Although gustin and TAS2R38 contribute to the supertaster phenotype and may contribute to the perception of fat texture, researchers are still looking for a receptor directly triggered by fat. One promising candidate is the protein CD36, which binds long-chain fatty acids in mice, and is expressed on taste buds.  The mechanism by which the CD36 carrier protein initiates a neural signal is poorly understood.  CD36 may serve as a carrier protein that transfers the fatty acid to another receptor or it may activate an ion channel that alters the excitability of taste cells.

It may be more a tactile than a taste sensation.

"Mouth feel" was the ad men's definition.

Fats may tickle the tongue in an enticing way that lack of fats do not.
