glutamaattihaposta

Glutamaattihappo, known in English as glutamic acid, is an amino acid with the chemical formula C5H9NO4. It is one of the non-essential amino acids, meaning the human body can synthesize it and does not need to obtain it from the diet. Glutamic acid plays a crucial role in protein synthesis and metabolism.

In the human brain, glutamic acid functions as a major excitatory neurotransmitter. It is involved in numerous neuronal processes, including learning and memory. This neurotransmitter activity is mediated by its binding to specific glutamate receptors on nerve cells.

Glutamic acid is also a precursor to gamma-aminobutyric acid (GABA), the primary inhibitory neurotransmitter in the central nervous system. This conversion highlights the dual role of glutamic acid in neuronal signaling, contributing to both excitation and inhibition.

Beyond its neurological functions, glutamic acid is a component of many proteins. It can exist in its anionic form, glutamate, which is particularly relevant in its role as a neurotransmitter and in taste perception, contributing to the umami taste. Monosodium glutamate (MSG), a common food additive, is the sodium salt of glutamic acid and is used to enhance savory flavors in food.
