Tongue chemoreceptors detect L-glutamate and other amino acids. Some receptors {glutamate receptor} {umami receptor} are metabotropic receptors similar to brain glutamate receptors and underlie savory taste (Kikunae Ikeda) [1908]. People with glutamate receptors can detect monosodium glutamate. Other receptors {amino-acid receptor} are altered sweet receptors that bind amino acids. Glutamate and amino-acid receptors couple to G-proteins, which have unknown second messengers.
