Glutamate is an acidic proteinogenic amino acid and is a non-essential amino acid. Glutamate is an important molecule in cellular metabolism. Glutamate is a critical excitatory neurotransmitter in the mammalian nervous system. In humans, glutamate is involved in disposal of excess or waste nitrogen and amino acid degradation. Glutamate is also involved in memory and learning, and is associated with diseases like lathyrism, amyotrophic lateral sclerosis, Alzheimer's disease, some forms of mental retardation and autism. Glutamic acid is also present in many foods and is used as a flavor enhancer in food industry.

The Glutamate Colorimetric Assay Kit provides a sensitive, fast and convenient way for detection of glutamate in various samples based on colorimetric method. The Glutamate Enzyme Mix recognizes glutamate as a specific substrate leading to proportional color development, which can be detected by colorimetric (spectrophotometry at λ = 450 nm) method.
