The Structure of Peptide Molecules and Related Facts
Peptide is a chain of amino acid residues that are linked together by a peptide bond. Peptide chains of more than fifteen amino acids are known as polypeptide and have been isolated and studied for their physiological functions in various organisms. Peptide chains have an important role in biological processes and also play a major role in DNA structure. Peptide molecules are formed through a series of chemical reactions when amino acid molecules are linked together by a peptide bond.Feel free to visit official site
Peptide chains can be constructed by connecting peptide residues of different length using peptide bond formation processes. Peptide bonding is a highly spontaneous reaction that requires energy and can generate large amounts of free radicals. The sequence of bonds determines the stability of the protein molecule and also the stability of the resulting peptide chain. Polypeptide chains are unstable and tend to break easily when exposed to environmental stress such as ozone and UV light. Therefore, it is necessary to contain peptide in a non-volatile form that is not affected by these environmental factors.
A peptide molecule may be single, double, or triple -strand, symmetric, or amphipolar. A single-stranded peptide isomer isomerizes as a molecule containing only a single pair of amino acids. A double-stranded peptide isomerizes in an opposite order of the sequence, creating a molecule that contains two sets of amino acids. Finally, a tripeptide peptide isomerizes in the same order as the sequence but with three sets of amino acids.
