![]() The sequence of amino acids in a polypeptide chain is dependent on the sequence of nucleotides in the gene encoding the protein. Thus, it can also form additional peptide bonds at both of its ends.Īll the amino acids present in a protein are together linked and sequenced via peptide bonds to form long linear chains. The resultant dipeptide also has a free amino group on one end and a free carboxylic group on the other end. It is a covalent bond that is formed when the carboxylic group of one amino acid reacts with the amino group of another amino acid. All the properties and functions of a protein are dependent on the sequence of amino acids in the peptide chains present in it.Īt the level of primary structure, we study the sequence of amino acids that are linked via peptide bonds in the polypeptide chains present in a protein. This is the basic level of protein structure. Primary StructureĪt this level of protein structure, the sequence of amino acids in proteins is studied. In this article, we will study these four levels of protein structure. ![]() ![]() In order to understand this complexity, the structure of proteins is studied at four levels of organization: Rather, the chains of amino acids are arranged to form molecules having complex structures. The amino acids present in these long chains determine the final structure, properties, and functions of proteins.Īmino acids in proteins don’t lie in linear chains. These amino acids are linked together via peptide bonds in the form of long chains. Proteins are the organic molecules made up of amino acids. What is the secondary structure of proteins?. ![]() ![]()
