Ammonium Glutamate

It was generally found that double chain ammonium glutamic acid amphiphiles of the general formula 2Cn-Glu-CmN+ (15) typically form typical bilayer vesicles above their phase transition temperature.118 It is interesting to refer to the compound 2Ci2-Glu-CnN+ (15b, n = 12)111,119 in which the predominant superstructures were flexible filaments with...

In practise, MSG (which corresponds to the completely dissociated form of the acid) is used almost exclusively to improve the flavour of foods. It is permitted world-wide, although in some countries and some types of foods maximum concentration limits apply. Other salts of glutamic acid that are occasionally used are potassium, calcium, and ammonium glutamates. These are not permitted world-wide.

JECEA reviewed the safety studies of glutamate and endorsed its safety by allocating an Acceptable Daily Intake (ADI) for L-glutamic acid and its monosodium, potassium, ammonium, calcium, and magnesium salts as being "not specified." The scientific committee for food of EC concurred (40).

Glutamic acid and its salts (especially the sodium salt) enhance the flavour of many convenience foods. Bejaars et al. (1996) described the determination of free glutamic acid in soups, meat products and Chinese food. The method involves hot water extraction of test portions followed by filtration and dilution. The extracts were treated with N,N-dimethyl-2-mercapto-ethyl-ammonium chloride and o-phtaldialdehyde to convert glutamic acid into a stable fluorescent, l-alkylthio-2-alkyhsoindole. Homocysteic acid was used as the internal standard. Separation was made on a Ci8 column, eluted with... 

If 15N ammonium citrate was administered, and glutamate, aspartate, and glycine isolated from liver and intestinal wall protein, all showed 15N uptake. From the results of labeling studies, Schoenheimer finished his Edward K.Dunham lectures in Harvard in 1941 with the phrase— the structural materials [of the body] are in a steady state of flux. The classical picture must thus be replaced by one which takes account of the dynamic state of body structure —an idea which has become an integral part of biochemistry since that time, and which was almost totally dependent on the introduction of isotopes for its discovery.
