Is Acesulfame Potassium Bad for Me? Medically reviewed by Elaine K. First, what are calories, nutritionally speaking? Second, what constitutes a sweet taste? Calories are a measure of the energy made available when we digest and metabolize food.
The energy drives the replacement of molecules we have lost, enables us to move, and so forth; we store excess energy as fat. A substance that we do not metabolize releases no energy it "has no calories" and is not a food. A sweet taste results from the binding of molecules to specific receptor proteins in our taste buds.
Sweet-taste-sensory cells in the taste buds have these receptor protein molecules embedded in their plasma membranes. Binding of a molecule to a receptor protein initiates a cascade of events within the taste-sensory cell that eventually releases a signaling molecule to an adjoining sensory neuron, causing the neuron to send impulses to the brain.
Within the brain, these signals derived from the taste bud cause the actual sensation of sweetness. Other sensory cells, with different receptor proteins, report on other taste modalities: salty, sour, bitter, and "umami" also referred to as glutamate, or "meat". The events that occur between binding by the "sweet receptor" and the sensation in the brain have nothing to do with whether a molecule can be metabolized to yield energy and thus "has calories.
So, what determines this binding ability? In April , two research teams published independent contributions to answering this question. Both papers announced and described a protein, dubbed T1r3, which appears to be the primary receptor for sweet substances. The molecular structure of T1r3 can be seen here. Like all receptor proteins, T1r3 has a well-defined "pocket" where smaller molecules may enter and perhaps bind. Binding depends on a good fit of molecular shape and the presence of groups that interact chemically to stabilize binding.
