Is there a difference between Monosodium Glutamate and Monosodium L-Glutamate?

Monosodium Glutamate (MSG) and Monosodium L-Glutamate refer to the same compound, which is the sodium salt of glutamic acid, an amino acid. The "L" in Monosodium L-Glutamate indicates the specific stereoisomer of glutamate that is biologically active and commonly found in food. In most contexts, the terms are used interchangeably, as MSG primarily consists of the L-form, which is responsible for its flavor-enhancing properties.
