L-Glutamine by MP Biomedicals is a high purity amino acid. This is an -amino acid which contains an -amino group, an -carboxylic acid group, and a side chain amide which replaces the carboxylic acid side chain of glutamic acid, classifying it as a charge neutral (at physiological pH), polar amino acid. This preparation is available as a white crystalline powder which is soluble in water. It is classified as non-essential and conditionally essential in humans, since the body can usually synthesize sufficient amounts of it, but in some cases it is not enough. CAS No. 56-85-9 Quantity Provided: 25 gm per pack Molecular Formula: C5H10N2O3 Molecular Weight: 146.1 Soluble in water L-Glutamine is widely used in chemical and biological sectors. Glutamine is the most abundant non-essential amino acid in the human body, and one of the few amino acids that can directly cross the bloodbrain barrier. It has been used as an oral powder to reduce severe complications of sickle cell disease in people aged 5 years and older with the disorder. L-glutamine is a component of various microbiological media, and is added for optimal cell performance in a culture medium.
