In the gp120 core structure (Fig. 2), the polypeptide chain is folded into discrete structural domains, each derived from discontiguous regions of the primary sequence: a relatively conserved ...

Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds ... a protein is considered the primary structure of the protein.

each with a specific side chain that gives it unique chemical properties. Amino acids are joined together by peptide bonds to form polypeptide chains. The sequence of amino acids in a protein, known ...

Proteins form the structural and functional backbone of the cell, and any perturbation in their synthesis can disrupt normal ...
