Summary
BitterX identifies human bitter taste receptors (TAS2Rs) for chemicals. This open-access tool successfully predicted and validated novel bitterants, aiding bitter taste research and discovery.
Area of Science:
- Pharmacology and Cheminformatics
- Sensory Science
- Molecular Biology
Background:
- Human bitter taste perception is mediated by taste receptors, TAS2Rs.
- Identifying small molecules that activate specific TAS2Rs is crucial for understanding taste and developing new compounds.
- Existing methods for TAS2R identification can be time-consuming and resource-intensive.
Purpose of the Study:
- To develop and validate BitterX, an open-access computational tool for predicting human TAS2Rs for small molecules.
- To integrate bitterant verification and TAS2R recognition functionalities into a single platform.
- To facilitate the discovery of novel bitterants and their corresponding receptors.
Main Methods:
- BitterX utilizes molecular structure analysis to predict TAS2R interactions.
- The tool integrates two core functionalities: bitterant verification and TAS2R recognition.
- Predicted interactions were subjected to experimental validation.
Main Results:
- BitterX successfully predicted several novel bitterants and their cognate TAS2Rs.
- Experimental validation confirmed the accuracy of BitterX's predictions.
- The study demonstrated the tool's efficacy in identifying previously unknown bitter taste interactions.
Conclusions:
- BitterX provides an effective computational approach for deciphering bitter taste coding.
- The open-access nature of BitterX promotes accessibility for academic research and industrial applications.
- BitterX is a valuable tool for advancing basic bitter taste research and accelerating the discovery of new bitterants.

The Physiology of Taste
8.2K
The perception of a salty flavor is facilitated by sodium ions within the oral salivary fluid. Upon consumption of a salty substance, salt crystals disassemble, leading to the liberation of its constituents—Na+ and Cl- ions. These ions subsequently dissolve into the salivary fluid present in the oral cavity. The external environment of the gustatory cells experiences an elevation in Na+ concentration, thereby establishing a potent concentration gradient. This gradient propels the...

Taste Buds and Receptors
5.8K
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

Gustation
53.5K
Gustation is a chemical sense that, along with olfaction (smell), contributes to our perception of taste. It starts with the activation of receptors by chemical compounds (tastants) dissolved in the saliva. The saliva and filiform papillae on the tongue distribute the tastants and increase their exposure to the taste receptors.

Conditioned Taste Aversion
1.5K
Conditioned taste aversion, also known as sauce béarnaise syndrome, is a phenomenon in which an individual develops an aversion to a certain food taste following a negative experience, typically illness. This form of aversion is a type of classical conditioning in which the taste of the food (conditioned stimulus, CS) is associated with the experience of illness (unconditioned stimulus, UCS).
A notable characteristic of conditioned taste aversion is that it often requires only a single...

The Tongue and Taste Buds
42.1K
The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells.

What is Monogastric Digestion?
78.5K
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.
