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 کاملDoes Monosodium Glutamate Induce Obesity in Female Mice?
Objective: Female metabolism is highly responding towards diet associated changes. Monosodium glutamate is a popular flavor enhancer, which is widely used to develop umami taste. Young female generation nowadays deals with more issues related to metabolism and fertility. Present study is an effort to monitor the effect of monosodium glutamate oral consumption on female mice health and obesity. ...
متن کاملThe taste of monosodium glutamate: membrane receptors in taste buds.
Receptor proteins for photoreception have been studied for several decades. More recently, putative receptors for olfaction have been isolated and characterized. In contrast, no receptors for taste have been identified yet by molecular cloning. This report describes experiments aimed at identifying a receptor responsible for the taste of monosodium glutamate (MSG). Using reverse transcriptase (...
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 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...
