Amino acids are the building blocks that form polypeptides and ultimately proteins. Consequently, they are fundamental components of our bodies and vital for physiological functions such as protein ...

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 ...

Each protein is a molecule made up of different combinations of 20 types of smaller, simpler amino acids. Protein molecules are long chains of amino acids that are folded into a three-dimensional ...

Branched-chain amino acids (BCAAs), include the essential amino acids leucine, isoleucine, and valine. BCAAs differ from other amino acids because they have a branched structure and are the only ...

BCAAs, short for branch-chain amino acids, are three types of essential amino acids. BCAA benefits include reduced fatigue, muscle soreness, and helping with weight loss. Use a BCAA supplement ...
