DON acts as a glutamine antagonist, disrupting cancer cells’ ability to utilize this essential nutrientEssential nutrients are like the irreplaceable actors in a play – your body absolutely needs them to function properly. These nutrients come from the food you eat and are used for various vital processes, including fueling your metabolism. • Synonyms: Well-documented… Read More. This disruption leads to:
- Impaired Nucleotide SynthesisImagine your body is a giant factory building lots of tiny machines called cells. To build these machines, your body needs special building blocks. • Nucleotides (say, “noo-klee-o-tides”) are kind of like Legos for your cells. They come together in different… Read More: Glutamine is crucial for creating nucleotides, the building blocks of DNA and RNAImagine DNA is the big boss in the cell, holding all the important instructions. But the boss can’t do everything itself, right? That’s where RNA comes in – it’s like a messenger carrying out the boss’s orders! What is RNA?… Read More. By blocking glutamine, DON hinders DNA replication and repair, ultimately slowing down or stopping cancer cell divisionCell division is the process by which one cell splits into two new cells. This is how our bodies grow, replace old cells, and heal injuries. Normal cells go through a carefully controlled cycle of growth and division.Cancer: Division Out… Read More.
- Disrupted Energy Production: Glutamine contributes significantly to energy production in cancer cells. DON interferes with this process, leading to energy depletion and potentially triggering cell death.
- Redox Imbalance: Glutamine helps maintain the delicate balance of oxidizingOxidation is a chemical reaction that involves the loss of electrons from a molecule, atom, or ion.
