Three of the most important amino acids in the body are leucine, isoleucine and valine, collectively known as branched-chained amino acids (BCAAs). They are most important in maintaining muscle tissues, preserving muscle glycogen stores and preventing muscle breakdown during strenuous exercise.
Figure 1: The relationship between amino acid side chains and protein conformation. The defining feature of an amino acid is its side chain (at top, blue circle; below, all colored circles). When connected together by a series of peptide bonds, amino acids form a polypeptide, another word for protein. The polypeptide will then fold into a specific conformation depending on the interactions (dashed lines) between its amino acid side chains.
