DOI: 10.1038/s41467-023 ... Most amino acids are synthesized from α-ketoacids, and later transaminated from another amino acid, usually glutamate. The enzyme involved in this reaction is an aminotransferase. α-ketoacid + glutamate ⇄ amino acid + α-ketoglutarate Glutamate itself is formed by amination of α-ketoglutarate: α-ketoglutarate + NH 4 ⇄ glutamate orbelus winery

Amino acids are designated as α- when the amino nitrogen atom is attached to the α-carbon, the carbon atom adjacent to the carboxylate group. There are several ways to classify amino acids; however, they are often grouped by the polarity of their side chains, as depicted in the graphic at the head … Meer weergeven Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although over 500 amino acids exist in nature, by far the most important are the alpha-amino acids, which comprise Meer weergeven In the structure shown at the top of the page, R represents a side chain specific to each amino acid.
