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.

Poly-lysine is a polycation which binds to DNA, red cell membrane and any negatively charged protein. It is typically used as a coating substrate for culture dishes, slides, etc. It enhances electrostatic interaction between negatively charged ions of the cell membrane and the culture surface. When…

D-Biotin is a growth factor present in small amounts in every living cell. Involved in carboxylation reactions Occurs mainly bound to proteins or polypeptides Abundant in the liver, kideny, pancreas, yeast, and milk Levels are higher in cancerous tumors than in normal tissues …

L-Tryptophan is an amino acid precursor of serotonin and melatonin.

L-histidine is an essential amino acid with a basic side chain, and is hydrophilic in character. It contains an imidazole group in the side chain. Histidine is biosynthesized from ATP, 5-phosphoribosyl-1-pyrophosphate (PRPP), and glutamine. In turn, histidine is degraded to glutamate by histidase,…
