Glossary -   Branched-chain amino acids (BCAA)



These are amino acids that have a chemical structure that looks like branches on a tree. Leucine (leu), valine (val), and isoleucine (ile) are three of the BCAAs. They are found in all foods that contain protein. Large amounts are found in meat, eggs, milk, and other dairy foods. Smaller amounts are found in flour, cereal, and in some vegetables and fruits.
