Amino acids are the most important components of the proteins that make up muscle fibers. Branched chain amino acids are unique in that their structure allows them to be metabolized primarily by skeletal muscle. And with the right forms of amino acids, muscle maintenance can be extremely rewarding. Branched chain amino acids are essential amino acids that can be metabolized by particular muscles. Special cells, called satellite cells, then transfer the amino acids to fuse and rebuild the torn fibers. In addition to calories and other nutrients, muscles also need amino acids. Branched chain amino acids have been shown to have other advantages as well. Essential amino acids consist of 8 amino acids and must come from food sources. These actually refer to three of the eight essential amino acids. This is due to each of the controlled biological processes that your control muscle fibers need to react in a specific way. More specifically, amino acids play a crucial role in this process. In this way, the muscles directly receive the proteins necessary for their growth and maintenance before being used by other biological processes. These proteins can also inhibit the breakdown of muscle proteins, which can contribute to more efficient growth and overall maintenance. However, non-essential amino acids can be synthesized by the body.
