Amino acids are the building blocks of the body. They build cells, repair tissue, form antibodies and combat invading bacteria and viruses. They are part of the enzyme and hormonal system and they build nucleoproteins (RNA and DNA). Amino acids carry oxygen throughout the body and participate in muscle activity. When protein is broken down by digestion, the result is 22 known amino acids. These are the building blocks of polypeptides and proteins.
