Structure of Proteins - Primary Structure

A protein can have up to four levels of structures but all proteins have all four levels. 

Primary Structure of Protein: 

  • The specific sequence of amino acids in the polypeptide chain is called the primary structure.
  • The linear polymer of amino acids, called the polypeptide contains polarity.
  • By convention, the beginning of any polypeptide chain is at the α-amino group and the end is at the α-carboxyl group.
  • Each amino acid is called a residue.
  • The unique sequence for every polypeptide is determined by the genes encoding that protein.
