Glutamic acid is an acidic amino acid. The molecule contains two carboxyl groups, and the chemical name is α-aminoglutaric acid. Glutamic acid was discovered in 1856 by Rixosson. It is a colorless crystal with an umami taste. It is slightly soluble in water but soluble in solution with an isoelectric point of 3.22. It exists in a large amount in cereal protein, and the content in animal brain is also higher. Glutamate occupies an important position in the process of protein metabolism in organisms, and participates in many important chemical reactions in animals, plants and microorganisms. MSG contains a small amount of glutamic acid
