What is the Difference Between Glutamine and Glutamate?
🆚 Go to Comparative Table 🆚Glutamine and glutamate are two distinct amino acids that serve different biological functions and purposes. Here are the key differences between them:
- Essentiality: Glutamine is a conditionally essential amino acid, meaning it is made by the human body and is considered nonessential under normal circumstances. However, in certain situations such as major trauma, surgery, or intense chemotherapy, it becomes essential. On the other hand, glutamate is a nonessential amino acid, which means it can be synthesized by the body and is not required to be obtained through diet.
- Chemical Formula: The chemical formula for glutamine is C5H10N2O3, while glutamate has the chemical formula C5H9NO4.
- Function: Glutamine plays a role as an energy source and a donor for carbon and nitrogen in various cells, such as lymphocytes and enterocytes. It also improves nitrogen balance and preserves the concentration of glutamine in skeletal muscle. Glutamate, on the other hand, serves as an excitatory neurotransmitter in the brain, energizing nerve cells.
- Supplementation: Glutamine supplementation is used by almost everyone under proper conditions, as it can help with post-workout muscle soreness and recovery, immune health, and treatment of inflammatory bowel disease to rebuild gut lining. However, supplementation with glutamate is only beneficial for people who are deficient in protein and should only be done under a physician's instruction. Excessive glutamate supplementation can overstimulate the brain and cannot be used by people with existing neurological diseases and disorders.
In summary, glutamine and glutamate are different amino acids with distinct functions and purposes. Glutamine is a conditionally essential amino acid involved in various cellular processes, while glutamate is a nonessential amino acid that serves as an excitatory neurotransmitter in the brain. Supplementation with these amino acids should be done under proper guidance and for the appropriate purposes.
Comparative Table: Glutamine vs Glutamate
Here is a table comparing the differences between glutamine and glutamate:
Characteristic | Glutamine | Glutamate |
---|---|---|
Charge | Neutrally charged | Divalent anion |
Chemical Formula | C5H10N2O3 | C5H9NO4 |
Amino Acid Type | Conditionally essential | Non-essential |
Function | Energy source, carbon and nitrogen donor | Excitatory neurotransmitter |
Skeletal Muscle Content | 80% of the body's glutamine supply | Recycled and made by glial cells in the brain |
Glutamine and glutamate are both amino acids, but they have different charges, chemical formulas, and functions in the body. Glutamine is a conditionally essential amino acid that acts as an energy source and a donor for carbon and nitrogen, while glutamate is a non-essential amino acid that serves as an excitatory neurotransmitter in the brain.
