Beschreibung

L-Glutamic acid, or L-2-aminopentanedioic acid, is a naturally occurring amino acid of plant and animal proteins. It has a very faint odor reminiscent of yeast or freshly baked bread. It has a mild, somewhat sweet, meat-like taste.
The average glutamic acid content of food proteins is 20 percent. Expressed as glutamic acid per 100 g of the edible portions, medium fat beef contains about 2.65 g of glutamic acid; whole liquid cow milk, 0.82 g; lean pork, 2.16 g; haddock, 2.32 g; peas, 5.58 g; soybeans, 7.01 g; commeal, 1.62 g; and whole grain wheat flour, 4.16 g. In addition, free glutamic acid is present in many vegetables, fish, and meats in small amounts (0. 005 to 0.23 g per 100 g) and as high as 2 g per 100 g in some varieties of cheese. Recent estimates of free amino acids in the milk of various species indicated that the free glutamic acid in human milk is about 0.22 g per 100 mL.
Glutamic acid and its salts are prepared commercially by hydrolysis of gluten (wheat, corn, soybean, sugarbeet protein); by fermentation from glucose-containing raw materials; the racemic acid may be resolved into the d- and ι-isomer by fractional crystallization; from 2 -cyclopentenylamine; by microbial conversion of aketoglutaric acid; or by an alternative method, using Bacillus megatherium-cereus; from fumaric acid using B. pumilus; from starch.
Glutamic acid and the hydrochloride as well as the mono-sodium, -potassium, and -ammonium salts of L-glutamic acid share similar physical properties: they are nearly odorless, white, free-flowing crystalline powders, and except for glutamic acid and glutamic acid hydrochloride, are freely soluble in water. Glutamic acid is slightly soluble and glutamic acid hydrochloride moderately soluble in water. The pH of a saturated solution is about 3.2.

Chemische Eigenschaften

L-Glutamic acid has a very faint odor reminiscent of yeast or freshly baked bread and a mild, somewhat sweet, meat- like taste This is a naturally occurring amino acid of plant and animal proteins The average glutamic acid content of food proteins is 20%, expressed as glutamic acid per 100 g of the edible portions For a detailed description, see Burdock (1997).

Chemische Eigenschaften

White cryst. powder

Occurrence

Reported as occurring in many vegetable proteins, in beef fbrin, in the chrysalis of silkworm, in the hydro- lysate of crystalline insulin Also present in other important peptides, such as glutathione, tyrocidin, folic acid, β-lactoglobulin, secretin and bacitracin, and in growth hormone

Verwenden

A non-essential amino acid. Its salt form (glutamate) is an important neurotransmitter that plays a key role in long-term potentiation and is important for learning and memory. It is also a key molecu le in cellular metabolism.

Verwenden

Amino acid/exptl antieplileptic

Definition

ChEBI: An optically active form of glutamic acid having L-configuration.

synthetische

By hydrolysis of gluten (wheat, corn or other vegetable sources); by fermentation from glucose-containing raw materials; the racemic acid may be resolved into the d- and l-isomer by fractional crystallization; from 2-cyclopentenylamine; by microbial conversion of α-ketoglutaric acid; or by an alternative method, using Bacillus megatherium-cereus; from fumaric acid, using B pumilus; from starch.

Biologische Aktivität

The predominant excitatory transmitter in the mammalian central nervous system. Acts at ionotropic and metabotropic glutamate receptors.

Sicherheitsprofil

Human systemic effects by ingestion and intravenous routes: headache and nausea or vomiting. When heated to decomposition it emits toxic fumes of NOx.

läuterung methode

Crystallise L-glutamic acid from H2O acidified to pH 3.2 by adding 4volumes of EtOH, and drying at 110o. Likely impurities are aspartic acid and cysteine. It sublimes at 170-175o/10mm. It melts at 160o with cyclisation to L-pyrrolidone carboxylic acid. [Dunn & Brophy J Biol Chem 99 224 1958, Parikh et al.
