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 by glutaminase. Glutamine also participates in acid-base regulation in vivo.

Soluble in distilled water. Soluble in 0,1 M potassium phosphate buffer, pH 6,0 (monobasic potassium phosphate adjusted to pH 6,0 with 1,0 M potassium hydroxide) (10 mg/ml yields a clear, red-brown solution). Solutions of HRP can be kept refrigerated for up to a year while maintaining practically undiminished activity. Optimal pH is 6,0 to 6,5 (activity at pH 7,5 is 84% of the maximum). The enzyme is most stable in the pH range of 5,0 to 9,0 (Lit.).

Albumins are a group of acidic proteins which occur in the body fluids and tissues of mammals and in some plant seeds. Serum and plasma albumin is carbohydrate-free and comprises 55 to 62% of the protein present. However, only about 40% of the total albumin in the body is in the circulating plasma at one time with the remainder being in extracellular spaces with which there is, in general, equilibration about every 24 hours.

Sodium pyruvate is used by cells as an easily accessible carbohydrate source. Additionally, it is involved with amino acid metabolism and initiates the Kreb′s cycle. The 100 mM solution should be diluted 1:100 for most cell culture. The use of sodium pyruvate in Wallen fermentation medium to enhance the conversion of oleic acid to 10-ketostearic acid by Bacillus sphaericus has been described. A protocol that uses sodium pyruvate to establish stably transfected human B cell lines has been published. It improves coliform recovery when present in culture medium.

Glutathione is the major low molecular weight thiol compound of the living plant or animal cell. It is a tripeptide with a gamma peptide linkage between the amine group of cysteine (which is attached by normal peptide linkage to a glycine) and the carboxyl group of the glutamate side-chain. It is an antioxidant, preventing damage to important cellular components caused by reactive oxygen species such as free radicals and peroxides. The sulfhydryl (thiol) group (SH) of cysteine serves as a proton donor and is responsible for the biological activity of glutathione.
Glutathione suppresses human immunodeficiency virus expression in chronically infected monocytic cells. It is a useful tripeptide involved in many aspects of metabolism, including transport of g-glutanyl amino acids and reductive cleavage of disulfide bonds.
Endogenous antioxidant that plays a major role in reducing reactive oxygen species formed during cellular metabolism and the respiratory burst. Glutathione-S-transferase catalyzes the formation of glutathione thioethers with xenobiotics, leukotrienes, and other molecules that have an electrophilic center. Glutathione also forms disulfide bonds with cysteine residues in proteins. Via these mechanisms, it can have the paradoxical effect of reducing the efficacy of anti-cancer agents.
