketogenic amino acid). L-Lysine is…

Carnitine is a quaternary amine that occurs naturally in most mammalian tissue. It is present in relatively high concentrations in skeletal muscle and heart where it is involved in regulating energy metabolism. It shifts glucose metabolism from glycolysis to glycogen storage and enhances the…

L-Glutamine, the uncharged and amidated analog of L-glutamic acid, is an important amino acid for the incorporation of NH4+ into biomolecules. It is biosynthesized from NH4+ and glutamate via the enzyme glutamate synthetase. In turn, degradation of glutamine to free the ammonia moiety is mediated…
