Amino acid metabolism is a complex and essential process in the human body that involves the interconversion of amino acids for various physiological functions. Amino acids serve as the building blocks of proteins, neurotransmitters, and other important molecules. Through processes like transamination and deamination, amino acids can be modified to produce energy, synthesize new proteins, or generate other important compounds. The liver plays a central role in amino acid metabolism by regula...
