Pyroglutamic acid may function in glutamate storage, and acts to oppose the action of glutamate, including in the brain. [1] It also acts on the brain's cholinergic system ; [ 4 ] Amyloid β containing pyroglutamic acid is increased in Alzheimer's disease ; this may be part of the disease process. [ 5 ]
Hydroxyproline is a major component of the protein collagen, [3] comprising roughly 13.5% of mammalian collagen. Hydroxyproline and proline play key roles for collagen stability. [4] They permit the sharp twisting of the collagen helix. [5]

It is non-essential in humans, meaning the body can synthesize it from the non-essential amino acid L-glutamate. It is encoded by all the codons starting with CC (CCU, CCC, CCA, and CCG). Proline is the only proteinogenic amino acid which is a secondary amine , as the nitrogen atom is attached both to the α-carbon and to a chain of three ...
Pregabalin, sold under the brand name Lyrica among others, is an anticonvulsant, analgesic, and anxiolytic amino acid medication used to treat epilepsy, neuropathic pain, fibromyalgia, restless legs syndrome, opioid withdrawal, and generalized anxiety disorder (GAD).
Citicoline also increases glutamate uptake by increasing expression of EAAT2, a glutamate transporter, in vitro in rat astrocytes. It is suggested that the neuroprotective effects of citicoline after a stroke are due in part to citicoline's ability to decrease levels of glutamate in the brain.
The l form is more widely occurring in nature, but the d form occurs in some special contexts, such as the bacterial capsule and cell walls of the bacteria (which produce it from the l form with the enzyme glutamate racemase) and the liver of mammals.
Glutamate + ATP + NH 3 → Glutamine + ADP + phosphate Glutamine synthetase catalyzed reaction. Glutamine synthetase uses ammonia produced by nitrate reduction, amino acid degradation, and photorespiration. [4] The amide group of glutamate is a nitrogen source for the synthesis of glutamine pathway metabolites. [5] Other reactions may take ...
