- Triggered by sodium ions (Na+).
- Crucial for regulation of electrolytes and fluid balance in the body.
-
Sweet:
- Associated with glucose and other sugars.
- Signals presence of nutritious, energy-rich food sources.
-
Umami:
- Associated with amino acids, particularly glutamate.
- Indicates protein-rich foods, contributing to nutritional value.
-
