High quality of D-Aspartic Acid from China at HANGZHOU TONGGE ENERGY TECHNOLOGY CO., LTD. It is an alpha-amino acid, and the L-isomer of aspartate is one of the 20 protein amino acids. It is the same acidic amino acid as glutamic acid. It is one of the non-essential amino acids in the human body. Aspartic acid is commonly found in biosynthesis. It is a precursor to the synthesis of amino acids such as lysine, threonine, isoleucine, methionine and purine and pyrimidine bases in living organisms. It participates in the ornithine cycle, promotes ammonia and carbon dioxide production of urea, reduces the amount of nitrogen and carbon dioxide in the blood, enhances liver function, and eliminates fatigue.
