glutamic acid

glutamic acid

Pronounced As: glootamik , organic compound, one of the 20 amino

acids commonly found in animal proteins. Only the l-stereoisomer

occurs in mammalian proteins. Like aspartic acid, glutamic acid has

an acidic carboxyl group on its side chain which can serve as both an

acceptor and a donor of ammonia, a compound toxic to the body. Once

glutamic acid has coupled with ammonia, it is called glutamine and

can as such safely transport ammonia to the liver, where the ammonia

is eventually converted to urea for excretion by the kidneys. Free

glutamic acid (that not incorporated into proteins) can also be

converted reversibly to á-ketoglutaric acid, an intermediate in the

Krebs cycle, and as such can be degraded to carbon dioxide and water,

or transformed into sugars. The acidic side chain of glutamic acid

confers one negative charge under most conditions to proteins in

which this amino acid is found, thus increasing the water solubility

of the protein. Monosodium glutamate (MSG), the monosodium salt of l-

glutamic acid, is widely used as a condiment. The amino acid was

isolated from wheat gluten in 1866 and chemically synthesized in

1890. It is not essential to the human diet, since it can be

synthesized in the body from the common intermediate á-ketoglutaric

acid.

I DON'T BELIEVE MCCHORMICK FAJITAS MIX IS OK
