Glutamic Acid is an amino acid that plays a crucial role in the body, particularly in protein synthesis. It is classified as a non-essential amino acid, meaning the body can produce it on its own. Glutamic acid is also important for brain function, as it acts as a neurotransmitter, helping to transmit signals between nerve cells. This amino acid is found in various foods, including meat, fish, eggs, dairy products, and certain plant-based sources like soybeans and spinach. Additionally, it is commonly used as a flavor enhancer in the form of monosodium glutamate (MSG) in many processed foods.
