E640 Flavour enhancer

E640 is not widely used in foods for its nutritional value, except in infusions. Instead, glycine's role in food chemistry is as a flavoring. It is mildly sweet, and it counters the aftertaste of saccharine. It also has preservative properties, perhaps owing to its complexation to metal ions. Metal glycinate complexes, e.g. copper- glycinate are used as supplements for animal feeds.E640 is an intermediate in the synthesis of a variety of chemical products. It is used in the manufacture of the herbicides glyphosate, iprodione, glyphosate, imiprothrin, and eglinazine. It is used as an intermediate of medicine such as thiamphenicoL.E640 is a significant component of some solutions used in the SDS-PAGE method of protein analysis. It serves as a buffering agent, maintaining pH and preventing sample damage during electrophoresis. E640 is also used to remove protein-labeling antibodies from Western blot membranes to enable the probing of numerous proteins of interest from SDS-PAGE gel. This allows more data to be drawn from the same specimen, increasing the reliability of the data, reducing the amount of sample processing, and a number of samples required. This process is known as stripping.
