Glutamate acid is an acidic amino acid, colorless crystal, umami, slightly soluble in water, but soluble in hydrochloric acid solution.It is found in large amounts in cereal proteins and is found in large amounts in animal brains. Glutamate plays an important role in protein metabolism and is involved in many important chemical reactions in animals, plants and microorganisms. Monosodium glutamate contains a small amount of glutamate.
