3+] can suppress vascular NO production in endothelial cells. Abnormal vessels can cause obstruction by either encircling the trachea and esophagus (complete vascular ring) or compressing the anterior wall of the trachea alone.
Î±-Amino acid (alpha-amino acid): A molecule containing an amino group and a carboxylic acid group that are separated by one carbon, called the Î±-carbon. In biochemistry there are twenty standard amino acids which differ in the makeup of the side chain (R group) attached to the Î±-carbon.-Amino acid (alpha-amino acid): A molecule containing an amino group and a carboxylic acid group that are separated by one carbon, called the Î±-carbon.

A branched-chain amino acid (BCAA) is an amino acid having aliphatic side-chains with a branch (a central carbon atom bound to three or more carbon atoms).Among the proteinogenic amino acids, there are three BCAAs: leucine, isoleucine and valine. Non-proteinogenic BCAAs include norvaline and 2-aminoisobutyric acid. branched-chain amino acid (BCAA) is an amino acid having aliphatic side-chains with a branch (a central carbon atom bound to three or more carbon atoms).
