Concept Introduction:
Protein is a long chain of polypeptide in which number of amino acids are linked to each other to produce a structure known as protein.
Each amino acid consists of carboxyl end and amino group which are joined through peptide linkage to produce dipeptide, tripeptide and polypeptide according to number of amino acids linked to each other.
Disulfide bond is formed by two sulfur that bonded to each other. Two amino acid such as cysteine make a dipeptide by formation of disulfide linkage.
Cysteine having polar side chain such as S carrying partial negative charge and H carrying partial positive charge. The structure of cysteine is follows:
