Aspartic Acid and the Vegetarian Diet
Aspartic acid is an alpha-amino acid that is used in the biosynthesis of proteins. It is one of the 20 proteinogenic amino acids and is categorized as a non-essential amino acid, meaning it can be synthesized by the human body. Aspartic acid exists in two forms: L-aspartic acid, which is biologically active, and D-aspartic acid. It is involved in the urea cycle and gluconeogenesis and is found in a variety of foods, especially those high in protein such as meat, eggs, and soy products.
