Glutamate taste: Discrimination between the tastes of glutamate agonists and monosodium glutamate in rats.
Taste aversion studies have demonstrated that rats conditioned to avoid monosodium glutamate (MSG) with amiloride added to reduce the intensity of the sodium component of MSG taste, generalize this aversion to aspartic acid and to L-AP4, but not to ionotropic glutamate receptor agonists. That is, MSG, L-AP4 and aspartate have similar tastes to rats. However, conditioned taste aversion methods a...
متن کاملMonosodium glutamate and sweet taste: discrimination between the tastes of sweet stimuli and glutamate in rats.
Generalization of a conditioned taste aversion (CTA) is based on similarities in taste qualities shared by the aversive substance and another taste substance. CTA experiments with rats have found that an aversion to a variety of sweet stimuli will cross-generalize with monosodium glutamate (MSG) when amiloride, a sodium channel blocker, is added to all solutions to reduce the taste of sodium. T...
متن کاملAre the tastes of polycose and monosodium glutamate unique?
To study whether Polycose and monosodium L-glutamate (L-MSG) have unique tastes differing from the traditional four basic tastes, chemosensory profiles were established for Polycose, L-MSG and a group of related compounds (sucrose, maltose, monosodium D-glutamate (D-MSG), sodium chloride, calcium chloride). Flavors were assessed using whole-mouth tests in human subjects with nose open or clampe...
متن کاملBehavioral comparisons of the tastes of L-alanine and monosodium glutamate in rats.
Recent research has implicated T1R1/T1R3 as the primary taste receptor in mammals for detecting L-amino acids, including L-monosodium glutamate (MSG) and L-alanine. Previous behavioral studies with rodents found only minimal evidence that these two substances share perceptual qualities, but those studies did not control for the taste of sodium associated with MSG. This study used several behavi...
متن کاملSucrose and monosodium glutamate taste thresholds and discrimination ability of T1R3 knockout mice.
Molecular and behavioral studies have identified heterodimers of the T1R family as receptors for detecting the tastes of sweet (T1R2 + T1R3) and umami (T1R1 + T1R3). However, behavioral studies have reported conflicting findings with T1R3 knockout (KO) mice. One study showed a complete or nearly complete loss of preference for sweet and umami substances by KO mice, whereas KO mice in another st...
