Glutamine vs. Glutamate: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on December 23, 2023
Glutamine is a non-essential amino acid used in protein synthesis and immune function, while glutamate is a key neurotransmitter and a building block for protein.

Key Differences

Glutamine is an amino acid that plays a vital role in immune function and intestinal health. Glutamate, another amino acid, acts primarily as a neurotransmitter in the brain, facilitating nerve signaling.
