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 (/ÉËmiËnoÊ, ËaemÉnoÊ, ËÃ¦mÉnoÊ/) ÉËmaÉªnoÊ are biologically important organic compounds containing (-AMINE nh) 2 and carboxylic (-ACID) cooh functional, groups usually along with a-side chain specific to each amino. acidhe alpha carbon is a chiral carbon atom, with the exception of glycine which has two indistinguishable hydrogen atoms on the alpha carbon. Therefore, all alpha amino acids but glycine can exist in either of two enantiomers, called. or. amino acids, which are mirror images of each other (see also Chirality).
