A sweet-tasting crystalline nonessential amino acid, C2H5NO2, that is the principal amino acid occurring in sugarcane. The simplest amino acid found in protein, it is derived from the alkaline hydrolysis of gelatin and used in biochemical research and medicine. ...
It is generally assumed that the prebiotic synthesis of peptides occurs in two stages. The first stage is the formation of amino acids, and the second is their polymerization20. The polymerization process requires the condensation of amino acids accompanied by the loss of water. This has a high...

The a-amino acids in peptides and proteins (excluding proline) consist of a carboxylic acid (-COOH ) and an amino (-NH 2) functional group attached to the same tetrahedral carbon atom. This carbon is the a-carbon. Distinct R-groups, that distinguish one amino acid from another, also ...
The simplest might be an inability of MPC knockout hearts to satisfy the energy demand of the myocardium due to the decreased transport and oxidation of pyruvate in the mitochondria. However, ATP and adenylate energy charge remained unchanged in hearts where MPC was deleted in adulthood [22, 24...
