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.

Generally spoken, an amino acid is a carboxylic acid containing an amino substituent. In most cases, the term âamino acidâ refers to an Î±-amino acid. Amino and carboxyl moiety are linked to the same carbon atom, the Î±-carbon. Glycine, Î±-aminoacetic acid, is the simplest amino acid, the parent compound of this class of substances. Î²-alanine is the parent compound of the Î²-amino acids.
