Aspartic acid is a type of amino acid, which are the building blocks of proteins. It is classified as a non-essential amino acid, meaning that the body can produce it on its own. Aspartic acid plays a crucial role in various metabolic processes and is involved in the synthesis of other amino acids and neurotransmitters. This amino acid is found in many foods, including meat, eggs, and dairy products, as well as in plant-based sources like legumes and nuts. Aspartic acid is also important for the production of energy in cells and supports the functioning of the nervous system.
