Cholesterol is the principal sterol of the higher animals, found in all body tissues. It is the main constituent of gallstones and all biological membranes. Approximately 25% of total brain lipid is cholesterol. Cholesterol is suitable for use in liposome preparations.

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…

Trehalose is a natural alpha-linked non–reducing disaccharide formed by an α,α-1,1-glucoside bond between two α-glucose units which yields 2 moles of D-glucose upon acid hydrolysis. Has 90% of the calorific content of sucrose. Inhibits polyglutamine-mediated protein…

L-Serine is one of the two biological amino acids with a hydroxyl substituted side chain, and thus is hydrophilic in character. L-serine is used in the study of influence of pulsed applications of serine on polyglucose synthesis by Fusobacterium nucleatum cultures. Supplementation of minimal…
