L-Glutamic Acid is a non-essential amino acid for human development; referred to as an excitatory amino acid (EAA) due to its role in neurotransmission. Acts as a neurotransmitter at fast synapses; agonist at kainate, NMDA and quisqualate receptors. L-Glutamic acid is one of the two amino acids…

D-Biotin is a growth factor present in small amounts in every living cell. It is involved in naturally occurring carboxylation reactions. It occurs mainly bound to proteins or polypeptides. It is more abundant in the liver, kidney, pancreas, yeast and milk. Biotin levels are higher in cancerous…

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. …

An essential amino acid.

L-Cysteine is a proteinogenic amino acid incorporated into proteins as directed by the genetic code. The thiol-side chain participates in a variety of oxidation/reduction reactions within the cell. The side chain participates in the formation of β bonds that modulate the secondary and ternary…

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. L-Glutamine is an essential amino acid that is a crucial component of culture media that serves as a major energy source…

Amino acid found in human plasma and thyroid gland, similar to thyroxine. T3 is a thyroid hormone that increases rates of proteins synthesis, stimulates the breakdown of cholesterol, and effects embryonic development. In cell culture, T3 regulates cell differentiation and protein expression.
