Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. [1] Although over 500 amino acids exist in nature, by far the most important are the 22 α-amino acids incorporated into proteins. [2] Only these 22 appear in the genetic code of life. [3] [4]
In organic chemistry, a carboxylic acid is an organic acid that contains a carboxyl group (−C(=O)−OH) [1] attached to an R-group. The general formula of a carboxylic acid is often written as R−COOH or R−CO 2 H, sometimes as R−C(O)OH with R referring to an organyl group (e.g., alkyl, alkenyl, aryl), or hydrogen, or other groups ...
The parent of this family of ligands is the amino acid glycine, H 2 NCH 2 COOH, in which the amino group, NH 2, is separated from the carboxyl group, COOH by a single methylene group, CH 2. When the carboxyl group is deprotonated the glycinate ion can function as a bidentate ligand , binding the metal centre through the nitrogen and one of two ...

The C-terminus (also known as the carboxyl-terminus, carboxy-terminus, C-terminal tail, carboxy tail, C-terminal end, or COOH-terminus) is the end of an amino acid chain (protein or polypeptide), terminated by a free carboxyl group (-COOH). When the protein is translated from messenger RNA, it is created from N-terminus to C-terminus. The ...

Glycine N-carboxyanhydride is the parent member of the amino acid N-carboxyanhydrides.. NCAs are typically prepared by phosgenation of amino acids: [4]. They were first synthesized by Hermann Leuchs by heating an N-ethoxycarbonyl or N-methoxycarbonyl amino acid chloride in a vacuum at 50-70 °C: [5] [6]
Dipeptides are produced by coupling amino acids. The amino group on one amino acid is rendered non-nucleophilic (P in eq) and the carboxylic acid group in the second amino acid is deactivated as its methyl ester. The two modified amino acids are then combined in the presence of a coupling agent, which facilitates formation of the amide bond:
