Interaction of the studied pentapeptide with myeloperoxidase-Cl -H 2O 2 system as well as with hypochlorite showed that in the peptide molecule individual amino acids oxidize consecutively according to their susceptibility to oxidation. No splitting of peptide bonds was observed. Therefore, a modified...
Amino Acids, Peptides and Proteins 5.20.7 Relevance of Amino Acids 5.20.7.1 What Is an Amino Acid? Amino acids are bifunctional compounds and the basic structural units/building blocks of proteins. In chemistry, an α-amino acid consists of an amino group, a carboxyl group, an R-group, an...
β-Amino acids are frequently found as important components in numerous biologically active molecules, drugs and natural products. In particular, they are broadly utilized in the construction of bioactive peptides and peptidomimetics, thanks to their increased metabolic stability. Despite the number of ...

Amino acids are linked together by peptide bonds forming long chains of tens or hundreds of amino acids (proteins). The peptide bond takes place between a carbon atom (carboxyl group) and nitrogen (amino group). This link, covalent type, is very stable and sturdy, making it possible to for...
Proteins are polymers with a constant backbone region (the peptide bonds) and variable side chains (the ‘R’ side chains of amino acids). The chemical properties of the side chain of each amino acid (e.g., its size, charge, or hydrophobicity) and the order in which the amino acids are...
