Aspartic acid is one of the non-essential amino acids, normally synthesized by the body if the biological compounds are present in the body in sufficient amounts. Stamina in the body is increased by aspartic acid, and this amino acid is considered good for physical fatigue. Aspartic acid also performs a vital role in body level metabolism in the human body. Lowered levels of aspartic acid in the body may induce chronic fatigue in the body, this occurs due to lowered cellular energy in the body of the person. The presence of aspartic acid is believed to be beneficial for many neural and brain disorders affecting a person. The amino acid aspartic acid is said to be beneficial for athletes, and it is believed to help in the protection of the liver by affecting the elimination of excess ammonia from the body. Molecules that absorb toxins and remove them from the bloodstream are formed by combinations of the aspartic acid with other amino acids. Aspartic acid also aids in the functioning of cellular systems and in the biochemical function of RNA and DNA as well - these bio-molecules are the carriers of genetic information in the body. Aspartic acid also promotes the production of immunoglobulins in the body as well as the synthesis of antibodies -both of these bio-molecules are part of the proteins important in the immune system. Aspartic acid is found in great abundance in certain kinds of plant protein, particularly those found in certain sprouting seeds, aside from the animal protein sources.
