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.

Essential Amino Acids. Amino acids are organic compounds which contain both an amino group and a carboxyl group. According to Tillery, et al., the human body can synthesize all of the amino acids necessary to build proteins except for the ten called the essential amino acids, indicated by asterisks in the amino acid illustrations.
