PY - 2018 T2 - The Big Picture: Medical Biochemistry AB - Amino acids are the basic building blocks of proteins and serve as biological molecules in their own right with a variety of functions. Amino acids are often categorized as essential or non-essential, depending on the ability of the body to manufacture each amino acid versus requirement for ingestion from the diet. Although several hundred amino acids exist, 20 play a predominant role in the human body. Each amino acid has a characteristic R-group that determines its chemical nature and, therefore, how it will interact with other amino acids, other molecules, and with its environment.
