amino acid n. Any of various compounds containing an amino group (NH2), a carboxylic acid group (COOH), and a distinctive side chain, especially any of the 20 amino acids that link together to form proteins. Some amino acids (called nonessential) can be synthesized in the human body, whi...
Activation of the carboxyl group on either subjected amino acid building block or peptide segment that is supposed to be spliced to the reciprocal peptide fragment bearing to-be-acylated amino group or other relevant substituent constitutes one of the key steps in the peptide synthesis process. ...
An important artificial meal-flavoring food additive is the monosodium salt of glutamic acid.PeptidesWhen the amino group of one amino acid reacts with the carboxyl group of another amino acid, a peptide bond is formed and a mole 19、cule of water is released. This can bond joins amino ...
1.3). In turn, those side groups can show different groups such as hydroxyl groups (–OH) and, in conjunction with the carboxyl and amino group of the main structure of the amino acid, these affect the structure of a protein. Sign in to download full-size image Fig. 1.3. Typical ...
In this context, the salt bridges with the carboxyl group are a form of extra strong hydrogen bonding52. Interaction patterns with the backbone atoms of the amino acid ligand are strikingly consistent within Class II aaRSs. This class forms hydrogen bonds with the primary amine group in 92.15%...

The organic compounds that contain a functional amino group (NH2) and a carboxyl group (COOH) along with a side chain (R) are known as amino acids. The essential elements of an amino acid are hydrogen, carbon, oxygen, and nitrogen. There are around 5000 synthetically designed amino acids ...
Nineteen different amino acids of general formula H2N-CHR-COOH can be used as monomers in protein synthesis, and these vary only in the nature of the side group R. A list of possible side groups is shown in Table I. In addition an imino acid, proline, with a cyclic side chain and ...
