MSG is a salt of the amino acid glutamic acid. It's considered a flavor enhancer and is often used in cooking to enhance the savory (umami) flavor of foods.
Here's a breakdown:
* Salt: MSG is formed by the reaction of glutamic acid with sodium hydroxide.
* Amino acid: Glutamic acid is one of the 20 amino acids that make up proteins.
* Flavor enhancer: MSG doesn't have its own distinct flavor, but it enhances the existing flavors of food.
It's important to note that while MSG is generally safe for consumption, some individuals may experience mild side effects like headaches or nausea.
