Description
A naturally occurring, non-essential amino acid found in wheat gluten, vegetable products, and animals. Glutamic acid was first isolated in 1865. The body synthesizes glutamic acid during carbohydrate metabolism. Glutamic acid also occurs in many plants. It is a very polar molecule that plays the role of an excitatory amino acid (EAA) in neurotransmission.
Synonyms and Related Terms
