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.

Amino acids are exactly what they say they are! They are compounds containing an amino group, -NH 2, and a carboxylic acid group, -COOH. The biologically important amino acids have the amino group attached to the carbon atom next door to the-COOH group. They are known as 2-amino acids.
