Glutamic acid (symbol Glu or E; [4] the anionic form is known as glutamate) is an α-amino acid that is used by almost all living beings in the biosynthesis of proteins.It is a non-essential nutrient for humans, meaning that the human body can synthesize enough for its use.
Theanine / ˈ θ iː ən iː n /, commonly known as L-theanine and sometimes L-gamma-glutamylethylamide or N 5-ethyl-L-glutamine, is an amino acid analogue of the proteinogenic amino acids L-glutamate and L-glutamine and is found primarily in particular plant and fungal species.
Glutamate is a very major constituent of a wide variety of proteins; consequently it is one of the most abundant amino acids in the human body. [1] Glutamate is formally classified as a non-essential amino acid, because it can be synthesized (in sufficient quantities for health) from α-ketoglutaric acid, which is produced as part of the citric acid cycle by a series of reactions whose ...
Subjects who were treated with L-glutamine oral powder experienced fewer hospital visits for pain treated with a parenterally administered narcotic or ketorolac (sickle cell crises), on average, compared to subjects who received a placebo (median 3 vs. median 4), fewer hospitalizations for sickle cell pain (median 2 vs. median 3), and fewer ...
In enzymology, a L-glutamate oxidase (EC 1.4.3.11) is an enzyme that catalyzes the chemical reaction L-glutamate + O 2 + H 2 O ⇌ {\displaystyle \rightleftharpoons } 2-oxoglutarate + NH 3 + H 2 O 2 The 3 substrates of this enzyme are L-glutamate , O 2 , and H 2 O , whereas its 3 products are 2-oxoglutarate , NH 3 , and H 2 O 2 .
In enzymology, a glutamin-(asparagin-)ase (EC 3.5.1.38) is an enzyme that catalyzes the chemical reaction. L-glutamine + H 2 O L-glutamate + NH 3. Thus, the two substrates of this enzyme are L-glutamine and H 2 O, whereas its two products are L-glutamate and NH 3.
The two products are succinate semialdehyde and L-glutamate. This enzyme belongs to the family of transferases , specifically the transaminases , which transfer nitrogenous groups. The systematic name of this enzyme class is 4-aminobutanoate:2-oxoglutarate aminotransferase .
Glutaminase (EC 3.5.1.2, glutaminase I, L-glutaminase, glutamine aminohydrolase) is an amidohydrolase enzyme that generates glutamate from glutamine. Glutaminase has tissue-specific isoenzymes. Glutaminase has an important role in glial cells. Glutaminase catalyzes the following reaction: Glutamine + H 2 O → glutamate + NH + 4
